Description

[0001] The invention relates to a device for inserting an insert into an insert chamber and a method therefor.

[0002] Devices and methods of the type mentioned above are used to insert an insert into an insert chamber. Entrance mats, particularly those of public facilities, office buildings, shops, or the like, typically have several spaced-apart insert chambers for arranging inserts, such as ribbed inserts for wiping dirt or grime from shoe soles. Inserting one or more inserts is necessary, for example, when initially installing an entrance mat or when replacing soiled or dirty inserts.

[0003] To insert the insert into the insert chamber, it is first necessary to insert it into the chamber. To do this, the insert is inserted manually, for example, by hand, or using an insert insertion device. Known insert insertion devices include, for example, a powered ram, but are cumbersome to handle due to the required power connection and the heavy motor.

[0004] It can therefore be considered an object to provide a device and a method which, with a compact design, enable a simple and reliable change of an insert, in particular a ribbed insert.

[0005] The object is achieved by a device for inserting an insert according to claim 1 and a method for inserting an insert according to claim 15. Dependent claims relate to advantageous embodiments of the invention.

[0006] An insole chamber is understood to be a free area of ​​an entrance mat. The insole chamber usually extends in the longitudinal or transverse direction of the entrance mat. The insole chamber is formed, for example, by a profile and preferably has several insole chambers arranged at a distance from one another and separated from one another by one or more interconnected profiles for accommodating insoles, in particular ribbed insoles. To ensure sufficient contact between a shoe sole and an insole arranged in the insole chamber, the insole chamber has a longitudinal opening extending in the longitudinal axis of the insole chamber. The width of the longitudinal opening is defined, for example, by the distance between two contact surfaces of the profile arranged next to the longitudinal opening.

[0007] An insert describes a strip-like, preferably textile and / or flexible element, for example a ribbed fabric insert, for example a ribbed ribbon. The insert is designed to remove dirt and / or grime deposits from shoe soles. The insert preferably comprises a rib-like fabric with a plurality of projections, for example fibers, nubs, or the like, projecting from a ribbon section. Furthermore, the insert has a first longitudinal edge and a second longitudinal edge arranged at a distance from the first longitudinal edge. The distance between the two longitudinal edges defines the width of the insert. The width of the insert is usually greater than the width of the longitudinal opening of the insert chamber.

[0008] The device according to the invention for inserting an insert into an insert chamber has a base body and a guide space arranged on the base body for guiding the insert in a conveying direction. According to the invention, the device has a first insertion roller which is mounted so as to be rotatable about a first axis of rotation and for pressing the first longitudinal edge of the insert into the insert chamber. Furthermore, the device according to the invention has a pressure roller which is mounted so as to be rotatable about a second axis of rotation and arranged behind the first insertion roller in the conveying direction and for acting on the second longitudinal edge of the insert transversely to the conveying direction. Furthermore, the device according to the invention has a second insertion roller which is mounted about a third axis of rotation and arranged behind the pressure roller in the conveying direction and for pressing the second longitudinal edge of the insert into the insert chamber.According to the invention, the feed rollers and the pressure roller are each arranged at a distance from one another in the conveying direction on the guide space.

[0009] The base body is generally understood to be a component or assembly suitable for arranging the insertion rollers and the pressure roller. The base body is preferably designed for arranging the device on the insertion chamber, in particular on the profile forming the insertion chamber.

[0010] The guide space describes a space in which the insert is guided in the conveying direction when it is inserted into the insert chamber. Guiding is preferably understood to mean that the insert is arranged on and / or in the guide space during operation of the device. The conveying direction describes the direction of movement in which the insert is conveyed, preferably during use of the device, along the guide space and / or the base body relative to the device, preferably along the first insertion roller, the pressure roller and the second insertion roller. To insert the insert into the insert chamber, the device is preferably moved along the insert chamber and / or the insert, such that the insert is preferably conveyed through the guide space relative to the device.Preferably, the guide space is configured and / or arranged on the base body such that the conveying direction is parallel to or in the direction of a longitudinal axis of the base body. Particularly preferably, the guide space for guiding the insert is delimited laterally, in particular transversely to the conveying direction.

[0011] The feed rollers and the pressure roller are each arranged at a distance from one another in the guide space and mounted for rotation about their axes of rotation. The distance between the rollers preferably describes the distance between the respective axes of rotation of the rollers. In the conveying direction, the pressure roller is arranged behind the first feed roller. The second feed roller is arranged behind the pressure roller in the conveying direction, so that the pressure roller is preferably arranged between the feed rollers in the conveying direction.

[0012] Preferably, the first insertion roller is designed and / or arranged on the base body in such a way that the first insertion roller presses the first longitudinal edge of the insert into the insert chamber. The pressure roller is preferably designed and / or arranged on the base body in such a way that the pressure roller acts on the second longitudinal edge of the insert transversely to the conveying direction, i.e. preferably exerts pressure on the second longitudinal edge of the insert transversely to the conveying direction. Preferably, the second insertion roller is designed and / or arranged on the base body in such a way that the second insertion roller presses the second longitudinal edge of the insert into the insert chamber.

[0013] The method for inserting an insert, in particular a ribbed insert, into an insert chamber is carried out in particular with the device described above and comprises the following steps: - guiding the insert in the conveying direction through the guide space arranged on the base body; - pressing the first longitudinal edge of the insert into the insert chamber by means of the first insertion roller which is mounted so as to be rotatable about the first axis of rotation; - acting on the second longitudinal edge of the insert transversely to the conveying direction by means of the pressure roller which is mounted rotatably about the second axis of rotation and arranged behind the first insertion roller in the conveying direction; - Pressing the second longitudinal edge of the insert into the insert chamber by means of the second insertion roller which is mounted so as to be rotatable about the third axis of rotation and is arranged behind the pressure roller in the conveying direction.

[0014] To insert the insert into the insert chamber, the device and the insert are preferably aligned with one another such that the insert is arranged in the guide space for guidance in the conveying direction. The device is preferably moved along the insert chamber and / or the insert so that the insert is particularly preferably brought into contact with the first insertion roller, the pressure roller and the second insertion roller in the conveying direction. The rollers are preferably rotated about their axes of rotation by their respective contact with the insert and in doing so act in different ways on the insert, in particular the longitudinal edges of the insert. Preferably, the first longitudinal edge of the insert is pressed into the insert chamber by the first insertion roller so that the insert is arranged in an inclined position relative to the longitudinal opening of the insert chamber. When the insert is in an inclined position, a distance between the second longitudinal edge of the insert and the insert chamber preferably increases.When acting on the second longitudinal edge of the insert, the pressure roller preferably presses against the second longitudinal edge of the insert transversely to the conveying direction in such a way that the second insert is aligned laterally with the longitudinal opening of the insert chamber and / or is already partially pressed into the insert chamber. Preferably, after being aligned with the longitudinal opening, the second longitudinal edge of the insert is pressed into the insert chamber by the second insertion roller in such a way that the insert is arranged substantially horizontally in the insert chamber.

[0015] The inventors recognized that the insertion rollers arranged on the guide chamber and the pressure roller arranged between the insertion rollers, through their coordinated effect on the insert, enable simple and reliable insertion of the insert into the insertion chamber. Furthermore, the arrangement of the rollers on the guide chamber enables a compact design for the device, eliminating the need for heavy weight and additional power connections, such as those for a nibbler. Furthermore, the rotatable mounting of the rollers allows for easy movement of the device along the insertion chamber.

[0016] According to an advantageous development of the invention, the base body has a first receiving element and a second receiving element arranged at a distance from the first receiving element, wherein the guide space is arranged between the receiving elements. The first and / or the second receiving element are preferably designed for the arrangement of the feed roller and / or the pressure roller. The guide space is arranged between the receiving elements and is preferably formed at least partially by the distance between mutually facing inner surfaces of the receiving elements. Particularly preferably, the feed rollers and the pressure roller are arranged between the receiving elements. The receiving elements are preferably designed as rod-shaped elements. The receiving elements preferably have inner edges extending parallel to the conveying direction for guiding the insert. For example, the receiving elements are designed as strips.

[0017] Preferably, the receiving elements are designed such that the distance between the receiving elements is adjustable. For adjusting the receiving elements, an adjusting element, for example an adjusting screw, is preferably provided on the first and / or second receiving element. By having the base body of the device two receiving elements arranged at a distance from one another, a compact base body for arranging the insertion rollers and the pressure roller can be easily created. The adjustability of the receiving elements relative to one another enables flexible use of the device for inserts and / or insert chambers of different widths, different profile types, and / or different profile spacings.

[0018] According to an advantageous development of the invention, the feed rollers are designed and / or arranged on the base body, in particular the receiving elements, in such a way that the feed rollers each have a diameter that varies transversely to the conveying direction. Preferably, the first feed roller has a cross-section extending in the direction of the first axis of rotation between two end faces. The second feed roller preferably has a cross-section extending in the direction of the third axis of rotation between two end faces. The end faces of the feed rollers each describe the final cross sections of the feed rollers.

[0019] The cross-sections of the rollers, in particular of the feed rollers, can in principle be of any desired design, for example circular, elliptical or polygonal, and can vary in the direction of the rotation axes. For the purposes of the invention, the diameter of the rollers, in particular of the feed rollers, can describe, for example, the diameter of a circular cross-section, the major or minor axis of an elliptical cross-section, or the distance between two adjacent or opposite corner points of a polygonal cross-section. For the purposes of the invention, transverse to the conveying direction is preferably understood to mean a direction arranged at an angle, particularly preferably perpendicular to the conveying direction and / or to the receiving elements, in particular the inner surfaces of the receiving elements.

[0020] In principle, the diameter of the feed rollers can change in any way transverse to the conveying direction. For example, the diameter of a feed roller continuously increases or decreases along the axis of rotation. Furthermore, it is conceivable for the diameter of a feed roller to increase or decrease in steps. An arrangement alternating in the direction of the axis of rotation with a larger and a smaller diameter transverse to the conveying direction is also conceivable. The cross-section of the feed rollers preferably extends between the receiving elements. The diameter of the feed rollers can particularly preferably also be reduced to a value of zero, i.e. the feed rollers are arranged on the receiving elements in such a way that one or both of the end faces of a feed roller are arranged at a distance from the inner surfaces of the receiving elements.Because the feed rollers have a diameter that changes transversely to the conveying direction, different areas of the insert, in particular the first or second longitudinal edge of the insert, can be acted upon even more reliably.

[0021] According to an advantageous development of the invention, the pressure roller is designed and / or arranged on the base body in such a way that the second axis of rotation of the pressure roller is arranged at an angle to a main plane spanned by the first and third axes of rotation of the feed rollers. The feed rollers are preferably arranged on the base body, preferably the receiving elements, in such a way that the first axis of rotation and the third axis of rotation are arranged at an angle, particularly preferably perpendicular to the inner surfaces of the receiving elements. The main plane preferably extends perpendicular to the inner surfaces of the receiving elements. The angle between the second axis of rotation and the main plane is preferably 15 - 90 °, preferably 30 - 85 °, particularly preferably 45 - 80 °, most preferably 60 - 70 °.The pressure roller is preferably arranged on the base body such that the second axis of rotation extends in a secondary plane arranged perpendicular to the main plane. By arranging the pressure roller at an angle to the main plane and / or the insertion rollers, it is easily possible for the pressure roller to push the second longitudinal edge of the insert across the conveying direction and align the insert with the insert chamber during operation of the device.

[0022] Particularly preferably, the pressure roller is arranged on a housing connecting the receiving elements to one another. The housing is preferably connected to the receiving elements via the insertion rollers arranged on the guide space and / or additional connecting elements, for example screws. Preferably, the housing is arranged on the receiving elements in such a way that the guide space in the region of the pressure roller and / or the second insertion roller is delimited by the receiving elements and the housing. Preferably, the housing and / or the second receiving element have a recess for arranging the pressure roller. Particularly preferably, the housing is formed by a first housing half and a second housing half arranged on the first housing half.Preferably, the housing halves are designed such that the housing is divided in the conveying direction, which allows for easy assembly and disassembly of the housing and the pressure roller arranged on the housing during maintenance. For example, the pressure roller is arranged on the second housing half via a bushing in a rotationally fixed manner and is rotatably mounted on the bushing.

[0023] Furthermore, the pressure roller preferably has a cross-section extending in the direction of the second rotational axis. The cross-section of the pressure roller can change in the direction of the second rotational axis. The pressure roller preferably has a circular cross-section and a circumferential surface for contact with the insert. The arrangement of the pressure roller on the advantageously provided housing enables simple assembly and disassembly of the pressure roller for maintenance purposes. Furthermore, the arrangement of the pressure roller in the recess of the housing, in particular the second housing half and the recess of the second receiving element, enables an even more compact design for the device.

[0024] According to an advantageous development of the invention, it is provided that the insertion rollers each have support sections arranged at a distance from one another for rolling on the profile of the insert chamber and a jacket surface arranged between the support sections and acting on the insert.

[0025] The insertion rollers preferably each have a first support section and a second support section. The first support section is preferably arranged closer to the first receiving element and the second support section is closer to the second receiving element. The end faces of an insertion roller are each preferably arranged on the support sections. The first insertion roller and the second insertion roller each preferably have a first end face arranged on the first support section and a second end face arranged on the second support section. The first end face of the insertion rollers preferably each faces a first inner surface of the first receiving element and the second end face of the insertion rollers preferably each faces a second inner surface of the second receiving element."Closer" means that the distance between a support section, in particular between the end faces of the support section, and the respective receiving element is smaller and / or the end face is arranged on the inner surface of the receiving element. For example, the first insertion roller is arranged such that the first support section is closer to the first receiving element and the first end face of the first insertion roller is arranged at a distance from the first inner surface of the first receiving element, and the second support section of the first insertion roller is arranged closer to the second receiving element and the second end face of the first insertion roller is arranged adjacent to the second inner surface of the second receiving element.

[0026] Particularly preferably, the lateral surfaces of the insertion rollers each have a first action region adjacent to the first support section and a second action region adjacent to the second support section. Preferably, the diameter of the first insertion roller is larger in the first action region of the lateral surface than in the second action region of the lateral surface. The diameter of the second insertion roller is particularly preferably larger in the second action region than in the first action region. An action region of the lateral surface adjacent to one support section preferably describes a section of the insertion roller extending from the support section along the axis of rotation of the insertion roller in the direction of the other support section. For example, an action region of the lateral surface of an insertion roller adjacent to the first support section extends along the axis of rotation in the direction of the second support section.

[0027] The support sections of the insertion rollers are preferably formed such that the insertion rollers each roll with their support sections on the profile of the insertion chamber and / or are guided along the insertion chamber. The support sections of an insertion roller preferably have the same diameter. The support sections of the first insertion roller preferably have an inclined support surface for guiding the insertion roller along an outer edge of the profile of the insertion chamber. The support sections of the second insertion roller preferably have a flat support surface for guiding the second insertion roller on the contact surfaces extending parallel to the longitudinal opening of the insertion chamber.

[0028] The advantageous design of the insertion rollers enables targeted pressing in of the first or second longitudinal edge of the insert due to the larger diameter of the action areas on the first or second support section. As the outer surface of the first insertion roller has a larger diameter in the first action area, the first longitudinal edge of the insert is initially pressed into the insert chamber. The second longitudinal edge of the insert, which was previously aligned with the insert chamber preferably by means of the pressure roller, is pressed into the insert chamber via the larger diameter of the outer surface of the second insertion roller in the second action area. Because the insertion rollers each have a smaller diameter in the other action area, undesired action on sections of the insert already arranged in the insert can be avoided.The support sections enable simple and reliable guidance of the device in the longitudinal direction of the insert chamber.

[0029] According to an advantageous development of the invention, the device has a guide element arranged in the guide space for acting on the first longitudinal edge of the insert transversely to the conveying direction. The guide element is preferably designed such that the guide element acts on the first longitudinal edge of the insert transversely to the conveying direction. The guide element preferably aligns the insert with respect to the second insertion roller and / or the longitudinal opening of the insert chamber. The guide element is preferably arranged opposite the pressure roller, for example on the first receiving element or preferably on the housing, in particular on the first housing half. The guide element preferably has an inclined guide surface for acting on the insert. For example, the guide element is designed as a wedge and has a shape that tapers against the conveying direction.The guide element can advantageously counteract any undesirable misalignment of the insert.

[0030] The insert can fundamentally be inserted into the guide space in various ways. For example, the insert is inserted into the guide space manually, for example by a craftsman working with the device. However, according to an advantageous development of the invention, the device has two rotatably mounted guide rollers arranged in front of the first insertion roller in the conveying direction for pre-positioning the insert. The guide rollers are preferably each rotatably mounted about a guide axis. The guide rollers are preferably designed and / or arranged on the base body, in particular the receiving elements, in such a way that the insert is pre-positioned before being pressed into the insert chamber, i.e. is preferably brought into an inclined position relative to the main plane and / or the longitudinal opening of the insert chamber.

[0031] The guide rollers are preferably arranged on a holding element arranged on the second receiving element and particularly preferably protruding into the guide space. The guide rollers are arranged on the holding element such that the guide axes are arranged at an angle, in particular perpendicular to the main plane. The holding element is preferably designed and / or arranged on the second receiving element such that the holding element is adjustable transversely to the conveying direction for displacing the guide rollers. For example, the holding element is arranged via connecting elements in elongated holes arranged on the second receiving element and oriented transversely to the conveying direction.

[0032] The guide rollers are preferably identically formed and arranged point-symmetrically to a plane of symmetry, particularly preferably parallel to the main plane. Further preferably, the guide rollers each have a first conical sub-segment and a second conical sub-segment, so that the insert is preferably pre-positioned by an intermediate space formed between the sub-segments of the guide rollers. The first sub-segment preferably has a larger diameter than the second sub-segment, wherein the sub-segments of a guide roller are each connected to one another via a connecting section of constant diameter. The advantageously provided guide rollers enable an improved starting position of the insert relative to the insert chamber, so that in particular the first longitudinal edge of the insert can be pressed particularly easily into the insert chamber.

[0033] According to an advantageous development of the invention, the device has a holding roller which is mounted so as to be rotatable about a fourth axis of rotation and is arranged behind the first insertion roller in the conveying direction for holding the first longitudinal edge of the insert arranged in the insert chamber. The holding roller is preferably designed and / or arranged on the base body in such a way that the first longitudinal edge of the insert is held in the insert chamber when it acts on the second longitudinal edge of the insert. The holding roller is preferably arranged on the first receiving element and / or the housing, in particular the first housing half. The fourth axis of rotation preferably extends in the main plane or parallel thereto. The holding roller is particularly preferably arranged between the housing halves on the guide element.Further preferably, the holding roller is arranged between the first and second insertion rollers in the conveying direction, and particularly preferably in front of the pressure roller. The holding roller is preferably designed in the shape of a cone and / or a tapered shape. The advantageously provided holding roller can counteract an undesirable change in the position of the insert.

[0034] According to an advantageous development of the invention, the device comprises a correction roller which is mounted rotatably about a fifth axis of rotation and arranged behind the second introduction roller in the conveying direction for adjusting the position of the insert arranged in the insert chamber. The correction roller is preferably designed and / or arranged on the base body in such a way that the position of the insert in the insert chamber is adjusted after the first and second longitudinal edges have been pressed in. The correction roller is preferably arranged on the second receiving element. The fifth axis of rotation preferably extends in the main plane or parallel thereto. The correction roller preferably has a diameter that changes transversely to the conveying direction. The correction roller preferably has a larger diameter in edge regions arranged closer to the receiving elements in order to press the insert against a stop in the insert chamber.With the advantageous correction roller provided, the insert can be positioned particularly reliably in the insert chamber.

[0035] The rollers can in principle be mounted in any desired manner so as to rotate about their respective axes of rotation. Preferably, the rollers are each mounted by means of a bearing element, for example a plain bearing or preferably a roller bearing. According to an advantageous embodiment of the invention, it is further provided that the feed rollers and / or the holding roller and / or the correction roller are each rotatably mounted on shafts extending transversely to the conveying direction, wherein the shafts are each connected in a rotationally fixed manner to the receiving elements. For the rotationally fixed connection of the shafts to the receiving elements, the shafts have external threads which engage, for example, with internal threads arranged on the receiving elements. Alternatively or additionally, securing elements, for example retaining rings, are provided.

[0036] For rotatable mounting of the rollers, roller bearings in the form of needle roller and cage assemblies are provided, for example, on the shafts. Connected to the receiving element means that a shaft is connected to at least one or both of the receiving elements. For example, the shafts of the feed rollers and the pressure roller are connected to both receiving elements, and the shaft of the correction roller is connected only to the second receiving element. Furthermore, the guide rollers and the pressure roller are preferably mounted on the bushing or the holding element via needle roller and cage assemblies. Due to the advantageous arrangement and mounting of the rollers on the shafts, the device can be replaced particularly quickly and easily during maintenance by dismantling the first receiving element.

[0037] According to an advantageous development of the invention, the device has at least one handle arranged on the base body. The handle is preferably designed and / or arranged on the base body in such a way that a craftsman exerts pressure on the receiving elements and thus the insertion rollers and / or the pressure roller and / or the correction roller and / or the holding roller while using the device. The handle is preferably arranged on the housing and particularly preferably connects the two housing halves to one another. Furthermore, the handle is, for example, formed integrally with the housing or is preferably detachably connected to the housing halves, for example by means of additional connecting elements, for example screws. Furthermore, the handle preferably has an arcuate shape to improve the haptics.The handle is generally made of a material of sufficient strength, such as a metal, a plastic, or a composite material. It is conceivable that the handle has a surface coating, for example, made of a plastic such as polyurethane.

[0038] Particularly preferably, the device comprises, in addition to the first handle arranged on the housing, a second handle arranged on each of the receiving elements. The second handle is preferably arranged on the receiving elements as an alternative to the holding element and the guide rollers, or additionally in the region of the guide rollers. Furthermore, the handles are preferably spaced apart from one another in the conveying direction. The handle(s) enable particularly easy operation of the device, so that the user requires less effort to use the device.

[0039] According to an advantageous development of the invention, the device has support rollers arranged on the base body for supporting the base body on the profile surrounding the insertion chamber. The support rollers are preferably designed and / or arranged on the base body in such a way that the receiving rollers support the base body, in particular the receiving elements, on the profile. The support rollers are preferably arranged on the receiving elements, with at least two support rollers being particularly preferably arranged on one receiving element. The support rollers are preferably arranged at a distance from one another in the conveying direction and / or in the longitudinal direction of the receiving elements. Furthermore, the support rollers are preferably arranged on the receiving elements in such a way that the support rollers protrude at least partially from an underside of the receiving elements.For example, the support rollers are arranged rotatably in the receiving elements, penetrating from the top to the bottom of the receiving elements. The advantageously provided support rollers ensure quick and easy adjustment and thus even better operability of the device.

[0040] According to an advantageous development of the invention, the device has at least one positioning roller arranged on the first and / or second receiving element for guiding the base body along a further insert chamber of the entrance mat arranged next to the insert chamber. The positioning roller is preferably rotatably mounted about a positioning axis, wherein the positioning axis is particularly preferably arranged at an angle, in particular perpendicular to the main plane. A needle bearing, for example, is provided for supporting the positioning roller. The positioning roller is preferably designed and / or arranged on the base body in such a way that the positioning roller guides the base body along the further insert chamber, preferably along the longitudinal opening of the further insert chamber, when the device is in use.

[0041] The positioning roller preferably has a diameter adapted to the width of the longitudinal opening such that the positioning roller is only in contact with one longitudinal side of the longitudinal opening when guiding the base body in order to avoid braking on the longitudinal side of the longitudinal opening facing away from the receiving element. Depending on the arrangement of the device on the insertion chamber, the positioning roller is in contact with a different longitudinal edge. The positioning roller is preferably arranged on the first receiving element. Preferably, at least two, preferably at least three, particularly preferably at least four positioning rollers are arranged on the first receiving element at a distance from one another in the conveying direction. By means of the positioning roller(s), the device can be guided particularly reliably and easily along the insertion chamber.

[0042] An embodiment of the invention is explained below with reference to the drawings. In the drawings: Fig. 1 a perspective view of a device for inserting an insert into an insert chamber; Fig. 2 a bottom view of the device of Fig. 1; Fig. 3 a plan view of the device of Fig. 1 and Fig. 2; Fig. 4 a side view of the device arranged for inserting an insert on a profile of an entrance mat of Fig. 1 - 3 with and Fig. 5 a front view of the device arranged on the profile of the entrance mat of Fig. 1 -4 with the insert arranged in the insert chamber.

The insertion rollers 24, 28 and the pressure roller 26 are each arranged at a distance from one another in the conveying direction F on the guide space 22.

[0045] A housing 30 comprising a first housing half 32 and a second housing half 34 is arranged on the base body 16. A handle 36 is connected to each of the two housing halves 32, 34 via a connecting element in the form of screws 38. The two housing halves 32, 34 are further connected to each other via additional screws 37.

[0046] In the guide space 22, a guide element 39, a holding roller 40 mounted rotatably about a fourth axis of rotation D4 and arranged behind the first insertion roller 24 in the conveying direction F, and a correction roller 42 mounted rotatably about a fifth axis of rotation D5 and arranged behind the second insertion roller 28 in the conveying direction F are also arranged. The guide element 39 is, as in Fig. 2, opposite the pressure roller 26, arranged on the first housing half 32.

[0047] Furthermore, in the conveying direction F, two rotatably mounted guide rollers 44 are arranged on a holding element 46 in front of the first feed roller 24.
