AI Technical Summary
Existing methods for producing disposable incontinence diapers are inefficient and costly, particularly in terms of process technology, due to complex control processes and material usage in creating diaper side panels.
A method involving the use of multiple material webs with different properties, including inextensible and elastic materials, is employed to create a two-use diaper side panel web that can be reliably separated into single-use sections, with closure elements added for secure attachment to the main diaper part, utilizing techniques like ultrasonic welding and folding for efficient production.
This method enables cost-effective production of disposable incontinence diapers with improved stability and ease of use, as the two-use diaper side panel web is efficiently converted into single-use sections, enhancing the manufacturing process and reducing material waste.
Abstract
Description
[0001] Title: Method for the production of disposable incontinence diapers
[0002] Description
[0003] The present invention relates to a method for producing a plurality of
[0004] Open-type disposable incontinence diapers for adults.
[0005] Such disposable incontinence diapers are known and often have a main part consisting of a front area, a back area and a [missing information]
[0006] The diaper features a crotch area located between the legs of the user, in the longitudinal direction of the diaper, with the main part usually already including an absorption core, and separate diaper side panels attached to both sides of the rear lateral longitudinal edges of the back area, which extend in the transverse direction of the diaper beyond the lateral longitudinal edges of the main part and connect the front and back areas when the item is worn.
[0007] The diaper side panels are preferably attached directly to both sides of the main part, i.e., the chassis of the hygiene product, using the cut-and-place method (slip-cut).
[0008] Manufacturing technology allows the diaper side panels to be made from a different material than the main part of the hygiene product. For example, the diaper side panels can include elastic material, at least in some areas, whereas the main part can be made from a material that is essentially non-stretchable.
[0009] The most efficient, simplest and most cost-effective way from a manufacturing perspective to
[0010] Providing diaper side panels involves separating them from a continuous sheet of flat material. This sheet can be made of a composite material, such that continuous sheets, differing in their material properties (e.g., elasticity or breathability) as needed, are joined together at their respective longitudinal edges.
[0011] W02008 / 036706A1 discloses a method for manufacturing diaper side panels using a diaper side panel web with a single cut in the transverse direction, which has three differentiable areas in the transverse direction. The diaper side panels are separated by cutting the diaper side panel web in the transverse direction, in particular such that successively formed diaper side panels are oriented rotated by 180° in the plane.
[0012] WO2011 / 101773A1 discloses a method for manufacturing hygiene products, wherein a diaper side panel web with two crosswise uses is fed to a main web, wherein the diaper side panel web is manufactured such that outer side panel sections are cut from a first pre-folded material web and indexed to a second pre-folded material web. The indexed insertion of the outer side panel sections to the second material web entails a complex process.
[0013] WO96 / 03952A1 discloses a method for manufacturing a diaper, wherein
[0014] Diaper ear sections consisting of a first and a second ear, as well as a bridge material inserted between them, made of an endless composite
[0015] The material web is cut and attached to the main diaper part in such a way that the bridging material covers the main diaper part. The bridging material has a negative impact on the manufacturing costs of the diaper.
[0016] W096 / 31 180A1 discloses a method for manufacturing a closure system for hygiene articles, wherein an endless closure material web is attached to two endless
[0017] Flat material webs are attached in such a way that the closure material web forms the central area of a two-ply diaper side panel web. Before singulation, the two-ply diaper side panel web must be cut, in particular with meandering cuts.
[0018] The cuts through the closure material will separate the diaper into two single-use side panels.
[0019] The present invention is based on the objective of providing an improved method for manufacturing such or similar disposable incontinence diapers, which is cost-effective and advantageously implementable from a process engineering perspective.
[0020] This task is solved by a process for producing
[0021] Disposable incontinence diapers, each disposable incontinence diaper containing one
[0022] has a diaper longitudinal direction and a diaper transverse direction, and wherein the
[0023] The disposable incontinence diaper has a main part provided with an absorbent core, wherein the main part has a back area with a first rear lateral longitudinal edge and a second rear lateral longitudinal edge, and wherein a first elastic diaper side panel extending in the transverse direction of the diaper beyond the first rear lateral longitudinal edge of the main part is attached to the first rear lateral longitudinal edge, and wherein a side panel extending in the
[0024] A second elastic diaper side panel extending transversely in the diaper direction beyond the second rear lateral longitudinal edge of the main part is attached, comprising the following steps
[0025] Conveying a first material web, a second material web, a third material web, a fourth material web, and a fifth material web, wherein the first material web has a width B1 and a first material web edge region and a second material web edge region and comprises or consists of an attachment material that is substantially inextensible in a transverse direction of the first material web, wherein the second material web has a width B2 and a third material web edge region and a fourth material web edge region and comprises or consists of a first material that is at least partially elastic in a transverse direction of the second material web, wherein the third material web has a width B3 and a fifth material web edge region and a sixth material web edge region and comprises or consists of a second material that is at least partially elastic in a transverse direction of the third material web.wherein the fourth material web has a width B4 and a seventh material web edge region and an eighth material web edge region and comprises or consists of a first closure carrier material that is substantially non-stretchable in a transverse direction of the fourth material web, and wherein the fifth material web has a width B5 and a ninth material web edge region and a tenth material web edge region and comprises or consists of a second closure carrier material that is substantially non-stretchable in a transverse direction of the fifth material web, and wherein the material web edge regions of the first, second, third, fourth and fifth material webs are joined together such that the first, second, third, fourth and fifth material webs form a diaper side panel web that is dual-purpose in its respective transverse direction, such that a central region of the dual-purpose diaper side panel web is formed by the first material web,that a first outer area of the double-sided diaper side panel is formed by the fourth material layer, that a second outer area of the double-sided diaper side panel is formed by the fifth material layer, and that a first elastic area arranged in the transverse direction of the double-sided diaper side panel between the first outer area and the central area is formed by the second material layer, and that a,
[0026] The second elastic area, arranged in the transverse direction of the dual-purpose diaper side panel between the second outer area and the central area, is formed by the third material panel.
[0027] Separating the double-sided diaper side panel in a longitudinal direction and through the central area of the double-sided diaper side panel to form a first and second single-sided diaper side panel, each in its respective transverse direction; separating diaper side panel sections by separating the first and second single-sided diaper side panels in their respective transverse directions.
[0028] Feeding a diaper main web with a first diaper main web edge and a second diaper main web edge,
[0029] Attaching the diaper side panel sections to the first areas of the first diaper main panel edge and to the second areas of the second
[0030] Diaper main section edge,
[0031] Separating the disposable incontinence diapers by separating the
[0032] Diaper main web in a transverse direction of the diaper main web.
[0033] The inventive method enables the cost-effective provision of a material that is dual-purpose in the transverse direction and elastic in the transverse direction.
[0034] The diaper side web enables the process to be reliably separated into diaper side sections by process-efficient separation and singulation steps.
[0035] Unless otherwise described, within the scope of the present invention, the single, double or triple use of a respective track refers to its transverse direction, i.e. a direction orthogonal to the respective longitudinal direction of the track.
[0036] The "utility" factor (one, two, three) refers to the number of segments – for example, in the case of the diaper side panel, to the number of
[0037] Diaper side panel sections – which can be formed or separated from the web in the respective direction. That the first web of material and / or the section encompassed by the first web of material
[0038] Attachment material - by means of which the diaper side sections are attached to the
[0039] The diaper main panel edge is attached – being essentially non-stretchable – and also offers the advantage of increased stability of the joint between the
[0040] The increased thickness of the main diaper section and the attachment material of the diaper side sections is further enhanced. The fact that the fourth and / or fifth material layer and / or the closure carrier material preferably encompassed by the fourth and / or fifth material layer, to which closure elements are attached according to a preferred embodiment, is essentially inextensible also facilitates the creation of an articulated connection between closure elements and a respective diaper side section.
[0041] The closure carrier material of the fourth and / or fifth material web and / or the attachment material of the first material web preferably comprises or consists of a nonwoven material, such as spunbond nonwoven, meltblown nonwoven, carded nonwoven, spunlace nonwoven or through air bonded carded nonwoven, or combinations thereof. Particularly preferred are
[0042] Spunbond nonwovens and / or meltblown nonwovens,
[0043] especially laminates made from spunbond (S) and meltblown (M) nonwovens or
[0044] Nonwoven layers such as SMS, SSMS, SMMS, SSMMS, or SSMMSS laminates.
[0045] It has also proven advantageous if the nonwoven material contains at least one formulation component based on a thermoplastic polymer, such as polyethylene PE, polypropylene PP or polyethylene terephthalate PET or mixtures thereof.
[0046] Nonwoven materials including rayon, cellulose, polyamide PA and mixtures thereof are also conceivable.
[0047] The nonwoven material advantageously has a basis weight of 10 - 70 g / m². 2 , further
[0048] preferably 20 - 60 g / m² 2 , preferably from 30 - 50 g / m² 2 .
[0049] In a preferred embodiment, the first and second closure carrier material comprise or consist of the same material, in particular the same
[0050] Nonwoven material. According to a further preferred embodiment, the attachment material and the first and / or the second closure carrier material comprise or consist of the same material, in particular the same nonwoven material. This has the advantage that the attachment material and the closure carrier material, in particular two, and further in particular three, of the material webs selected from the group comprising the first material web, the fourth material web and the fifth material web, can be provided from a single material web, in particular two- or three-ply in the transverse direction, in particular by separating this material web in the longitudinal direction, in particular as described in more detail below.
[0051] Preferably, the first and second elastic materials comprise or consist of the same material.
[0052] The first and / or second elastic material of the second and / or the third
[0053] The material web further preferably comprises or consists of a flat material, in particular a nonwoven fabric, a film, a textile material, a foam, or combinations thereof. In particular, the first and / or second elastic material comprises or consists of a laminate of two or more of the aforementioned flat materials. Further preferably, the first and / or second elastic material can consist of a composite of elastic components and non-elastic components.
[0054] Components may be formed, in particular from a composite of an elastic film or an elastic nonwoven fabric or an elastic foam or elastic threads such as Lycra or Spandex or Elastane threads with a non-elastic and / or stretchable nonwoven fabric or foam.
[0055] In the case of a composite of elastic and non-elastic components, the composite can be made elastic by ensuring that the non-elastic component is stretchable and offers little or no resistance to the elastic stretching of the elastic component. Another possibility is to join the components using a stretch-bonding process known to those skilled in the art, thus joining the elastic component to the inelastic component in a pre-stretched state. A further way to achieve elasticization of a composite of elastic and non-elastic components is to "activate" the composite, preferably using a technology known as "ring rolling." This technology is described, for example, in EP 0 650 714 A1.Ring rolling is a process in which a composite material that is not inherently stretchable, such as a non-woven / film laminate, is overstretched by excessive deflection between intermeshing rollers. In this process...
[0056] In its overstretched state, the previously non-stretchable laminate material offers essentially no resistance to elongation. By combining it with an elastically stretchable element within such a laminate, elastic stretchability can be achieved in the treated area. According to a preferred embodiment of the method, the diaper side panel, which has two layers in the transverse direction, has a first axis of symmetry running along its longitudinal direction. Furthermore, and in particular, the separation of the diaper side panel occurs along this first axis of symmetry.
[0057] In a preferred variant, the third material web edge area of the second
[0058] The material web is attached to the first material web edge area of the first material web, and the fifth material web edge area of the third material web is attached to the second
[0059] The material web edge region of the first material web is attached, such that the first, second, and third material webs together form a composite web, wherein the materials of the first, second, and third material webs extend endlessly in a longitudinal direction of the composite web, and wherein the composite web has a first composite web edge region and a second composite web edge region, and wherein the seventh material web edge region of the fourth material web is attached to the first composite web edge region of the composite web, and wherein the ninth material web edge region of the fifth material web is attached to the second composite web edge region of the composite web, such that the composite web together with the fourth and fifth material webs forms the diaper side panel web, which is dual-purpose in its transverse direction, and wherein the materials of the fourth and fifth material webs extend endlessly in a longitudinal direction of the diaper side panel web.
[0060] According to a preferred embodiment of the method, it proves advantageous to attach the second and third material webs to the first material web simultaneously, i.e., in particular in the same process step.
[0061] According to another preferred variant, it proves advantageous to attach the fourth and fifth material webs to the composite web simultaneously, i.e., in particular in the same process step.
[0062] According to a preferred variant of the method, the composite liner has a second axis of symmetry running in the longitudinal direction of the composite liner.
[0063] According to a preferred embodiment, the first and the second elastic diaper side part each have at least one closure element.
[0064] According to another preferred variant, the respective closure elements are in particular timed and applied by means of application techniques known to those skilled in the art, such as the cut-and-place method (slip-cut), in particular to first areas of a first diaper side panel edge and to second areas of a second
[0065] Diaper side panel edge attached.
[0066] It proves advantageous if each diaper side panel has exactly one
[0067] The diaper side panel features a closure element. These closure elements are typically a flap made of a single- or multi-layered flat material, which, starting from a configuration usually folded inwards around a distal longitudinal edge of the diaper side panel, can be unfolded into an outwards unfolded operating position. Alternatively, the closure carrier material of a respective diaper side panel may have a functional closure element ("patch") within the distal area of the diaper side panel. In a manner known per se and therefore not requiring further description, each closure element is equipped with adhesive and / or mechanically bonded areas, layers, or elements, such as hook / loop materials. If the diaper side panel has exactly one closure element, it proves advantageous if this closure element is located in the
[0068] The fastening element is positioned approximately centrally and distally along the length of the diaper side panel. Furthermore, it is advantageous if the fastening element extends between 25% and 75% of the longitudinal extent C of the diaper side panel. The fastening elements are preferably rectangular in both the folded and unfolded states. In the manufacturer's inactive configuration, they are preferably folded inwards towards themselves.
[0069] In use, the diaper side panels overlap with a
[0070] The fastening elements are positioned on the side of the main part facing away from the body, i.e., on the outside, of the front section of the main part, so that the fastening elements provided at each end of the diaper side section (free in the transverse direction of the diaper) can be closed onto the outside of the front section of the main part. For this purpose, the fastening elements and at least one area of the outside of the front section of the main part are designed as a fastening system. In particular, the fastening elements have mechanical components such as hook-and-loop fasteners, especially in combination with adhesive areas, by means of which the fastening elements can be detachably brought into contact with the outside of the front section of the main part. It has proven advantageous for the outside of the front section of the main part to be formed at least partially, preferably completely, by a suitably designed nonwoven fabric.Alternatively, it is possible to provide one or more separate hook and loop fastener elements on the outside of the main part in the front area, which serve as a landing zone for the fastening elements of the diaper side panels.
[0071] Furthermore, it proves advantageous to attach the closure elements to the diaper side panel, which has two uses in the transverse direction. Alternatively, it is conceivable to provide the fourth and fifth material layers with closure elements before attaching the respective material layer to the composite layer. As a further alternative, it is conceivable to attach closure elements to the diaper side panels, which have one use in the transverse direction, or to the
[0072] Adding diaper side panel sections is also possible.
[0073] Fastening elements to the diaper side panels after attaching the diaper side panels to the main part or after separating the disposable incontinence diapers.
[0074] Preferably, the second and third material webs are provided by separating a first material web that is double-sided in its transverse direction.
[0075] Preferably, the fourth and fifth material webs are provided by separating a second material web that is double-sided in its transverse direction.
[0076] According to a further preferred embodiment, the first, fourth and fifth material webs are provided by separating a material web that has three uses in its transverse direction.
[0077] It has proven advantageous to provide the material webs comprising elastic material, attachment material or closure carrier material, which are single-utilized in their respective transverse direction, by separating a material web that is two- or three-utilized in its respective transverse direction along its respective longitudinal direction.
[0078] This separation process can be carried out “in-line” in a manner known to those skilled in the art, such that the material webs obtained from the separation process, which are single-sided in their transverse direction, are directly subjected to the further process for the production of the
[0079] diaper side panel feed, or “off-line” in such a way that the single-use
[0080] Material webs are placed in a storage form and processed further at a later time or at a geographically distant operating site.
[0081] It has also proven advantageous to separate the single-use diaper side panels in their respective transverse direction by separating a double-use panel in their transverse direction.
[0082] To provide the diaper side panel along its longitudinal direction. This process can also be carried out "in-line" or "off-line" in relation to the manufacture of the disposable incontinence diaper.
[0083] Within the scope of this invention, the terms "separation in the longitudinal direction" or "separation along a longitudinal direction" preferably refer to separation along a straight dividing line running parallel to the longitudinal extent of the relevant web. Other line shapes are also conceivable, such as curved, bent, wavy, jagged, obtuse-angled, acute-angled, pointed-arch, shallow-arched, or irregular, whereby these line shapes produce web edges that are not straight.
[0084] The separation can be complete, i.e., continuous, or discontinuous, as a weakening line, for example by means of perforation or in the form of
[0085] Material recesses are created, with the separation being completed in a subsequent process step. For economic reasons, the separation is preferably carried out without generating any scrap material, but it can also result in a small amount of discardable material, for example, for aesthetic reasons.
[0086] Both the separation of tracks in the longitudinal direction and the separation of
[0087] Cutting diaper side sections from a diaper side section web in the transverse direction as well as singulating disposable incontinence diapers in the transverse direction can be done using different methods known to those skilled in the art, such as cutting, punching, laser cutting, fluid cutting (for example, water jet cutting).
[0088] A preferred embodiment provides that the diaper side panel sections are designed to be single-sided in their longitudinal direction. This includes a
[0089] Diaper side panel section exactly one diaper side panel of a single
[0090] Disposable incontinence diaper.
[0091] According to a further preferred embodiment, the diaper side panel sections are designed to be two-sided in their longitudinal direction, wherein the separation of the diaper main panel web is carried out through the diaper side panel sections such that a first
[0092] A section of each diaper side panel forms a rear diaper side panel of a first disposable incontinence diaper, and a second section of the respective
[0093] The diaper side section forms a rear diaper side section of a second disposable incontinence diaper that is immediately adjacent in a longitudinal direction. In such cases, the first and second sections are preferentially designed and essentially identical.
[0094] Preferably, the first and the second elastic diaper side part are folded onto themselves at at least one, in particular at least two, and further in particular at least three, preferably parallel to the longitudinal direction of the incontinence disposable diaper, fold lines FW1 extending towards themselves and in particular in this
[0095] Configuration is fixed and removable.
[0096] This type of folding of the diaper side panels proves advantageous both when packaging the disposable incontinence diaper and when putting it on.
[0097] Disposable incontinence diaper by the user. The resulting folded configuration can preferably be fixed by the manufacturer, for example by individual seams.
[0098] In particular, adhesive or welding joints, especially ultrasonic welds, which nevertheless can be relatively easily released manually by the user, especially in one go, to unfold the diaper side panels. In this case, a single [unclear] proves sufficient.
[0099] A fastening element positioned preferably approximately centrally on the diaper's side panels along its length is advantageous, wherein the joining points preferably do not engage the folded fastening element, but are arranged outside the fastening element in the diaper's length direction. If the adjoining sections are located around the at least one inwardly folded fastening element, or above or below the folded element in the diaper's length direction, the fastening element is advantageous.
[0100] If the locking element is detachably fixed by the aforementioned measures, the folded-in locking element forms an easily graspable gripping area for unfolding the respective diaper side panel.
[0101] In a further advantageous development of the design described above, it proves beneficial if the diaper side panels are folded by the manufacturer along at least two, and in particular at least three, fold lines FW1 extending in the longitudinal direction of the diaper, especially in a Z-shape, and if these fold lines FW1 define and delimit the folded sections of the diaper side panels, and further preferably that a section lying on the outside in the transverse direction is essentially inextensible. This particularly improves the ease of grasping and unfolding both the diaper side panel and the folded-in fastening element.Furthermore, it proves advantageous if a section adjoining the outer section on the inside, starting from a fold line running in the longitudinal direction of the diaper and closest to the end of the diaper side panel that is free in the transverse direction, is inextensible with at least 40% of its area. For the determination of this area, reference is made to WO 2017 / 140604 A1. This ensures that the area in the...
[0102] The outer part of the diaper, in the transverse direction, and the part adjoining it to the inside, lie flat against each other over a very large inextensible area (of at least 40% of the area of the latter part), which is therefore free of elastic or elasticizing elements.
[0103] In an advantageous further development of this embodiment, the extent E of a respective non-stretchable area of the sub-area adjoining the outer sub-area inwards, starting from the outer fold line running in the longitudinal direction of the diaper in the transverse direction of the diaper to the beginning of a stretchable area, is preferably at least 15 mm, in particular at least 20 mm, further in particular at least 25 mm, further preferably at least 30 mm, but preferably at most 100 mm, further preferably at most 85 mm, further preferably at most 70 mm.
[0104] For the folded configuration of the diaper side panels, it is preferably the case that a
[0105] The extension A of the diaper side panels folded on themselves in the transverse direction of the diaper extends beyond the respective rear lateral longitudinal edge, and the extension C of the diaper side panels folded on themselves in the longitudinal direction of the disposable incontinence diaper is dimensioned such that the ratio of the extensions A / C to each other is 0.5 < A / C <1.
[0106] To form the fold lines FW1 of the diaper side panels of the incontinence disposable diaper, it has proven advantageous if the double-sided diaper side panel is folded on itself on both sides by at least one, in particular by at least two, and further in particular by at least three fold lines FW2 parallel to the longitudinal direction of the double-sided diaper side panel, and in particular is detachably fixed in this configuration.
[0107] However, according to an alternative, the longitudinal folding of the diaper side panel can also be done after separating the two-purpose diaper side panel to form single-purpose panels.
[0108] Diaper side panels are created. In such cases, the single-use diaper side panels are folded onto themselves by at least one, in particular by at least two, and further in particular by at least three fold lines FW3 or FW4 parallel to a longitudinal direction of the respective single-use diaper side panel, and in particular detachably fixed in this configuration.
[0109] The folding of the diaper side panel sections around the fold lines FW2, FW3 or FW4 and in particular the double-purpose or single-purpose sections in their respective transverse direction
[0110] Diaper side panel, especially in combination with the fixation of the folded
[0111] Configuration using the methods described above results in the diaper side panel sections being pre-folded before being attached to the diaper main section. This has the advantage that the pre-folded diaper side panel sections are stiffer and shorter in their respective transverse directions than unfolded diaper side panel sections and are therefore easier to process, especially in high-speed machines. Alternatively, an embodiment is conceivable in which the folding of the diaper side panels occurs only after they have been attached to the
[0112] The main diapering process is complete.
[0113] Preferably, the diaper side panel sections are folded onto the diaper main panel, and in particular onto an upper surface of the diaper main panel. In such a case, the respective fold line around which a diaper side panel section is folded onto the diaper main panel can run within the diaper main panel or within the area of the diaper side panel section extending beyond the diaper main panel, i.e., outside the diaper main panel. The upper surface of the diaper main panel can be
[0114] the side away from the body, but especially the side facing the body
[0115] The main part of the diaper is the main section. Alternatively, it is conceivable that the sections formed by the diaper's side panels are only created after the disposable incontinence diapers have been separated.
[0116] The diaper side panels are folded onto the main part of the disposable incontinence diaper.
[0117] Before the manufacturer packages the disposable incontinence diaper, the main part, together with the diaper side panels folded inwards and / or the diaper side panels folded onto the main part, is preferably folded inwards by the manufacturer around a first and a second main part fold line running lengthwise along the diaper, preferably such that the two diaper side panels overlap each other in the thickness direction, i.e., orthogonally to a plane encompassing the diaper's lengthwise and crosswise directions, at least partially. Furthermore, preferably before the manufacturer packages the disposable incontinence diaper, the main part, together with the diaper side panels folded inwards, and preferably following the previously described folding inwards along the
[0118] The main part fold lines running lengthwise in the diaper are additionally preferably folded towards themselves by at least one or two main part fold lines running in the transverse direction of the diaper, in such a way that a body-facing side of the main part lies directly or indirectly on itself, at least in some areas.
[0119] In a preferred embodiment of the present invention, the individual disposable incontinence diapers are joined by at least one, in particular two, in a
[0120] Diaper transverse direction extended fold lines FQ folded.
[0121] It should be noted that the webs, namely the first, second, third, fourth and fifth material webs and the composite web, each have web edges on both sides, with a web edge area extending flatly towards the other web edge of the respective web adjoining the web edges.
[0122] When joining two tracks, these tracks are each conveyed along their respective longitudinal direction, preferably parallel to each other, such that the two tracks preferably come to lie flat next to each other.
[0123] The joining of two webs can be carried out using joining methods known to those skilled in the art, in particular by thermal welding, ultrasonic welding, sewing, sealing or gluing, wherein the two webs are preferably permanently joined together.
[0124] The two tracks to be joined can be joined with their respective track edge areas pointing towards the other track, i.e., "butted together", with or without additional material tracks bridging the joint between the two tracks.
[0125] It has proven particularly advantageous to guide the two tracks to be joined overlapping with their respective track edge areas pointing towards the other track, and to join the tracks inextricably in an overlap or joining area formed thereby by the above-mentioned joining methods known to those skilled in the art.
[0126] In a preferred embodiment, a quotient Q1 of the width B1 and the sum of the widths B2 and B3, calculated as: B1 / (B2+B3), has a value of 0.2 to 1.5, in particular a value of 0.25 to 1.2, in particular a value of 0.25 to 1.0, in particular a value of 0.3 to 0.9, in particular a value of 0.4 to 0.8, and / or a quotient Q2 of the width B1 and the sum of the widths B4 and B5, calculated as: B1 / (B4+B5), has a value of 0.15 to 1.5, in particular a value of 0.2 to 1.2, in particular a value of 0.2 to 1.0, in particular a value of 0.25 to 0.7, in particular a value of 0.3 to 0.5.
[0127] It is also preferred that B1 <(B2+B3) and / or that B1 <(B4+B5).
[0128] The width B1 of the first material web is preferably 50 - 150 mm, in particular 70 - 130 mm, and more particularly 90 - 110 mm.
[0129] The width B2 of the second material web and / or the width B3 of the third material web is preferably 20 - 130 mm, in particular 30 - 120 mm, and more particularly 40 - 100 mm.
[0130] The width B4 of the fourth material web and / or the width B5 of the fifth material web is preferably 50 - 200 mm, in particular 60 - 190 mm, and further in particular 70 - 180 mm.
[0131] In the event that, when joining the first and second and / or third material webs, the edges pointing towards the respective adjacent webs are not properly aligned, the following applies:
[0132] The track edge areas are laid out overlapping, the width B6 of the
[0133] The overlap area of the first material web with the second material web and / or a width B7 of the overlap area of the first material web with the third material web is preferably 3 - 17 mm, further preferably 5 - 15 mm, further preferably 6 - 13 mm.
[0134] In the event that, when joining the composite sheet and the fourth and / or fifth material sheet, the sheet edge areas pointing towards the respective adjacent sheet are overlapped, the width B8 of the overlap area is
[0135] Composite membrane with the fourth material layer and / or a width B9 of the
[0136] The overlap area of the composite sheet with the fifth material sheet is preferably 3 - 17 mm, more particularly 5 - 15 mm, more particularly 6 - 13 mm.
[0137] In a preferred embodiment, the width B11 of the composite membrane is 150 - 400 mm, in particular 170 - 350 mm, and more particularly 200 - 300 mm.
[0138] The width B10 of the diaper side panel, which is double-sided in its transverse direction, is preferably 300 - 650 mm, in particular 320 - 630 mm, and more particularly 340 - 610 mm.
[0139] A quotient Q3 of the width B11 (numerator) and the width B10 (denominator) preferably has a value of 0.25 - 0.8, more particularly 0.3 - 0.75, and more particularly 0.4 - 0.7. Furthermore preferably, the longitudinal extent of the single-use diaper side panel sections and / or the single-use diaper side panels in the diaper's longitudinal direction is 110 - 170 mm, more particularly 120 - 160 mm, and more particularly 130 - 150 mm.
[0140] The width B1 of the first material web, the width B2 of the second material web, the width B3 of the third material web, the width B4 of the fourth material web, the width B5 of the fifth material web, the width B1 1 of the composite web and the width B10 of the diaper side panel web, which is double-purpose in its transverse direction, are each measured in mm in the transverse direction of the respective web, i.e. along a transverse extension that runs at an angle of 90° to the longitudinal direction of the respective web, in the flat, unfolded and unstretched state.
[0141] Within the scope of the present invention, the term "width" is to be understood as the maximum extent in the transverse direction of the respective path.
[0142] Likewise, the respective widths B6, B7, B8 or B9 of the overlapping or
[0143] Joining areas and the widths B2e and B3e of the effective elastic areas of the double-sided diaper side panel in the transverse direction, described in more detail below.
[0144] Double-sided diaper side panel measured in the flat, unfolded state.
[0145] Longitudinal or transverse dimensions and widths of the disposable incontinence diaper and / or its first or second elastic side panels, namely the dimension E, the distance D, and the widths B2e.1, B1.1 and B4.1 described in more detail below, are measured in the flat, unfolded and unstretched state of the
[0146] Disposable incontinence diapers and / or their first and second elastic diaper side panels, i.e., with regard to the stretching of the elastic diaper side panels in the state of initial handling by the user, but after complete unfolding of the
[0147] Manufacturer-made folds of the disposable incontinence diaper and / or its elastic diaper side panels measured in mm.
[0148] The extensions A and C of the first and second elastic diaper side panels are measured in mm in the flat, unfolded and unfolded state of the incontinence disposable diaper, whereby the first or second elastic diaper side panel remains in the folded, unstretched and flat unfolded state.
[0149] It should be noted here that the term "unstretched" is to be understood as meaning that the unfolding and flattening of the elastic diaper side panels occurs without the tensile forces typically exerted by the user when putting on the disposable incontinence diaper, so that the material of the unstretched elastic diaper side panels remains in the relaxed state intended by the manufacturer before use. The present invention also encompasses a disposable incontinence diaper manufactured or manufacturable according to all of the preceding or following embodiments. The disposable incontinence diaper is particularly preferably designed as a so-called T-shaped diaper. Specifically, no diaper side panels are attached to the front of the disposable incontinence diaper.
[0150] The main part of the disposable incontinence diaper preferably comprises a topsheet that is at least partially permeable to liquid and a preferably breathable and preferably at least partially impermeable backsheet, which surround the absorbent core in a sandwich-like manner. Furthermore, the disposable incontinence diaper can have cuff elements on both sides of the body-facing side of the crotch area, forming a lateral leakage barrier and / or extending along the longitudinal length of the absorbent core on both sides. The cuff elements preferably comprise a nonwoven material ("cuff fleece"), in particular a hydrophobic nonwoven material, or are formed from such a material.
[0151] Preferably, the topsheet and / or backsheet and / or cuff fleece extend beyond the contour edges of the absorbent core at least in the transverse direction of the diaper, and preferably also in the longitudinal direction, to form a corresponding overhang. Within this overhang, the backsheet and topsheet and / or cuff fleece are preferably at least partially joined to one another, particularly by joining methods known per se such as...
[0152] Welding, sealing, sewing or gluing.
[0153] Advantageously, the main part in the crotch area has, on both sides adjacent to a respective longitudinal edge of the crotch area, a feature extending in the diaper's longitudinal direction.
[0154] Disposable incontinence diapers extend an elastic or elasticized section, specifically an elastic or elasticized leg opening section. "In the diaper's longitudinal direction" here means that the elastic or elasticized leg opening section extends at least one
[0155] component in the longitudinal direction of the diaper, and therefore may also run obliquely or curved to the longitudinal direction of the diaper.
[0156] Preferably, elastic threads known to those skilled in the art (Lycra® or similar) are fixed in a pre-tensioned state to the materials forming the main part, preferably to the top and / or back sheet of the main part, particularly in an area where the top and / or back sheet and / or cuff fleece form an overhang outside the contour edges of the absorbent core. According to one variant, an elastic or elasticized leg opening section can also be formed by flat or band-shaped materials such as elastic bands, films, nonwovens, or foams. The absorbent core is suitable and intended for absorbing and permanently storing bodily excretions, especially body fluids, particularly urine. For this purpose, the absorbent core can advantageously contain superabsorbent polymer material (SAP), particularly 5–100% by weight, preferably 10–95% by weight, more preferably 15–90% by weight, and most preferably 20–80% by weight.
[0157] Weight percent. Typically, SAP material can absorb at least 15 times, and in particular 20 times, its weight in 0.9 weight percent saline solution (measured according to NWSP 242.0.R2(15)).
[0158] The SAP material can be, for example, particle-shaped, fibrous, sheet-shaped, or foam-shaped.
[0159] The absorbent body can hold other materials, such as wood pulp fibers or
[0160] It contains plastic fibers. It is also conceivable to form the absorbent body by arranging one or more layers of different materials, especially non-woven fabric.
[0161] The suction body is preferably an integral part of the main part and, in that case, is permanently bonded to the other components of the main part by the manufacturer. In that case, the suction body is preferably permanently bonded to a top sheet and / or a back sheet of the main part.
[0162] To test whether a material is to be classified as "elastic" in the respective direction, the following permanent set test is to be carried out within the scope of the present invention:
[0163] For the tests, a Shimadzu AG-Xplus tensile testing machine, conforming to DIN EN ISO 7500-01:2004-11, with a lower fixed clamping jaw and an upper movable clamping jaw, was used. Preferably, the test device has software that controls the test cycle and ensures automated recording of the force values.
[0164] When carrying out the test method, the rectangular material section to be tested is ideally provided as a test specimen with a width of 25 mm and a length of 60 mm (the length corresponds to the direction of pull). For this purpose, the test specimen is, for example, punched out from a corresponding elastic component of the disposable incontinence diaper or from a respective material web, whereby the direction of pull of the test specimen corresponds to the transverse direction of the disposable incontinence diaper or the transverse direction of the material web.
[0165] Ideally, the 25 mm wide and 60 mm long (tensile direction) test specimen is clamped into the clamps of a tensile testing machine with a clamping jaw spacing of 40 mm.
[0166] A preload of 0.05 N is applied, and a cyclic movement (loading and unloading, test speed 500 mm / min) is performed between L0 (length of the test section at a preload of 0.05 N) and a maximum elongation of 60%, without a dwell time at the upper reversal point. Upon unloading, the final length L1 is also recorded at 0.05 N.
[0167] The permanent set (PS) is calculated as follows:
[0168] PS = ((L1-L0):L0)x100 [%].
[0169] A material is considered elastic in the respective direction if the permanent elongation is less than 25%.
[0170] If a 25 mm wide section of the component to be tested is not available, a correspondingly narrower section is used. If a 60 mm long section of the elastic component is not available, a correspondingly shorter section is used, whereby the jaw spacing, and thus the effective length of the test section, may need to be reduced to as little as 15 mm. It must be ensured that the section is firmly clamped in the jaws.
[0171] To determine whether a material or component is to be classified as "non-stretchable" in the respective direction, the following test is to be carried out within the scope of the present invention:
[0172] For carrying out the tests, a tensile testing machine type Shimadzu AG-Xplus, according to DIN EN ISO 7500-01 :2004-11, with lower fixed clamping jaw and upper
[0173] A movable clamping jaw is used. Preferably, the test device has software that controls the test cycle and ensures automated recording of the force values.
[0174] When carrying out the test method, the rectangular material section to be tested is ideally provided as a test specimen with a width of 25 mm and a length of 60 mm (the length corresponds to the direction of pull). For this purpose, the test specimen is, for example, punched out from a corresponding component of the disposable incontinence diaper or from a respective material web, whereby the direction of pull of the test specimen corresponds to the transverse direction of the disposable incontinence diaper or the transverse direction of the material web.
[0175] Ideally, a 25 mm wide and 60 mm long (tensile direction) test specimen of the material is placed in the clamps of the tensile testing machine under a preload of 0.05 N.
[0176] The specimen is clamped with a jaw spacing of 40 mm and stretched (loaded, test speed 500 mm / min) up to a force of 5 N. If the elongation at a force of 5 N is less than 30%, the material is considered inextensible within the scope of the present invention. If the specimen breaks during the above test before the maximum force of 5 N is reached, the material is also considered inextensible in the respective direction within the scope of the present invention.
[0177] If a 25 mm wide section of the component to be tested is not available, a correspondingly narrower section is used. In such a case, instead of a force of 5 N, the required force value is calculated by reducing the load of 5 N by a factor of f1, which is given by f1 = 25 / x, where x is the width of the test specimen measured in mm. Example: a 12.5 mm wide test specimen would be subjected to a force of 2.5 N.
[0178] If a 60 mm long section of the elastic component is not available, a correspondingly shorter section will be used, whereby the clamping jaw spacing, and thus the effective length of the test section, may need to be reduced to as little as 15 mm.
[0179] to ensure that the section is firmly clamped in the jaws.

[0216] With reference to Figures 1, 2, 3a, 3b, 3c, an exemplary method according to the invention for the production of disposable incontinence diapers 17 is described below. The exemplary method comprises several steps, namely separating, joining, folding, and
[0217] Singulation steps and the application of closure elements, which are described in more detail in the following figures. In a preferred embodiment, a material web 2, which is three-sided in its transverse direction 25 and essentially comprises inextensible material in its transverse direction 25, is processed in a first cutting station S1, namely
[0218] Attachment material or closure carrier material, in its longitudinal direction 24 in three (with
[0219] (Reference symbols 3, 4 and 5) each single-use in their transverse direction
[0220] Material webs, namely the first material web 3, the fourth material web 4, and the fifth material web 5, are separated. A material web 6, which is two-sided in its transverse direction 25 and which includes elastic material at least partially in the transverse direction 25, is cut longitudinally in a second cutting station S2 into two webs, each with a single-sided cross-section.
[0221] Material webs, namely the second material web 7 and the third material web 8, are separated, wherein the second material web 7 and the third material web 8 each comprise at least partially elastic material in their transverse direction. The material webs are subsequently fed to one another and joined together, such that in a first joining station U1 the first material web 3, which essentially comprises (or consists of) joining material, and the second material web 7 and third material web 8, each comprising at least partially elastic material in the transverse direction 25, are joined together in such a way that they together form a composite web 9, in which the joining material of the first material web 3 is located in the transverse direction 25 between the second
[0222] The material web 7 and the third material web 8 are arranged, such that in the transverse direction 25 the attachment material of the first material web 3 forms a central area 53. In a further joining station U2, the fourth material web 4 and the fifth material web 5, each comprising (or consisting of) essentially non-stretchable closure carrier material in the transverse direction 25, are attached to the composite web 9 as described in more detail below, such that the composite web 9 is positioned in the transverse direction 25 between the fourth
[0223] Material web 4 and the fifth material web 5 are arranged, and the composite web 9 together with the fourth material web 4 and the fifth material web 5 forms a
[0224] In the transverse direction 25, a two-purpose diaper side panel 10 is formed. In a taper station T, closure elements (“tapes”) 44 are attached to both sides of the closure carrier material of the
[0225] The two-purpose diaper side panel 10, comprising the fastening elements 44, is fed to a folding station F1, where the two-purpose diaper side panel 10 is folded along its longitudinal direction 24 on both sides.
[0226] The fold lines FW2 50 are folded onto themselves. The resulting folded configuration can preferably be fixed by the manufacturer, for example by individual
[0227] Joining points, in particular adhesive or welding points, especially ultrasonic welding points, which nevertheless allow for the development of the properties described in more detail below.
[0228] Process steps, namely cutting, singulation and joining steps, from the
[0229] The diaper side panels formed by the dual-purpose diaper side panel are relatively easy for the user to detach manually, especially in one go.
[0230] The self-folding, two-purpose diaper side panel 10 is fed to a cutting station S3 and there in the central area 53, which includes the attachment material, in
[0231] Longitudinally 24 into two single-use diaper side panels 13a and 13b in the transverse direction 25. The single-use diaper side panels 13a and 13b are in a
[0232] Singulation station V1 separates the diaper side sections 14a and 14b in the transverse direction 25. The diaper side sections 14a and 14b are joined with an endless diaper main web 15 in a joining station U3 and preferably attached to the diaper main web 15 on both sides by ultrasonic welding, and in particular by pulsed welding. The singulation of the diaper side sections 14a and 14b and their attachment to the diaper main web 15 can be carried out by the cut-and-place method (slip-cut) known to those skilled in the art; however, all other application techniques known to those skilled in the art and suitable for this purpose are also possible. The diaper main web 15, which has diaper side sections on both sides, is then joined to a second
[0233] The diaper main web 15 is fed to singulation station V2, where it is cut in the transverse direction 25, forming individual disposable incontinence diapers 17. The disposable incontinence diapers 17 can then be fed to further processes such as additional folding steps and / or packaging.
[0234] In this embodiment, the joining of webs in the joining stations U1 and / or U2 and / or U3 is particularly preferably carried out by ultrasonic welding, however any other joining method known to the skilled person and suitable for the purpose, in particular thermal welding, sewing, sealing or gluing, is also possible.
[0235] The separation of the material webs in the cutting stations S1 and / or S2 and / or S3 can be carried out in this example using different methods known to those skilled in the art, such as cutting, punching, laser cutting, fluid cutting (for example, water jet cutting).
[0236] The singulation of the diaper side sections 14a and 14b in the singulation station V1 and the incontinence disposable diapers 17 in the singulation station V2 can be carried out using different methods known per se to those skilled in the art, such as
[0237] for example cutting, punching, laser cutting, fluid cutting (for example waterjet cutting).
[0238] Figure 2a shows in perspective, not to scale, but schematically.
[0239] Example illustration of the provision of the second material track 7 and the third
[0240] Material web 8 by separating the dual-purpose material web 6. The dual-purpose
[0241] Material web 6 is unwound endlessly from a first roll 20 and along its
[0242] The material is conveyed in the longitudinal direction 24. The transverse direction 25 of the two-ply material web 6 runs orthogonally, i.e., at a right angle 26, to the longitudinal direction 24. At the cutting station S2, a cutting device 21 separates the two-ply material web 6, which comprises (or consists of) elastic material in the transverse direction 25, into two single-ply material webs in the transverse direction 25, namely the second material web 7, which comprises or consists of a first elastic material in its transverse direction 25, and the third material web 8, which comprises or consists of a second elastic material in its transverse direction 25. The first elastic material is preferably identical to that of the second elastic material; thus, the first and second elastic materials preferably consist of the same material.The second material layer 7 and the third material layer 8 are preferably approximately the same width in the transverse direction 25; however, another variant is conceivable in which the second material layer 7 and the third material layer 8 are of different widths. Figure 2b shows a schematic, not to scale, perspective view.
[0243] The illustration shows, by way of example, the provision of the first material web 3, the fourth material web 4 and the fifth material web 5, wherein the first material web 3 essentially comprises (or consists of) inextensible attachment material in the transverse direction 25, and wherein the fourth material web 4 comprises a first inextensible material in its transverse direction 25
[0244] The fifth material web 5 comprises or consists of a second, transversely inextensible 25 closure carrier material, by separating a transversely three-ply material web 2, which essentially comprises or consists of transversely inextensible 25 material. The three-ply material web 2 is unwound continuously from a second roll 22 and conveyed along its longitudinal direction 24. The transverse direction 25 of the three-ply material web 2 is orthogonal, i.e., at a right angle 26, to the longitudinal direction 24. At the cutting station S1, a cutting device 23 separates the three-ply material web 2 into three transversely single-ply material webs, namely the first material web 3, the fourth material web 4, and the fifth material web 5.In the present case, the first and second closure carrier materials and the attachment material comprise or consist of the same material, in particular the same nonwoven fabric material. At least the fourth material web 4 and the fifth material web 5 are preferably approximately the same width in the transverse direction 25, preferably approximately the same width or each wider than the first material web 3. In Figure 2b, the cutting device 23 is formed by two knives arranged side by side, so that the two cutting operations occur approximately simultaneously. Alternatively, it is conceivable that the knives are arranged offset along the longitudinal direction 24 of the three-layer material web 2 such that the two cutting operations occur sequentially.As an example, in Figure 2b the material webs are arranged such that the fourth material web 4 is formed from a central area of the three-purpose material web 2 and the first material web 3 and the fifth material web 5 are formed on both sides of the material web 4 from distal areas.
[0245] Areas of the material web 2. However, any other arrangement of the first material web 3, the fourth material web 4 and the fifth material web 5 along the transverse direction 25 is also conceivable. Figures 3 a to c show an exemplary detailed representation of the
[0246] Arrangement and execution of the process steps for the production of
[0247] Disposable incontinence diapers 17.
[0248] Figure 3a shows, not to scale, but schematically an exemplary embodiment of the joining steps of the first material web 3, second material web 7, third material web 8, fourth material web 4 and fifth, which refer to Figures 2a and 2b.
[0249] Material track 5 in top view.
[0250] The first material web 3 has a first material web edge region 30 and a second material web edge region 31. The second material web 7 has a third
[0251] The third material web has a fifth material web edge area 34 and a sixth material web edge area 33. The third material web 8 has a fifth material web edge area 34 and a sixth material web edge area 32 and a fourth material web edge area 33.
[0252] Material web edge area 35. The fourth material web 4 has a seventh
[0253] The fifth material web has a ninth material web edge area 40 and a tenth material web edge area 39. The fifth material web 5 has a ninth material web edge area 40 and a tenth material web edge area 38.
[0254] Material web edge area 41 on.
[0255] The first material web 3, which has a width B1, is guided overlapping the second material web 7, which has a width B2, such that the first
[0256] Material web edge area 30 of the first material web 3 with the third
[0257] The edge area 32 of the second material web 7 forms an overlap or joining area with a width B6, within which the first material web 3 and the second material web 7 are permanently joined together at the joining station U1. The first material web 3 is guided overlapping the third material web 8, which has a width B3, such that the second edge area 31 of the first material web 3 overlaps the fifth edge area 34 of the third material web 8.
[0258] An overlap or joining area with a width B7 is formed, within which the first material web 3 and the third material web 8 are permanently joined together at the joining station U1. The first material web 3, the second material web 7, and the third material web 8 together form the composite web 9 with a width B11 and a second axis of symmetry 100. The composite web 9 further has a first
[0259] Composite membrane edge area 36 and a second composite membrane edge area 37.
[0260] The composite sheet 9 is guided overlapping the fourth material sheet 4, which has a width B4, such that the first composite sheet edge area 36 of the composite sheet 9 overlaps with the seventh material sheet edge area 38 of the fourth material sheet 4.
[0261] An overlap or joining area with a width B8 is formed, within which the composite sheet 9 and the fourth material sheet 4 are permanently joined together at the joining station U2. The composite sheet 9 is guided overlapping with the fifth material sheet 5, which has a width B5, such that the second edge area 37 of the composite sheet 9 and the ninth edge area 40 of the fifth material sheet 5 form an overlap or joining area with a width B9, within which the composite sheet 9 and the fifth material sheet 5 are permanently joined together at the joining station U2. The composite sheet 9, the fourth material sheet 4, and the fifth material sheet 5 together form the two-purpose material 25 in the transverse direction.
[0262] Diaper side panel 10 with a width B10 and a first axis of symmetry 101.
[0263] In this exemplary embodiment, width B1 is 100 mm, width B2 is 90 mm, and width B3 is 90 mm. Width B1, at 100 mm, is smaller than the sum of widths B2 and B3, which is 180 mm. The quotient Q1 of width B1 (numerator) and the sum of widths B2 and B3 (denominator) in this embodiment is 0.6 [calculation: Q1 = (B1 / (B2+B3)), i.e., Q1 = (100 mm / (90 mm + 90 mm))].
[0264] In this variant, width B4 is 170 mm and width B5 is also 170 mm. The quotient Q2 of width B1 (numerator) and the sum of widths B4 and B5 (denominator) has a value of 0.3 [calculation: Q2=(B1 / (B4+B5)), i.e., Q2=(100 mm / (170 mm + 170 mm))].
[0265] The width B6 of the overlap area or joining area formed by the first material web 3 and the second material web 7 has a value of 10 mm.
[0266] The width B7 of the overlap area or joining area formed by the first material web 3 and the third material web 8 has a value of 10 mm.
[0267] The width B8 of the overlap area or joining area formed by the composite sheet 9 and the fourth material sheet 4 has a value of 10 mm.
[0268] The width B9 of the overlap area or joining area formed by the composite sheet 9 and the fifth material sheet 5 has a value of 10 mm.
[0269] The width B10 of the double-purpose diaper side panel 10 has in this
[0270] Example embodiment shows a value of 580 mm.
[0271] In this embodiment, the width B1 1 of the composite sheet 9 has a value of 260 mm.
[0272] A quotient Q3 of width 1 (numerator) and width 10 (denominator) has a value of 0.45.
[0273] In this embodiment, the distance B2e in the transverse direction 25 of the diaper side panel 10 between the overlap or joining area formed by the first material web edge area 30 and the third material web edge area 32 and the overlap or joining area formed by the first composite web edge area 36 and the seventh material web edge area 38 is 70 mm.
[0274] In this embodiment, the distance B3e in the transverse direction 25 of the diaper side panel 10 between the overlap or joining area formed by the second material web edge area 31 and the fifth material web edge area 34, and the overlap or joining area formed by the second composite web edge area 37 and the ninth material web edge area 40, is 70 mm. B2e and B3e thus denote the widths of the respective effective elastic areas of the two-layer diaper side panel 10, since the elastic properties of the materials of the second and third material webs may be impaired in the respective overlap and joining areas.
[0275] The dual-purpose diaper side panel 10 has a first diaper side panel edge 42 and a second diaper side panel edge 43 and is fed to a taper station T, in which the respective closure elements 44 are attached to first areas of the first
[0276] Diaper side panel edge 42 and to second areas of the second
[0277] The diaper side panel edge 43 is attached.
[0278] In the preferred embodiment shown in Figure 3a, the second
[0279] Material web 7 and the third material web 8 are simultaneously attached to the first material web 3, so that the first material web 3 together with the second material web 7 and the third material web 8 together form the composite web 9. Subsequently, the fourth material web 4 and the fifth material web 5 are again simultaneously attached to the
[0280] Composite layer 9 is attached. Any other sequence or combination of the attachment steps is equally conceivable and encompassed by the present invention.
[0281] In this embodiment, the joining of material web edge areas in the joining stations U1 and / or U2 is particularly preferably carried out by ultrasonic welding, however any other joining method known to the skilled person per se and suitable for the purpose, in particular thermal welding, sewing, sealing or gluing, is also possible.
[0282] Figure 3b shows, not to scale, a schematic and top-view illustration of a preferred embodiment of the folding of the components provided with locking elements 44 and in
[0283] The cross-direction 25 of the two-purpose diaper side panel 10 is shown, along with the separation and singulation steps for forming the diaper side panel sections 14a and 14b. In this variant, the two-purpose diaper side panel 10 is fed to a folding station F1, where the two-purpose diaper side panel 10 is folded on both sides by two parallel sections.
[0284] Longitudinal direction 24 of the dual-purpose diaper side panel 10 extending fold lines FW2 50 is folded Z-shaped onto itself, whereby a dual-purpose section in the transverse direction 25, with
[0285] The diaper side panel 10 is formed by the fastening elements 44 and is folded inwards. The first diaper side panel edge 42 and the second
[0286] The diaper side panel edge 43 lies outside the respective self-folded area 51 in the transverse direction 25, i.e., outside the area between the two fold lines FW2 50. This arrangement is particularly advantageous because it forms a distal gripping area 56 projecting in the transverse direction 25, which facilitates the grasping and unfolding of the diaper side panels formed from the double-layered diaper side panel 10 by the user in further process steps described in more detail below.
[0287] In this exemplary embodiment, the double-sided diaper side panel 10 is folded onto itself on both sides by two fold lines FW2 50, in a Z-shape. Further variations, as illustrated in Figures 10b and 10c (but there with reference to the finished disposable incontinence diaper), include a single fold line FW2 on both sides, for example in a C-shape, or at least three fold lines FW2 on both sides, for example in a W-shape, around which the double-sided diaper side panel 10 is folded onto itself.
[0288] The diaper side panel 10, which is double-sided in the transverse direction 25 and folded inwards, is conveyed to a cutting station S3, where a cutting device 52 separates the double-sided diaper side panel 10 in the longitudinal direction 24. The separation takes place in the central area 53 of the diaper side panel 10, which includes the attachment material and is not folded inwards, such that two single-sided diaper side panel sections 13a and 13b are formed in the transverse direction 25. The single-sided diaper side panel sections 13a and 13b are fed to a singulation station V1, where they are cut in the transverse direction 25 to form separate diaper side panel sections 14a and 14b. An area 57 of the diaper side panel 10, which includes the attachment material, is cut in this process.
[0289] Diaper side section sections 14a or 14b are arranged on a longitudinal edge 58 of the diaper side section 14a or 14b opposite the respective gripping area 56.
[0290] The two-ply diaper side panel 10, which has not yet been folded around the fold lines FW2 50, includes the closure elements 44 in Figure 3b in an exemplary and preferred manner. However, an alternative arrangement of the process steps for attaching the closure elements 44 is also conceivable, such as attaching the closure elements 44 to the single-ply diaper side panels 13a and 13b in the transverse direction 25 or to the already separated diaper side panel sections 14a and 14b. Figure 3b shows a preferred variant in which the two-ply diaper side panel 10 is first folded onto itself in the folding station F1 and then separated in the longitudinal direction 24 into two single-ply diaper side panels 13a and 13b in the transverse direction 25 in the cutting station S3.Alternatively, as illustrated schematically and in plan view in Figure 4 (not to scale), the double-sided diaper side panel 10 is first cut approximately in the middle and longitudinally 24 in a cutting station S4 by means of a cutting device 75 in the central area 53, which includes the attachment material, thereby forming two single-sided diaper side panels 13a and 13b. In this case, the single-sided diaper side panels 13a and 13b are subsequently conveyed to a folding station F2 and folded there along two respective folding lines FW3 76 or folding lines FW4 77. The diaper side panels 13a and 13b, folded onto themselves and single-sided in the transverse direction 25, are fed to a singulation station V3, where the single-sided
[0291] Diaper side panels 13a and 13b are cut in transverse direction 25 such that individual diaper side panel sections 14a and 14b are formed.
[0292] The separation of the double-sided diaper side panel 10 in the cutting station S4 and / or the singulation of the diaper side panel sections 14a and 14b in the singulation station V3 can be carried out using various methods known to those skilled in the art, such as cutting, punching, laser cutting, fluid cutting (for example,
[0293] Waterjet cutting).
[0294] Figure 3c shows, not to scale, a schematic and top-view illustration of a preferred embodiment for attaching diaper side panel sections 14a and 14b to a diaper main panel 15. The diaper main panel 15 is conveyed to a joining station U3. In the joining station U3, the side panel sections, each comprising a closure element 44, are attached.
[0295] Diaper side sections 14a and 14b of the diaper main web 15 are fed in pairs, preferably in the longitudinal direction 24, preferably on both sides and preferably approximately opposite each other in the transverse direction 25. The diaper side section sections 14a and 14b are arranged such that they each form an overlap or joining area with a first area 60 or a second area 61 of the diaper main section 15 with at least a part of the respective area 57 comprising the attachment material on the longitudinal edge 58 of the respective diaper side section section 14a or 14b opposite the gripping area 56, within which the respective diaper side section section 14a or 14b and the diaper main section 15 are inseparably connected to each other in the joining station U3, wherein the diaper side section section 14a forms the first elastic diaper side section 62 and the diaper side section section 14b forms the second elastic diaper side section 63.
[0296] In this embodiment, the joining of the diaper side sections 14a and 14b with the diaper main section 15 in the joining station U3 is particularly preferably carried out by ultrasonic welding, however any other joining method known to the skilled person and suitable for the purpose, in particular thermal welding, sewing, sealing or gluing, is also possible.
[0297] The main diaper section 15 is fed into a singulation station V2, in which the
[0298] Disposable incontinence diapers 17 are separated by separating the main diaper panel 15 in a transverse direction 25.
[0299] In the illustrated embodiment, the diaper main web 15 consists of two
[0300] Flat material sheets, namely consisting of a top sheet 80 that is at least partially permeable to liquids and a layer that is at least partially
[0301] liquid-impermeable backsheet 81, between the, in
[0302] The absorbent cores 69 are inserted in a longitudinally oriented manner. The diaper side sections 14a and 14b, with their areas 57 encompassing the attachment material, are placed between the topsheet 80 and backsheet 81, as described in more detail with reference to Figure 12a. Alternatively, it is possible (see Figure 12b) that the
[0303] Topsheet layer 80 on both sides in transverse direction 25 of the diaper main layer 15 (or in
[0304] Diaper transverse direction 74, cf. Figure 12b) has a liquid-impermeable material (cuff fleece) with the function of a lateral leakage barrier, wherein in such cases the first elastic diaper side panel 62 and the second elastic diaper side panel 63 are placed between the backsheet 81 and the cuff fleece. Any other placement of the first elastic diaper side panel and the second elastic diaper side panel of the
[0305] However, disposable incontinence diapers with a thickness pattern in one direction are also conceivable.
[0306] According to a preferred variant (not shown in Figure 3c), the
[0307] Diaper side panel sections 14a, 14b after attaching diaper side panel sections 14a,
[0308] 14b to the main diaper panel 15, but before separating the incontinence disposable diaper 17, folded onto the main diaper panel 15.
[0309] Figure 5 shows, not to scale, a schematic cross-sectional view of a preferred embodiment of a diaper side panel 10 with two uses in the transverse direction 25. The first material panel 3, the second material panel 7, the third material panel 8, the fourth material panel 4, and the fifth material panel 5 are arranged side by side in the transverse direction 25 such that the respective directly adjacent material panels, with their respective edge regions pointing towards the nearest material panel, each form an overlap or joining region within which the respective panels are permanently connected to one another. Preferably, as shown in Figure 5, a [missing wording] is used in the respective joining or overlap regions.
[0310] In the wearing state of the disposable incontinence diaper, the body-facing upper surface 70 of the second material layer 7 and the third material layer 8 is connected to a body-facing upper surface 71 of the first material layer 3, the fourth material layer 4 and the fifth material layer 5. However, any other arrangement of the layers in the thickness direction 27 is also conceivable and included as a possible embodiment.
[0311] Figure 6 shows, not to scale, but schematically, a whole with the
[0312] Reference numeral 17 designates a disposable incontinence diaper in the so-called T-shape. The disposable incontinence diaper 17 comprises a main part, designated by reference numeral 65, with a body fluid-absorbing absorbent core 69. The absorbent core 69 preferably comprises cellulose fibers and superabsorbent materials.
[0313] Polymer particles (SAP). The absorbent body 69 is located between two flat materials, namely a liquid-permeable top sheet 80a and a
[0314] liquid-impermeable back sheet 81 a (backsheet) of the diaper main part 65 arranged.
[0315] The incontinence disposable diaper 17 has a diaper length of 73 and a
[0316] Diaper transverse direction 74 distinguishable, the latter in the applied state of the
[0317] The disposable incontinence diaper corresponds to the user's hip circumference. The main part 65 comprises a front area 82 with front lateral longitudinal edges 83, a
[0318] The back section 64 has a first rear lateral longitudinal edge 66 and a second rear lateral longitudinal edge 67 and a crotch section 84 arranged between them. Adjacent to each longitudinal edge 85 of the crotch section 84, the main part 65 has an elasticized section 86, i.e., an elasticized leg opening section.
[0319] These elasticized leg opening sections 86 are formed by elastic threads running between topsheet 80a and backsheet 81a and fixed to topsheet 80a and / or backsheet 81a in a pre-tensioned state, which are curved in an arc shape, thus being oriented at least sectionally in the diaper longitudinal direction 73.
[0320] In the T-shaped disposable incontinence diaper 17, a first elastic diaper side panel 62, extending laterally beyond the first rear lateral longitudinal edge 66 and formed by the diaper side panel section 14a (see also Figures 3b and 3c), and a second elastic diaper side panel 63, extending laterally beyond the second rear lateral longitudinal edge 67 and formed by the diaper side panel section 14b (see also Figures 3b and 3c), are provided in the back area 64 of the main part 65 in the transverse direction 74 of the diaper, and the two elastic diaper side panels 62 and 63 are formed by the diaper side panel section 14b (see also Figures 3b and 3c), which are connected in the area of the rear lateral longitudinal edges 66 and 67 respectively in a
[0321] The overlap area 87 is permanently attached to the back area 64 of the main part 65. In contrast, no diaper side panels are provided in the front area 82. The first elastic diaper side panel 62 and the second elastic diaper side panel 63 each have at least one [missing information] in the area of their end 88 that is free in the transverse direction 74 of the diaper.
[0322] Closure element 44. The closure element 44 is designed in the form of a preferably rectangular flap and is folded inwards by the manufacturer. In the usage situation, the closure element 44 can be opened, i.e., unfolded again, to put the disposable incontinence diaper 17 on a user, whereby the first elastic diaper side panel 62 and the second elastic diaper side panel 63 are brought into overlap with the front area 82 of the main part 65 and the closure elements 44 are detachably adhered to the side of the front area 82 of the main part 65 facing away from the user (schematically shown in Figure 7).
[0323] The first elastic diaper side panel 62 and the second elastic diaper side panel 63 have a distance D of preferably 5 - 50 mm in the longitudinal direction 73 of the diaper from a rear transverse edge 79 of the incontinence disposable diaper 17.
[0324] Figure 8 shows an enlarged section of the incontinence disposable diaper 17 according to Figure 6, specifically in the area of a first elastic diaper side part 62 in a flat, but not stretched, state with two fold lines FW1 68a and 68b.
[0325] When the first elastic diaper side panel 62 is described below, it is assumed that the second elastic diaper side panel 63 is merely
[0326] preferably in reverse but otherwise identically constructed and dimensioned. The same applies conversely when the second elastic diaper side panel 63 is described below.
[0327] In the present case, the fold lines FW1 68a, 68b correspond to the fold lines FW2 50 of the double-sided diaper side panel 10 (see Figure 3b). The formation of the
[0328] Diaper side panel sections as previously described with reference to Figures 1-4, the first elastic diaper side panel 62 comprises three directly adjoining areas in the transverse direction 74 of the diaper: a substantially inextensible distal area 90, a substantially inextensible proximal area 93, and an intervening elastic area 92. The distal area 90 of the first elastic diaper side panel 62 has the extension B4.1 in the transverse direction 74 of the diaper (where B4.1 corresponds substantially to the width B4, see Figure 3a), comprises substantially inextensible fastener carrier material, and forms the free end 88 of the first elastic diaper side panel 62. The fastener element 44 or the free end runs through this distal area 90 in the longitudinal direction 73 of the diaper.
[0329] 88 of the first elastic diaper side panel 62 nearest fold line FW1 68b.
[0330] The essentially non-stretchable proximal area 93 has an extent B1.1 in the diaper transverse direction 74, corresponding approximately to half the width B1 of the first material web 3 (see Figure 3a), and comprises the essentially non-stretchable attachment material. The proximal area 93 overlaps the diaper main part 65 and is inseparably connected to the diaper main part 65 in the overlap or joining area 87, as illustrated in more detail in Figure 3c.
[0331] The area 92, located between the distal region 90 and the proximal region 93 and elastic at least in the transverse direction 74 of the diaper, has an extension B2e.1 in the transverse direction 74 of the diaper (which corresponds to the extension B2e, Figure 3a). The fold line FW1 68a, which is closest to the main part of the diaper 65, runs through the elastic area 92 in the longitudinal direction 73 of the diaper.
[0332] In this embodiment, the extent E of an inextensible sub-area is
[0333] 89 of the sub-area 91 80 mm extending in the transverse direction of the diaper 74 between the two fold lines FW1 68a and 68b.
[0334] Figure 9 shows an enlarged section of the incontinence disposable diaper 17 according to Figure 6, specifically in the area of a second elastic diaper side part 63 with closure element 44 in a folded configuration with two fold lines FW1 68, in Z-configuration.
[0335] In the illustrated case, the extent C of the diaper side panel 63 in the longitudinal direction 73 is 140 mm. The extent A of the Z-configuration folded
[0336] Diaper side panel 63 measured from the free end 88 of the second elastic
[0337] The distance from the diaper side panel 63 to the second rear lateral longitudinal edge 67 of the main part 65 in the diaper transverse direction 74 is 80 mm in the illustrated case. The ratio of
[0338] The distance between A and C is 0.6 [Calculation: A / C=(80 mm / 140 mm)].
[0339] In this illustration, the folded configuration of the second elastic diaper side panel 63 is detachably fixed in the Z-configuration by joining points 94. Figure 10a shows a sectional view in the section plane III-III from Figure 6. In this embodiment, the section plane runs in the transverse direction 74 of the diaper in the back area 64 of a disposable incontinence diaper 17. This is not to scale, but schematic.
[0340] In the exemplary embodiment shown, a gap exists in the back area 64 between the top sheet 80a, which forms the upper surface 70 of the diaper main part 65 facing the body, and the back sheet 81a, which forms the upper surface 71 of the diaper main part 65 facing away from the body, and which together enclose an absorbent core 69.
[0341] The second elastic side panel 63 of the disposable incontinence diaper 17 is placed in the incontinence diaper. However, any other placement of the second elastic side panel 63 in the thickness direction 27 of the disposable incontinence diaper 17 is also conceivable and included as a possible embodiment.
[0342] In this design, the second elastic diaper side panel 63 is folded onto itself by two fold lines FW1 68, forming a so-called Z-configuration. The second elastic diaper side panel 63 is folded at the fold line FW1 68a closest to the main part 65 in its flat, unfolded state (i.e., in its unfolded state), in the direction of the upper surface 71 facing away from the body, and at the respective
[0343] The closure element 44 or the free end 88 of the second elastic diaper side panel 63 in the flat, unfolded state, i.e., in the unfolded state, is at the nearest fold line FW1 68b in the direction of the body-facing upper surface 70 of the
[0344] Disposable incontinence diaper 17, folded. This configuration has proven particularly advantageous for the user when unfolding the diaper's side panels. However, the reverse orientation of the folds around fold lines 68a and 68b is also possible.
[0345] Figures 10b and 10c show alternative embodiments of the folding of the second elastic diaper side panel 63, each not to scale, but
[0346] schematic sectional view shown.
[0347] Figure 10b shows a second elastic diaper side panel 63 folded in a W-shape around itself by three fold lines FW1 68, wherein the second elastic diaper side panel 63 is folded at the fold line FW1 68a nearest to the main part 65 in the flat unfolded state, i.e., in the unfolded state, and at the fold line FW1 68b nearest to the closure part 44 or the free end 88 of the second elastic diaper side panel 63 in the flat unfolded state, i.e., in the unfolded state, in each case in the direction of the upper surface 71 of the incontinence disposable diaper 17 facing away from the body, and wherein the second elastic diaper side panel 63 is folded at the middle fold line FW1 68c in the direction of the upper surface 70 of the incontinence disposable diaper 17 facing the body. The reverse orientation of the folds around fold lines 68a, 68b and 68c is also conceivable.Figure 10c shows a second elastic diaper side panel 63 folded in a C-shape around a single fold line FW1 68, wherein the second elastic diaper side panel 63 is folded at the fold line FW1 68 in the direction of the upper surface 71 facing away from the body.
[0348] The disposable incontinence diaper is folded 17 times. The reverse orientation of the fold around the fold line FW1 68 is also conceivable.
[0349] Figure 1 shows a schematic, not to scale, sectional view in the
[0350] Section plane 11 from Figure 3b is shown. The section plane runs in the transverse direction 25 through the double-sided diaper side panel 10, which is provided with a closure element 44 on both sides, i.e., at its first 42 and second diaper side panel edges 43, and is folded on itself in a Z-shape on both sides by two fold lines FW2 50 running parallel to the longitudinal direction 24. The double-sided diaper side panel 10 is shown in a simplified form in Figure 11, namely without marking the overlapping or joining areas of the panels forming the diaper side panel 10.
[0351] Figure 12a shows a schematic, not to scale, sectional view in the
[0352] Section plane 11-12 from Figure 3c. The section plane runs in the transverse direction 74 of the diaper through the back area 64 of the disposable incontinence diaper 17. The absorbent core 69 is located between a backsheet 81a arranged on the side 71 of the disposable incontinence diaper 17 facing away from the body and a backsheet 81a on the side 70 facing the body.
[0353] Incontinence disposable diaper 17 arranged topsheet 80a placed. The first elastic diaper side panel 62 and the second elastic diaper side panel 63 are each provided with a fastening element 44 at their respective free ends 88 and are each folded onto themselves in a Z-shape by two fold lines FW1 68. The first 62 and the second
[0354] Diaper side panel 63 is located between the backsheet 81a arranged on the side 71 of the disposable incontinence diaper 17 facing away from the body and the side panel on the
[0355] The topsheet 80a is arranged on the body-facing side 70 of the disposable incontinence diaper 17 and is permanently connected to the topsheet and / or backsheet in the respective overlap area 87. The topsheet 80a is in this preferred
[0356] Exemplary embodiment formed entirely from a single flat material.
[0357] Figure 12b shows an alternative embodiment of a disposable incontinence diaper 17 as a schematic, non-scale sectional view. The section plane runs through the disposable incontinence diaper 17 in the transverse direction 74. In this variant, the topsheet 80a, located on the body-facing side of the disposable incontinence diaper 17, is formed from three flat material webs 95, 96a, and 96b. The three flat material webs 95, 96a, and 96b are arranged offset from one another in the transverse direction 74 such that the preferably fluid-permeable flat material 95, which is centrally positioned in the transverse direction 74, is sandwiched between a preferably fluid-impermeable first cuff material 96a and a preferably
[0358] The first cuff material 96a and the second cuff material 96b are arranged in a fluid-impermeable second cuff material 96b, wherein the first cuff material 96a and the second cuff material 96b each overlap at least partially with the central flat material 95, and wherein the first cuff material 96a and the second cuff material 96b are in particular permanently connected to the central flat material 95 in the respective joining or overlapping areas. In the thickness direction 27, the three flat material webs 95, 96a and 96b forming the topsheet 80a are arranged such that in the respective joining or overlapping areas, a body-facing upper surface 70 of the central fluid-permeable flat material 95, when the incontinence disposable diaper 17 is worn, is connected to a body-facing upper surface 71 of the first cuff material 96a and the second cuff material 96b.The first 96a and second cuff material 96b each extend beyond the joining or overlapping area towards the other cuff material in such a way that the protruding free areas 97 of the cuff material can function as a lateral leakage barrier of the disposable incontinence diaper 17. In this embodiment, the first 96a and second cuff material 96b are each equipped in the protruding free area 97 with one or more elasticizing agents 98, which support the lifting of the first 96a and second cuff material 96b when worn and their function as a leakage barrier.
[0359] In this embodiment shown in Figure 12b, the liquid-permeable flat material 95 of the topsheet 80a extends in the diaper transverse direction 74 to approximately the same length as the absorbent core 69, and in particular is shorter than the backsheet 81a, with the first cuff material 96a extending to the first rear lateral longitudinal edge 66 and the second cuff material 96b extending to the second rear lateral
[0360] The longitudinal edge 67 of the disposable incontinence diaper 17 extends. In this example, the first elastic diaper side panel 62 and the second elastic diaper side panel 63 are preferably positioned in the thickness direction 27 between the backsheet 81a and the respective first 96a or second cuff material 96b and, in particular, are connected to these in the respective
[0361] Overlap area 87 inextricably connected.
