Description

[Technical Field]

[0001] The present invention relates to an apparatus for producing a nonwoven fabric made of continuous filaments, comprising a spinning device for spinning the filaments and a cooling device for cooling the filaments, a deposition screen belt on which the filaments can be deposited to form a fleece web in a deposition area, the deposition screen belt being deflectable from its conveying direction by at least one nose roller in a deflection area, and at least one subsequent processing device for the fleece web being arranged downstream of the deposition screen belt in the transport direction of the fleece web. The present invention also relates to a method for conveying and processing a fleece web made of continuous filaments. Continuous filaments differ from staple fibers, which have a significantly shorter length, for example 10 to 60 mm, based on their practically infinite length. [Background technology]

[0002] Apparatuses and methods of the type mentioned at the beginning are basically known from practice in various embodiments. In such apparatuses, filaments are spun by a spinning device, subsequently cooled in a cooling device, and finally deposited on a deposition screen belt to form a fleece web. The deposition screen belt of the apparatuses known from practice is usually configured as an endlessly circulating deposition screen belt, which is deflected from its conveying direction by a nose roller in a deflection zone. In this deflection zone, located at the end of the deposition screen belt, the fleece web is transferred from the deposition screen belt or the nose roller to a subsequent processing device, and is therefore peeled from the deposition screen belt in the deflection zone. However, in the apparatuses and methods known from practice, it has been found that peeling the fleece web from the deposition screen belt requires a relatively high force and is not always simple and functionally reliable. Furthermore, since a sufficiently good adhesion of the fleece web to the deposition screen belt is usually desired, at least in the deposition zone, there is an added objective conflict between good peeling properties and sufficient adhesion to the deposition screen belt. Furthermore, particularly in the turning region, the strong turning of the deposition screen belt can cause the deposition screen belt to catch or pinch. As a result, a large force is required to peel the fleece web from the deposition screen belt, and the fleece web can be damaged by filament peeling. In addition, undesirably, filament residues peeled from the fleece web during the peeling process can remain on the deposition screen belt. In this respect, improvement is needed. Summary of the Invention [Problem to be solved by the invention]

[0003] In contrast, the technical problem underlying the present invention is to provide an apparatus of the type mentioned at the beginning, which can simply and reliably peel a fleece web from a depositing screen belt, in particular by avoiding damage to the fleece web during the peeling process and by reducing the effort required to peel the fleece web from the depositing screen belt.Furthermore, the technical problem underlying the present invention is to provide a corresponding method for transporting and processing a fleece web. [Means for solving the problem]

[0004] To achieve this technical objective, the present invention provides an apparatus for producing a nonwoven fabric made of continuous filaments, comprising a spinning device for spinning the filaments and a cooling device for cooling the filaments, a depositing screen belt on which the filaments can be deposited to form a fleece web in a deposition zone, the depositing screen belt being deflectable from its conveying direction by at least one nose roller in a deflection zone, and at least one subsequent processing device for the fleece web located downstream of the depositing screen belt in the transport direction of the fleece web, wherein the fleece web can be peeled from the depositing screen belt upstream of the deflection zone and subsequently delivered to the subsequent processing device.The apparatus according to the present invention is characterized in that at least one lift roller is provided for peeling the fleece web from the depositing screen belt, the lift roller being located or deflectable above the depositing screen belt, and the fleece web can be peeled from the depositing screen belt by the at least one lift roller in a peeling zone located at a distance A from the nose roller.

[0005] The spinning device according to the invention is in particular configured as a spinneret within the scope of the present invention. The conveying direction of the depositing screen belt in the scope of the present invention is in particular the direction in which the depositing screen belt or the endlessly circulating depositing screen belt moves to transport the fleece web. The conveying direction of the fleece web is in particular the conveying direction of the depositing screen belt. The turning area is in particular configured as a spinneret within the scope of the present invention. of Within this scope, the term "peeling zone" refers in particular to the end region of the depositing screen belt, where the depositing screen belt is deflected from its conveying direction by the nose roller and thus leaves the conveying direction. The term "peeling zone" or "peeling zone of the fleece web" refers in particular to the region where the fleece web is peeled from the depositing screen belt. According to a preferred embodiment, the peeling zone is in particular a peeling line extending transversely, preferably perpendicularly, to the conveying direction of the depositing screen belt. The peeling zone or peeling line is preferably arranged upstream of the deflecting zone and / or nose roller in the conveying direction of the depositing screen belt. The distance A is in particular measured between the projection of the rotation axis of the nose roller onto the depositing screen belt and the peeling zone or peeling line, the projection of the rotation axis being perpendicular to the longitudinal extension of the depositing screen belt in the region of the distance A. The longitudinal extension of the depositing screen belt refers in the context of the present invention to its extension in the conveying direction. The deposition zone expediently refers to the region of the depositing screen belt where the spun filaments are deposited to form the fleece web. Here and below, references will be made to operating positions or operating states of the device, unless otherwise stated.

[0006] According to a preferred embodiment of the invention, the device according to the invention is a spunbonding device and is provided with a drawing device for drawing the filaments. Another embodiment of the invention is characterized in that the device according to the invention is a meltblowing device.

[0007] When the apparatus according to the present invention is configured as a spunbond apparatus according to a preferred embodiment, a spunbond fleece or fleece web is produced by the apparatus according to the present invention. In this case, monocomponent and / or multicomponent or bicomponent filaments are produced as continuous filaments. The multicomponent or bicomponent filaments may be, for example, continuous filaments with a core-sheath configuration or continuous filaments with a side-by-side configuration. The multicomponent or bicomponent filaments may have a tendency to crimp. According to a preferred embodiment of the present invention, the continuous filaments produced by the apparatus according to the present invention or the method according to the present invention are made of at least one thermoplastic plastic, in particular at least one polyolefin, preferably polypropylene and / or polyethylene. According to another preferred embodiment, the at least one thermoplastic plastic is a polyester or copolyester, in particular polyethylene terephthalate and / or polyethylene terephthalate copolymer.

[0008] According to the present invention, a cooling device is provided for cooling the filaments. The cooling device preferably comprises a cooling chamber through which the continuous filaments are guided for cooling. Air supply cabins for supplying cooling air are preferably arranged on two opposite sides of the cooling chamber. According to a preferred embodiment, two air supply cabins, one above the other, are present on two opposite sides of the cooling chamber, in particular two air supply cabins arranged one above the other, from which air, preferably at different temperatures, is introduced into the cooling chamber. It has been found that a monomer suction device is provided between the spinning unit and the cooling unit, and by means of this monomer suction device, interference gases arising during the spinning process can be removed from the unit or spunbonding unit. Interfering gases can be, for example, substances such as monomers, oligomers, etc.

[0009] A drawing device for stretching the filaments is expediently arranged downstream of the cooling device in the direction of filament flow. In a particularly preferred embodiment of the device according to the invention, the unit consisting of the cooling device and the drawing device is configured as a closed unit, in which case no additional air is supplied to this closed unit apart from the supply of cooling air to the cooling device.

[0010] Preferably, at least one diffuser is arranged between the drawing unit and the deposition screen belt. The continuous filaments emerging from the drawing unit are guided through the diffuser and then deposited on the deposition screen belt, particularly in the deposition region of the deposition screen belt. According to one embodiment of the invention, two diffusers are provided connected in series. The deposition screen belt or the endlessly circulating deposition screen belt is otherwise expediently configured air-permeable, so that process air can be suctioned from below through the deposition screen belt. Expediently, at least in the deposition region of the deposition screen belt, process air is suctioned through the deposition screen belt by at least one suction device, particularly from below.

[0011] A preferred embodiment of the present invention is characterized in that at least one lift roller is arranged or can be arranged relative to the nose roller so that the peeling region is located upstream of the turning region in the conveying direction of the depositing screen belt. Preferably, at least one lift roller is arranged or can be arranged upstream or downstream of the nose roller in the conveying direction of the depositing screen belt. It is within the scope of the present invention that the fleece web can be or is guided over the at least one lift roller. Preferably, at least one lift roller is configured as a non-suction lift roller.

[0012] In a particularly preferred embodiment of the device according to the invention, the distance A is smaller than the distance C between the nose roller and the deflecting roller. The deflecting roller in this context particularly refers to a roller additionally equipped to the nose roller for transporting the depositing screen belt, which roller is arranged upstream of the nose roller in the transport direction of the depositing screen belt. The deflecting roller is particularly provided between the depositing area and the deflecting area. According to one embodiment, the depositing screen belt can be guided along the deflecting roller without being deflected from its transport direction. In a preferred embodiment, the depositing screen belt is deflected from its transport direction by the deflecting roller, as will be explained in more detail below. It is preferred that at least one nose roller is arranged downstream of the depositing area and downstream of the unit consisting of a blocking device and a cooling device in the transport direction of the depositing screen belt or the transport direction of the fleece web. Expediently, at least one deflecting roller is arranged downstream of the depositing area or downstream of the unit consisting of a blocking device and a cooling device in the transport direction of the depositing screen belt or the transport direction of the fleece web, but upstream of the nose roller. The distance C between the nose roller and the deflecting roller within the scope of the present invention particularly means the distance between the rotation axes of the nose roller and the deflecting roller, which distance is expediently measured between the projections of these rotation axes onto the depositing screen belt, the projections of the rotation axes being perpendicular to the longitudinal extension of the depositing screen belt in the area of ​​the distance C. Expediently, the area between the deflecting roller and the nose roller is a transition area, the length of which is determined in particular by the distance C. Expediently, the transfer table has the function of essentially transferring the fleece web from the depositing screen belt to a subsequent processing device.

[0013] It is particularly preferred that the spacing A is at most 50%, preferably at most 25%, preferably at most 10%, particularly preferably at most 5%, and very particularly preferably at most 2.5%, for example 1%, of the spacing C. According to another preferred embodiment of the device according to the invention, the spacing A is at least 25%, preferably at least 50%, preferably at least 75%, particularly preferably at least 100%, and very particularly preferably at least 125% of the diameter n of the nose roller. Further preferably, the spacing A is 10% to 500%, particularly preferably 25% to 400%, and very particularly preferably 50% to 350% of the diameter n of the nose roller.

[0014] It is within the scope of the present invention that at least one lift roller is height-adjustable relative to the deposition screen belt and, therefore, preferably vertically movable. Preferably, the height-adjustable or vertically movable at least one lift roller can be moved from a basic position to a different lift position and vice versa. In the basic position of the at least one lift roller, for example, cleaning operations of the device can be performed or a fleece web can be threaded, while the device is not in its operating state or position. In the lift position, the at least one lift roller is expediently positioned relative to the nose roller such that, in the operating state of the device, a distance A exists between the peeling area or peeling line of the fleece web and the nose roller.

[0015] A preferred embodiment of the present invention is characterized in that at least one lift roller is configured as a rotary lift roller, in particular as a drivable rotary lift roller. It is also within the scope of the present invention that at least one lift roller is configured as a simple round profile that is non-rotating and non-drivable. Such a round profile has a longitudinal axis instead of a rotation axis. However, preferably, at least one lift roller is configured as a rotary lift roller.

[0016] Another preferred embodiment of the device according to the invention is characterized in that at least one lift roller is arranged or can be arranged at a distance D from the depositing screen belt, which distance D is expediently greater than 50% of the diameter d of the lift roller, preferably at least 55%, particularly preferably at least 60% of the diameter d of the lift roller. Within the scope of the present invention, distance D particularly means the distance of the rotation axis of at least one lift roller from the depositing screen belt, expediently measured perpendicular to the longitudinal extension of the depositing screen belt in the region of the at least one lift roller or an imaginary extension of this longitudinal extension.

[0017] The diameter d of at least one lift roller is preferably 10 to 500 mm, more preferably 25 to 400 mm, more preferably 50 to 300 mm, and particularly preferably 100 to 250 mm. Expediently, the diameter d of at least one lift roller is smaller than 8 times the diameter n of the nose roller.

[0018] An embodiment that is quite particularly important within the scope of the present invention is characterized in that at least two, in particular two, lift rollers are provided, the second lift roller is preferably arranged or can be arranged upstream of the nose roller in the conveying direction of the depositing screen belt, and the first lift roller is preferably arranged or can be arranged between the second lift roller and the nose roller or downstream of the nose roller in the conveying direction of the depositing screen belt.

[0019] Preferably, at least two, in particular two, lift rollers are configured as rotary lift rollers. According to one embodiment, at least two, in particular two, lift rollers are configured as drivable rotary lift rollers. Furthermore, it is within the scope of the present invention that the first and second lift rollers have the same or substantially the same diameter d. However, it is also possible for the first and second lift rollers to have different diameters d1 and d2. In this case, the diameters d1 and d2 are expediently 10 to 50 mm, preferably 25 to 400 mm, preferably 50 to 300 mm, particularly preferably 100 to 250 mm. Preferably, the distance m between the rotation axes of the two lift rollers is at least 105%, preferably at least 110%, particularly preferably at least 115% of the diameter d of the lift roller. If the two lift rollers have different diameters d1 and d2, these notations refer to the diameter of the lift roller with the larger diameter. The rotation axis distance m is expediently measured between the projections of the rotation axes of the lift rollers onto the deposition screen belt, the projections of the rotation axes being perpendicular to the longitudinal extension of the deposition screen belt in the area of ​​the lift rollers. The defect distance m of the two lift rollers is preferably less than 300%, preferably less than 250%, particularly preferably less than 200% of the diameter d of the lift rollers. If the lift rollers have different diameters, these notations relate to the diameter of the lift roller with the larger diameter.

[0020] Both lift rollers are arranged or can be arranged at a distance D or D1 and D2, respectively, from the deposition screen belt, and this distance D1 and / or D2 is preferably greater than 50% of the respective diameter d1 or d2 of the lift roller, particularly preferably at least 55%, and very particularly preferably at least 60% of the respective diameter d1 or d2 of the lift roller.

[0021] According to a variant implementation of the present invention, at least two, in particular two, lift rollers are arranged at the same or substantially the same distance D from the deposition screen belt. In this case, the distances between the rotation axes of the lift rollers and the deposition screen belt are the same or substantially the same. However, it is also within the scope of the present invention for the lift rollers to be arranged at different distances D1 and D2 from the deposition screen belt, in which case the distance D1 of the first lift roller from the deposition screen belt is preferably greater than the distance D2 of the second lift roller from the deposition screen belt. It is within the scope of the present invention that the diameters d1 and d2 of the two lift rollers and the distances D1 and D2 between these lift rollers satisfy the formula D1 + d1 > D2 - d2. Therefore, it is preferred that the sum of D1 and d1 is greater than the difference between D2 and d2.

[0022] It is within the scope of the present invention that the fleece web can be guided over at least one of the lift rollers. When, according to a preferred embodiment of the device according to the present invention, at least two lift rollers, in particular two lift rollers, are provided, the fleece web can be guided expediently under the second lift roller and over the first lift roller. In this connection, it is preferred that the second lift roller is arranged upstream of the first lift roller in the conveying direction of the depositing screen belt. When, according to a preferred embodiment, the fleece web can be guided under the second lift roller and over the first lift roller, the first lift roller is used in particular to peel the fleece web from the depositing screen belt, and the second lift roller is preferably used to hold the fleece web in the vicinity of the depositing screen belt. The insight underlying this embodiment is that, with the second lift roller holding the fleece web in place, a peeling region is arranged or can be arranged in the vicinity of the second lift roller, in particular in the region of the second lift roller. In this way, the distance A from the nose roller can be further limited, in particular to a maximum of 25%, preferably a maximum of 10%, preferably a maximum of 5%, particularly preferably a maximum of 2.5%, and very particularly preferably a maximum of 1%, for example 0.1% of the distance C. Furthermore, the insight behind the use of two lift rollers (the first lift roller is provided for the peeling process and the second lift roller is provided for suppression) is that the peeling area or peeling line can be defined very reliably by the second lift roller. Here, in particular, the distance D2 of the second lift roller from the deposition screen belt has a decisive influence on the distance A of the peeling area or peeling line from the nose roller.In particular, the ratio (D1 / D2) of the distance D1 of the first lift roller to the depositing screen belt and the distance D2 of the second lift roller to the depositing screen belt preferably influences the position of the peeling zone or peeling line such that the larger the wrap angle of the fleece web around the second lift roller, the closer the peeling zone or peeling line is to be located near the intersection of a line extending perpendicular to the depositing screen belt and a line extending through the center point of the second lift roller. It is within the scope of the present invention for the peeling zone or peeling line to be located in the area of ​​the second lift roller, in particular below the second lift roller.

[0023] According to a preferred embodiment of the invention, if at least two, in particular two, lift rollers are provided, both lift rollers are height adjustable relative to the deposition screen belt, so that preferably Tare It is within the scope of the present invention that the lift rollers can be moved in a perpendicular direction. It is possible for both lift rollers to be movable from a basic position to a lift position or to a different lift position and vice versa. In the basic position, cleaning of the device according to the present invention and / or threading of the fleece web are preferably possible. When the device is in an operating state, the lift rollers are expediently arranged in their lift position. In principle, the device can also be operated with the lift rollers in their basic position if stripping of the fleece web by the lift rollers is not required. It is preferred that the first lift roller is arranged below the depositing screen belt in its basic position and / or that the second lift roller is arranged above the depositing screen belt in its basic position. However, in principle, both lift rollers can also be arranged above or below the depositing screen belt in their basic positions.

[0024] It is essentially within the scope of the present invention for the depositing screen belt or transfer table to be arranged parallel or substantially parallel to the foundation or the ground in the operating state of the apparatus. According to a particularly preferred embodiment of the present invention, the nose roller is vertically movable or lowerable. Preferably, the nose roller is vertically movable or lowerable so that the depositing screen belt is oriented in the conveying direction toward the foundation at least between the deflecting roller and the nose roller, preferably with a downward slope of more than 0° to 20°, in particular 3° to 20°, preferably 4° to 18°, and particularly preferably 5° to 16°. When the depositing screen belt has a downward slope toward the foundation, the depositing screen belt is appropriately deflected by the deflecting roller from its conveying direction, which previously ran parallel to the foundation. Vertical nose roller mobility particularly refers to the nose roller mobility toward the foundation and vice versa.

[0025] Another preferred embodiment of the device according to the invention is characterized in that the nose roller is horizontally movable or retractable. In this context, horizontal means, in particular, a direction parallel to the base of the device. Therefore, the horizontal movement or retractability of the nose roller allows the nose roller to be moved, for example, closer to a subsequent processing device. Furthermore, the distance C between the nose roller and the deflecting roller is appropriately increased during movement or retraction and decreased during reverse movement of the nose roller. According to a particularly preferred embodiment, the nose roller is horizontally movable or retractable and vertically movable or lowerable. The insight underlying this embodiment is that the nose roller can be set in the most different positions. For example, a deposition screen belt can be oriented toward the base of the device, and at the same time, the nose roller can be moved closer to a subsequent processing device. If the nose roller is already moving or descending vertically, horizontal mobility or extension also means mobility or extension of the nose roller in the conveying direction of the depositing screen belt, i.e., depending on the downward slope of the depositing screen belt or the downward slope of the transfer table between the deflecting roller and the nose roller.

[0026] According to a particularly preferred embodiment of the invention, if the nose roller is horizontally movable or extendable and vertically movable or lowerable, and if one or both lift rollers are additionally movable vertically, the nose roller can be set in different positions, and both lift rollers can be arranged in their lift position in such a way that the spacing of said rollers from each other and the spacing of the peeling area A from the nose roller are achieved, which spacing and position therefore depend on the operating state of the device.

[0027] It is within the scope of the present invention that the separation area spacing A from the nose roller can be set (also) by the vertical and / or horizontal mobility or stretchability of the nose roller.

[0028] According to one embodiment of the device according to the invention, the nose roller is movable or retractable only in the horizontal direction, but not movable or lowerable in the vertical direction. In this embodiment, the depositing screen belt is arranged parallel or substantially parallel to the device base or the ground, and the nose roller is movable or retractable in the horizontal direction. According to another embodiment of the device according to the invention, the nose roller is neither vertically movable or lowerable nor horizontally movable or retractable, so that there is, so to speak, an inflexible depositing screen belt arranged parallel or substantially parallel to the device base or the ground. Within the scope of these aforementioned embodiments, it is possible that the device does not comprise a deflecting roller. According to a preferred embodiment of the invention, the distance A between the peeling area or peeling line and the nose roller is equal to or greater than the distance A between the nose roller and the depositing screen belt. Compilation The distance A is smaller than the distance E between the deposition area. In the present invention, the distance E is measured in particular between the projection of the rotation axis of the nose roller onto the volume screen belt and the deposition area, in particular the center of the deposition area, the projection of the rotation axis of the nose roller being perpendicular to the longitudinal extension of the volume screen belt in the area of ​​the distance E. The distance A is preferably at most 50%, preferably at most 25%, more preferably at most 10%, particularly preferably at most 5%, and most particularly preferably at most 2.5%, for example 1%, of the distance E. The distance E expediently relates to the state of the device in which the deposition screen belt is arranged parallel or substantially parallel to the device base or the ground, in particular to embodiments in which the device does not have a deflecting roller and / or the nose roller is not vertically movable or lowerable and / or horizontally movable or extendable.

[0029] A particularly important embodiment within the scope of the present invention is characterized in that the subsequent processing device is a consolidation device, in particular a hot air bonder, such as an oven and / or a calender, and / or that the subsequent processing device is a winder. The device can include at least two subsequent processing devices, in particular consolidation devices, in particular a calender and a winder. In this case, the consolidation device or calender is expediently arranged first in the transport direction of the fleece web, and the winder is located downstream of the consolidation device or calender. The consolidation device or calender is particularly used for consolidating or final consolidating the fleece web. Expediently, the fleece web is transferred to the consolidation device or calender after the peeling process in the peeling area.

[0030] It is within the scope of the present invention that the compacting device or calender comprises at least one calender roll, in particular at least one calender roll pair, preferably movable vertically. The fleece web is guided, in particular, through a gap or nip between at least two—preferably arranged one above the other—calender rolls of the at least one calender roll pair. In this case, the fleece web can be guided either so that the calender or at least one calender roll pair is open, so that it does not come into contact with any of the calender rolls, or so that it comes into contact with only one of the calender rolls, for example, in order to influence the properties of the corresponding side of the fleece web, or so that the calender or at least one calender roll pair is closed, so that it comes into contact with both calender rolls. It is also within the scope of the present invention that the fleece web is compacted—in particular by thermal bonding—as it passes between the calender rolls. Particularly preferably, at least three calender rolls are provided for the compaction device or calender, preferably at least one of which is vertically movable, with at least three calender rolls particularly preferably arranged one above the other. This arrangement results in two calender roll pairs, one consisting of the uppermost calender roll and the middle calender roll and the other consisting of the lowermost calender roll and the middle calender roll. The fleece web is guided through one of the resulting gaps appropriately for compaction or final compaction. In this regard, it is within the scope of the present invention that the position of the nose roller and / or lift roller can be set or set depending on the operating mode of the calender. The compaction device or calender preferably has at least one compaction zone in which the fleece web is compacted or final compacted. In this context, a compaction zone refers to a zone in which the fleece web is compacted or final compacted or otherwise processed by interaction or contact with at least one calender roll. It is preferred that the compaction device or compaction zone of the calender be located above the nose roller and / or above the deposition screen belt.In this case, the location of the compaction zone is related to the operating position or operating state of the device.

[0031] It is within the scope of the present invention for the calender to be a compaction calender and / or a coating calender and / or a compensation calender and / or a laminating calender and / or an activation calender.

[0032] The fleece web is preferably peeled off from the depositing screen belt after pre-consolidation of the fleece web. Therefore, the fleece web is preferably pre-consolidated before being peeled off from the depositing screen belt. For this purpose, the apparatus expediently comprises a pre-consolidation device, preferably arranged upstream of the peeling region in the conveying direction of the depositing screen belt. It is possible for the fleece web to be peeled off from the depositing screen belt before final consolidation of the fleece web. However, in principle, the apparatus can also be configured so that final consolidation of the fleece web occurs before the fleece web is peeled off from the depositing screen belt. Such an embodiment in which the fleece web is final consolidation before being peeled off from the depositing screen belt is particularly preferred when the fleece web is subsequently fed directly to a coating calender and / or a correction calender and / or a laminating calender and / or an activating calender and / or a hot air bonder, e.g., an oven.

[0033] Furthermore, it is within the scope of the present invention that at least one lift roller and / or the second lift roller has a distance U from the nose roller, which distance is at least 50% of the diameter of the respective lift roller. The distance U is expediently measured between the projection of the rotation axis of the lift roller onto the volume screen belt and the projection of the rotation axis of the nose roller onto the volume screen belt, the projections of these rotation axes being perpendicular to the longitudinal extension of the deposition screen belt or to an imaginary extension of this longitudinal extension within the distance U. If at least two, in particular two, lift rollers are provided according to a preferred embodiment, both lift rollers preferably have distances U1 and U2 from the nose roller of at least 50% of the diameter of the respective lift roller.

[0034] To achieve this technical objective, the present invention also provides a method for transporting and processing a fleece web made of continuous filaments, in particular by means of the above-described apparatus, in which the fleece web is guided through a depositing screen belt that can be deflected from its transport direction by a nose roller in a deflection region, the fleece web is transferred to a subsequent processing device arranged downstream, and the fleece web is peeled from the depositing screen belt upstream of the deflection region. The method according to the present invention is characterized in that the fleece web is guided through at least one lift roller for peeling from the depositing screen belt, the lift roller is arranged above the depositing screen belt, the fleece web is peeled from the depositing screen belt by the at least one lift roller in a peeling region, the peeling region is arranged at a distance A from the nose roller, and the fleece web is subsequently fed to a subsequent processing device.

[0035] According to a preferred embodiment, the fleece web is subsequently wound up and / or coated and / or corrected and / or activated and / or consolidated in a further processing device.

[0036] The insight underlying the present invention is: BookThe device according to the invention allows functionally reliable and simple peeling of the fleece web from the depositing screen belt, and in particular, reduces the effort required for peeling the fleece web compared to known solutions. This is achieved by peeling the fleece web by at least one lift roller in a peeling zone arranged upstream of the turning zone in the conveying direction of the depositing screen belt. Peeling of the fleece web can be performed by the solution according to the invention, in particular, without damaging the fleece web, for example by tearing the filaments, and therefore without leaving undesirable filament residues on the depositing screen belt. It should also be emphasized that the solution according to the invention is relatively simple and can be implemented without significant effort or cost. When at least two, in particular two, lift rollers are provided according to a preferred embodiment of the invention, the peeling zone or peeling line, and therefore the distance A from the nose roller, can be set very precisely. The preferred vertical mobility of the lift roller and / or the horizontal mobility or telescoping of the nose roller and / or the vertical mobility of the nose roller allows different operating states of the device to be set, in particular the distance of the nose roller to a subsequent processing device, such as a calender, and / or a downward slope of the depositing screen belt to be achieved, while the lift roller can be positioned relative to the depositing screen belt so that the peeling of the fleece web nevertheless takes place or can take place in a peeling zone or peeling line upstream of the turning zone. Thus, the device or the method according to the invention can be used very flexibly and allows a simple and functionally reliable peeling of the fleece web from the depositing screen belt in each case in different operating positions, requiring relatively little effort and, in particular, without damaging the fleece web.

[0037] The invention will now be explained in more detail with reference to the drawings, which show only one embodiment. [Brief explanation of the drawings]

Furthermore, a deposition screen belt 3 is provided, on which the filaments are deposited in the deposition zone. 4 The continuous filaments can be deposited to form a fleece web 5.

Particularly preferably, and in this embodiment (FIG. 4), the distance m between the rotation axes of the two lift rollers 9, 14 is at least 115% of the diameter d of the lift rollers 9, 14 in the operating state of the device. In the illustrated embodiment, the distance m between the rotation axes of the two loft rollers 9, 14 can be approximately 130% of the diameter d of the lift rollers 9, 14. In this connection, the rotation axis distance m means in particular the distance between the rotation axes of the two lift rollers 9, 14, which is expediently measured between the projections of the rotation axes of the lift rollers 9, 14 onto the deposition screen belt 3, the projections of these rotation axes being perpendicular to the longitudinal extension of the deposition screen belt 3 or to an imaginary extension of this longitudinal extension.

[0048] Expediently, in this embodiment, the lift rollers 9, 14 are arranged at a distance D from the depositing screen belt 3. In this connection, the distance D particularly means the distance of the rotation axes of the respective lift rollers 9, 14 from the depositing screen belt 3. In this case, the distance D from the depositing screen belt 3 is expediently measured or determined perpendicularly to the longitudinal extension of the depositing screen belt 3 in the area of ​​the lift rollers 9, 14 or to an imaginary extension of this longitudinal extension. In the illustrated embodiment (particularly FIG. 3), the distance of the first lift roller 9 from the depositing screen belt 3 is designated D1, and the distance of the second lift roller 14 from the depositing screen belt 3 is designated D2.

In the example according to FIG. 2, the depositing screen belt 3 can have a downward slope of approximately 7°, and in the example according to FIG. 3, a downward slope of approximately 15°. The diverting roller 15 thus diverges the depositing screen belt 3 from its conveying direction T, which previously ran in particular parallel to the machine base 11 (FIGS. 2 and 3). In this context, vertical mobility of the nose roller 7 particularly means mobility in the direction of the machine base 11 and vice versa. Even more preferably, and in this example, the nose roller 7 is horizontally movable or extendable. In this context, horizontal means in particular a direction parallel to the machine base 11. The horizontal mobility or retractability of the nose roller 7 allows it to be moved, for example, to the vicinity of the subsequent processing device 8 or the calender 16. Particularly preferably and in this embodiment, the nose roller 7 is horizontally movable or retractable and vertically movable or lowerable, so that the nose roller can be set to different positions.
