[0002] Title: Driver for a teasel lid rod, lid rod for a teasel and teasel

[0003] Description

[0004] The application relates to a driver for a deck bar of a carding machine according to the preamble of claim 1. The driver comprises a base body with a first fastening means for detachable attachment to the deck bar, a second fastening means for detachable attachment to a drive element, at least one receiving element for detachably receiving a sliding element of the deck bar, wherein the at least one receiving element extends between a contact surface and an outer surface, and an application surface for attaching a cleaning element to the base body, wherein the application surface extends along the at least one receiving element. The application further relates to a deck bar for a carding machine, wherein the deck bar has a support body and at least one sliding element attached to the support body at each end, with a driver arranged at at least one of the end ends.The application also concerns a carding machine with a drum and a traveling cover system with cover rods guided around a partial circumference of the drum.

[0005] When cleaning or carding fibrous materials, such as cotton and / or synthetic fibers, stationary or rotating cleaning or carding elements are typically positioned opposite a rotating drum loaded with a set of cards. To achieve optimal cleaning or carding results, these elements must be positioned as close as possible to the carding set on the rotating drum. This adjustment is made when the drum is cold and stationary. The effective distance between the tips of a carding set and the carding element opposite it is called the carding gap. The carding gap is crucial for carding quality. Its size or width is a machine parameter that influences both the fiber processing technology and the machine's running characteristics, particularly those of a traveling carder, or simply carder. The carding gap is set as narrow as possible without risking collisions between the working elements.To ensure uniform fiber processing, the carding gap must be as consistent as possible across the machine's working width. The carding gap is primarily influenced by the machine settings on the one hand and the condition of the carding unit on the other. To increase card production, the operating speed of the moving elements can be set as high as the fiber processing technology allows. The working gap changes depending on the operating conditions because the carding unit components expand unevenly due to thermal expansion. Consequently, the distances between the drum and the cover, the take-up unit, the fixed covers, and the cutting points with knives decrease. In extreme cases, the set gap (Internal File Reference P249951WOO 17.12.2025 / 2025013723) between the working surfaces can be completely eliminated by thermal expansion, resulting in collisions between moving components.Significant damage to the affected high-performance carding machine is then the result. Furthermore, the generation of heat in the working area of ​​the carding machine can lead to differing thermal expansions if there are excessive temperature differences between the components. To reduce or avoid the risk of collisions, the carding gap between opposing carding sets is set relatively wide in practice, meaning a certain safety margin is maintained. However, a large carding gap leads to undesirable nit formation in the carded strip. An optimal, and especially a consistently narrow, gap size is desirable, as this significantly reduces the number of nits in the carded strip.

[0006] DE 10 2012 006 557 A1 discloses a cover bar for a carding machine, which has a support body with a mounting for a set of components. The support body is assigned two end head sections that slide on a sliding guide and interact with an endless flexible drive element, e.g., a drive belt. A drive element is provided that engages with the support body and the drive element, and the drive element is secured at one end in a recess in the end face of the support body. To ensure that the connection between the cover bar and the drive element is easily detachable, that the drive element is reusable, and that the geometry of the support body is not impaired, the drive element is positively connected to the support body by fasteners that are reversibly detachable.

[0007] EP 3 959 363 B1 discloses a carding machine with a drum and a traveling cover system with cover bars rotating around a partial area of ​​the drum's circumference, wherein at least one cover bar is configured to transmit current operating data or an electrical contact to a carding machine control system, wherein the at least one cover bar is configured to correspond with at least one contact element, wherein the contact element is configured to transmit the electrical contacts or data to the carding machine control system, wherein the at least one contact element is arranged in the area of ​​a flexible arc, wherein the at least one contact element has at least one contact arc configured to compensate for changes in the distance between the cover bar and the drum, so that contact for transmitting data or an electrical contact is always ensured.wherein the at least one contact arc is arranged resiliently or elastically on the contact element.

[0008] Deposits of dust and fiber residue, as well as corrosion on the contact element, can impair electrical conductivity. This can lead to an interruption of the electrical connection between the carding tips of the carding strip and the carding machine's control unit, which is necessary for adjusting the carding gap. Internal file number P249951WOO 17.12.2025 / 2025013723

[0009] One task may be to improve the assurance of electrical contact between the trim strip on the lid rod and the contact element.

[0010] The problem is solved by a driver according to claim 1, a cover rod according to claim 5, and a carding machine according to claim 7. Advantageous embodiments are specified in the respective dependent claims.

[0011] The invention provides that an electrical conductor with at least one contact arm projecting beyond the base body and a contact leg directed towards the receiving element for contacting the sliding element are arranged on the connecting section.

[0012] The arrangement of the electrical conductor with contact arms extending beyond the base body and the contact pins directed towards the receiving element ensures reliable electrical contact with the sliding element. This enables precise transmission of data or electrical information. Integration into the connection section reduces the required installation space and eliminates the need for separate contact elements, simplifying assembly and increasing operational reliability.

[0013] In addition, a robust and durable connection is created, which ensures stable signal transmission even under the dynamic loads of the moving cover circuit.

[0014] The connecting section can project beyond the mounting surface in order to engage, in the installed position, in a fitting receptacle of the cover bar, into which the fitting strip can be inserted in a manner known per se.

[0015] In particular, the cleaning element, when installed with the drive attached to a cover bar and the cover bar inserted into a traveling cover circuit of a carding machine, passes over a sliding strip of the carding machine. The distance between the cover bars and the drum 4, also called the carding gap, can be adjusted using such sliding strips in a manner known per se.

[0016] The driver is designed to be positioned at at least one end of the cover bar, or one driver at each of the two ends of the cover bar. In the installed state, the contact surface of the base body faces a support body of the cover bar. The drive element can be a circulating drive belt. The at least one receiving element for the sliding element can extend from the contact surface to the outer surface facing away from the cover bar and extends in a direction also referred to as the X-direction of a Cartesian coordinate system fixed to the driver or the cover bar. Two receiving elements can be provided, each for one driver, with the application surface being located between the two receiving elements arranged parallel to each other in the X-direction. (See also: Internal file number P249951WOO 17.12.)The dimensions specified in section 2025 / 2025013723 of the drive unit in relation to the cover bar refer to its installation position on the cover bar or its support body, i.e., in the installed state. The base body can be a molded plastic part, for example POM, and can be manufactured as an injection-molded part.

[0017] The cleaning element can be made of materials such as plush, felt, a microfiber-based material, or similar. These materials are durable and particularly well-suited for this application.

[0018] Furthermore, the second fastening element can be designed as a recess for receiving the drive element. The recess can extend through the base body, particularly the base part, thus advantageously facilitating demolding of the base body, which, in a possible configuration, may be a molded part, for example, an injection-molded part. The recess is therefore also continuous through the application surface. The recess can thus extend in a Z-direction of the Cartesian coordinate system fixed to the drive element or the cover rod. A cover can be provided to bridge the recess.With a continuous recess, the base body, produced for example by injection molding, can be demolded. However, the disadvantage is that the adhesive used in the adhesive layer to attach the cleaning element to the application surface comes into contact with the drive element, for example, its cam inserted in the recess, via the recess and impairs it. The cover can therefore be positioned on the side of the second fastener facing the application surface to bridge the gap. Accordingly, the cover can be placed on the second fastener, particularly the recess, before the adhesive layer is applied. The cover advantageously avoids this disadvantage because it separates the adhesive layer from the drive element.The recess can have a step, wherein the recess has a larger cross-section on one side of the step facing the application surface than on the other side, so that the cover can be arranged on the step. The cover can, for example, be cup-shaped or bowl-shaped.

[0019] Furthermore, the first fastening element may be arranged as a cantilever on the base part. The one-piece base body may encompass the first fastening element. Friction plates may be arranged on the cantilever, for example, to increase friction between the cantilever and an opening that receives the cantilever. Additionally or alternatively, the cantilever may have a snap-fit ​​connection at an end remote from the contact surface, wherein the snap-fit ​​connection is, for example, a locking lug designed to engage behind an undercut on the cover bar (Internal File Reference P249951WOO 17.12.2025 / 2025013723).

[0020] Another subject matter of the application relates to a cover bar for a carding machine, wherein the cover bar has a support body and at least one sliding element attached to each end. The driver, as described above, is arranged at at least one of the end ends and detachably connected to the support body by means of the first fastening means. The sliding elements are, for example, cylindrical or pin-shaped. For example, the sliding elements are cylindrical pins and can be referred to as sliding pins. The sliding elements are preferably electrically conductive; for example, the sliding elements are made of metal.

[0021] According to one embodiment, the support body may have a receptacle into which the particularly flexible strip can be inserted. The connecting section of the driver may be arranged in the receptacle such that the contact arm engages in the receptacle. In this way, the contact arm can interact with the strip when it is inserted, for example by contacting a back plate of the strip. The support body may have an undercut, wherein the first fastening element comprises a snap-fit ​​connection element that engages positively with the undercut.

[0022] Another subject matter of the application relates to a carding machine with a drum and cover bars guided around a partial circumference of the drum, wherein at least one cover bar is designed according to one of the embodiments described above.

[0023] The carding machine can have a guide rail and at least one contact element with at least one electrically conductive contact arc on at least one of the two end faces of the moving cover system for guiding the sliding elements of the cover bars, wherein the respective sliding elements are electrically conductive. Preferably, the carding machine has at least one guide rail on each side of the moving cover system. Furthermore, several contact elements can be provided for each guide rail. The contact elements can have contact arcs that, for example, comprise an electrically conductive rail. The sliding elements, which slide over the contact arcs in the carding position of the respective cover bar, then establish the electrically conductive connection between the cover strips and a control unit of the carding machine, which can be connected to the contact arcs via an electrical conductor.

[0024] The sliding elements can each have a sliding section for sliding over the sliding strip and a contact section at their end for sliding over the contact arc, with the application surface extending along the sliding section. Internal file number P249951WOO 17.12.2025 / 2025013723

[0025] Further features and advantages of the subject matter of the application are described in more detail below, together with a description of a preferred embodiment with reference to the figures.

[0026] They show:

[0027] Figure 1 is a schematic sectional view of a carding machine according to the invention;

[0028] Figure 2 is a perspective partial view of the teasel;

[0029] Figure 3 shows a perspective view of a contact element and an embodiment of a cover rod according to the invention;

[0031] Figure 5 shows another perspective partial view of the lid rod according to Figure 3; and

[0032] Figure 6 shows a perspective view of a base body and an electrical conductor attached to it of an embodiment of a driver for the cover rod according to Figure 3;

[0033] Figures 1 to 3 show an embodiment of a carding machine 100 and individual partial views thereof, which are described together below. As shown in Figure 1, in the carding machine 100, fiber flakes are guided via a chute to a feeding roller 1, a feeding table 2, over several pre-tears 3a, 3b, 3c, and to a drum 4. On the drum 4, the fibers of the fiber flakes are parallelized and cleaned by means of stationary carding elements 13 and rotating carding elements, also referred to as carding plates or plate bars 20, arranged on a traveling cover system 17, which can also be called a cover recirculation. For the sake of clarity, only a subset of the plate bars 20 arranged in the traveling cover system 17 are shown in Figure 1; these are transported by means of an endless flexible drive element, for example, a drive belt 25.Arrow B indicates the direction of travel of the cover bars 20 in the carding position within the traveling cover system 17, and arrow C indicates the return transport direction of the cover bars 20. Arrow A indicates the direction of rotation of the drum 4. The resulting fiber web is subsequently conveyed via a take-up roller 5, a stripper roller 6, and several squeeze rollers 7, 8 to a web guide element 9, which forms the fiber web into a fiber ribbon with a hopper 10. The fiber ribbon is then transferred via take-up rollers 11, 12 to a can 15 or a downstream processing machine (not shown), for example, an integrated drafting unit.

[0034] The adjustment of the distance between the cover bars 20 and the drum 4, also called the carding gap, is achieved via a known adjustment mechanism, which is briefly discussed in connection with Figure 2. An embodiment of the adjustment mechanism is shown here, which is described in detail, for example, in German patent application DE 102019 110699 A1. The adjustment mechanism known under internal file number P249951WOO 17.12.2025 / 2025013723 has a slide bar 18, which has an upper, movable, wedge-shaped slide bar 18a and a lower, fixed, wedge-shaped slide bar. The lower slide bar, indicated by reference numeral 18b, can, for example, be integrated into an upwardly open groove of a flexible sheet 27 and is therefore not visible separately in this illustration. For example, the base of the upwardly open groove of the flexible sheet 27 can form or encompass the lower slide bar.To adjust the radius of the slide rail 18 concentrically to the radius of the drum 4 and / or to set the basic distance between the surface of the slide rail 18 and the drum 4, a plurality of adjusting spindles 19 are provided, which can be adjusted manually or by motor, for example with electric motor actuators (not shown). In this embodiment, six adjusting spindles 19 and two adjustment points at the ends are provided, with which the respective slide rail 18 on each side of the carding machine 100 can be adjusted. The adjustment of the upper slide rail 18a on the lower slide rail 18b can be effected with a gear (not shown here) which is driven by an actuator 21, as described, for example, in German patent application DE 102019110654 A1.The actuator 21 can be designed as a motor-gearbox combination, for example as a stepper motor with externally arranged sensors or as a servo motor with integrated sensors. The adjustment or displacement of the upper slide bar 18a on the lower slide bar 18b simultaneously translates the movement due to its wedge shape, as a large distance is covered on the circumference of the lower slide bar 18b, resulting in only a small change in radius. The slide bar 18 is usually mounted directly or indirectly, for example on the flexible bow 27, and can be adjustableally connected to a side plate of the carding machine 100 (not shown here), so that the carding machine 100 can have a flexible bow 27 and at least one slide bar 18 on each side facing the drum 4.

[0035] The radius of the slide bar 18 is thus adjustable or arranged concentrically to the radius of the drum 4, so that the cover bars 20 are guided against the direction of rotation A of the drum 4 during their cover travel in the carding position (see arrow B in Figure 1) and can always maintain the same distance to the drum 4, i.e., the constant carding gap. On the upper surface of the upper slide bar 18a, the cover bars 20 slide with, for example, cylindrical or pin-shaped, sliding elements 38 (Figure 3), which are guided and moved at a distance from each other by the drive belt 25 shown in Figure 1. The electrically conductive sliding elements 38 interact with one or more contact arcs 23 of a contact element 22, which can be arranged, for example, laterally on the slide bar 18 or on the flexible arc 27, as shown in Figure 2.For example, four of the contact elements 22 can be attached to the slide rail 18. The contact arcs 23 can be designed as electrically conductive rails. Each contact element 22 is connected to a control unit 16 of the card 100 by means of an electrical line 64. Internal file number P249951WOO 17.12.2025 / 2025013723.

[0036] Figure 3 shows an exemplary perspective view of one of the contact elements 22 and one of the cover bars 20. Each cover bar 20 has a support body 55, of which only one of two end ends 37 is visible here. A Cartesian coordinate system with X, Y, and Z directions is defined for this figure and for Figure 4 as a coordinate system that moves with the cover bar 20. The support body 55 is an elongated profile in the X direction, in particular made of aluminum. Two of the sliding elements 38 can project from the support body 55 at each end end 37 of the cover bar 20, whereby, in principle, only one of the sliding elements 38 can be arranged at one of the end ends 37. The sliding elements 38 are divided into three functional sections in the X direction. Specifically, the respective sliding element 38 is firmly inserted with its held end in a longitudinal bore of the support body 55, whereby the connection can be reinforced with adhesive if necessary.The two further functional sections of the sliding element 38 are arranged outside the longitudinal bore, wherein, in the carding position of the cover rod 20, a central section, which can also be referred to as the sliding section 34, slides over the sliding strip 18 (see Figure 2) and an end-side, or free-end, contact section 35 interacts with the contact arc 23. Furthermore, a driver 24 is arranged at each of the two head ends 37 of the cover rod 20, which can be pushed or attached onto the respective sliding elements 38.

[0037] The driver 24 for the cover rod 20 has a base body 26, which can be a single-piece component. The base body 26 can be a molded plastic part, for example, made of POM, and can be injection-molded. The base body 26 has a base section 14 that extends in the X-direction between a contact surface 28 facing the support body 55 and an outer surface 44 facing away from it. The surfaces 28 and 44 of the base body 26 can be aligned parallel to each other. The base body 26 has two receiving elements 36 for the sliding elements 38. The receiving elements 36 extend in the X-direction between the contact surface 28 and the outer surface 44. The receiving elements 36 can be shell-shaped and open downwards in the Z-direction, or as shown in Figure 3.In principle, the receiving elements 36 can also be bores formed in the base body 26, which can be penetrated by the sliding elements 38. The base part 14 extends at least substantially along the sliding sections 34 of the sliding elements 38 and is arranged between them. The base body 26 also has a recess extending in the Z-direction as a second fastening means 32 for detachable attachment to the drive belt 25 (see Figure 1). The drive belt 25 can, for example, be an endless belt with projections designed as cams or pin-, peg-, mushroom-shaped, etc., which are inserted into the recesses 32 of the drivers 24. Internal file number P249951WOO 17.12.2025 / 2025013723.

[0038] Figure 4 shows a perspective partial view of the cover rod 20, or the head end 37 of its support body 55, with the driver 24. The support body 55 has a fitting receptacle 56, in a manner known per se, into which a fitting strip 57, in particular a flexible one, can be inserted. Figure 4 shows the cover rod 20 with the fitting strip 57 inserted. The fitting strip 57 can, for example, be magnetically attached to the support body 55, so that it can be easily removed or inserted. For this purpose, a magnetic plate (not shown) can be arranged at the base of the fitting receptacle 56, as in the applicant's product MAGNOTOP, which can interact with a metallic back plate of the fitting strip 57. Other fastening methods, for example by means of clamps or positive locking, are also possible.To simplify the cleaning of the fitting receptacle 56, the drivers 24 are detachably arranged on the head ends 27 of the support body 55.

[0039] Figure 5 shows a further perspective partial view of the cover rod 20, or the head end 27 of its support body 55, with the driver 24. The second fastening element 32, which can also be referred to as a recess, extends through the base body 26, or the base part 14, in the Z-direction. A cover (not shown), which can be inserted before the cleaning element 42 is bonded, can be provided to bridge the recess 32 in order to prevent the drive element 25 from being affected or contaminated by the adhesive layer applied to the application surface 40. The recess 32 can have a step 54, wherein the recess 32 has a larger cross-section on a side of the step 54 facing the application surface 40 than on a side of the step 54 facing away from the application surface 40. The cover can be arranged on the step 54.The cover can be cap-shaped, pot-shaped, cup-shaped, or the like, in particular with a circumferential rim that rests on step 54. For example, the cover is a sealing cap.

[0040] Figure 6 shows a perspective view of the base body 26. The base body 26 has two receiving elements 36 for the sliding elements 38 and a first fastening element 30 with a cantilever arm 39 and a locking connection element 52 designed as a locking lug. The first fastening element 30 comprises the cantilever arm 39 arranged on the base body 26. At the end of the cantilever arm 39 furthest from the contact surface 28, the locking connection element 52 is designed in the form of the locking lug, which interacts with an undercut 58 on the support body 55. When the cantilever arm 39 engages in the undercut 58, it undergoes elastic deformation in the Z-direction, thereby enabling secure locking of the respective driver 24 on the support body 55. With reference to Figure 6, the connecting section 48 of the base body 26 is arranged below or in the Z-direction below the cantilever arm 39.The connecting section 48 is stepped and connects in the Z direction to a side facing away from the cantilever arm 39. Internal file number P249951WOO 17.12.2025 / 2025013723.

[0041] The upper surface 41 is separated from the upper surface 47 of the set strip 57 inserted in the set receptacle 56, see Figure 4. In the foundation 47, for example, U-shaped wire hooks are held, the tips of which form the set tips 29.

[0042] Figure 6 further shows that each driver 24 has an electrical conductor 50 which electrically connects the carding strip 57, when inserted in the carding holder 56, and the sliding elements 38. An electrically conductive connection from the carding strip 57 to the respective contact arc 23 is established via the electrically conductive sliding elements 38 as soon as the respective cover bar 20 is guided along the respective contact element 22 in its carding position and the sliding elements 38 with their contact sections 35 slide accordingly on the respective contact arc 23. The contact elements 22, in turn, are electrically connected to the control unit 16 of the carding machine 100 via their contact arcs 23, which can be designed as electrically conductive rails.Because the drum assembly 31, together with the drum 4 and the trim strip 57 of the cover bar 20, are arranged within the carding machine 100 in an electrically conductive but electrically insulated manner, and an electrical voltage can be applied to both components 31 and 57, an electrical contact is created when the drum assembly 31 touches the trim tips 29 of the trim strip 57 or when they are in very close proximity. This contact is detected and evaluated by the control unit 16 of the carding machine 100 for the purpose of adjusting the carding gap. The control unit 16 evaluates the contacts between the trim tips 29 and the drum assembly 31 with regard to number, duration, and intensity. The control unit 16 can in turn activate individual or all actuators of the adjusting spindles 19, if these are motor-driven, so that the adjusting spindle 19 can pull the flexible arc 27 in or push it away in order to change the carding gap on the traveling cover system 17 segment by segment or completely.

[0043] The electrical conductor 50 is attached to the connecting section 48 to establish the electrical connection between the trim strip 57 and the sliding elements 38, which in turn slide on the electrically conductive contact arc 23 (Figure 3).

[0044] The electrical conductor 50 is fully visible in Figure 6. A contact arm 60 of the electrical conductor 50, located on the assembly side, projects beyond the connecting section 48 and beyond the entire base body 26. In the installed position, as shown, for example, in Figure 6, this arm projects into the assembly receptacle 56 to contact the assembly strip 57 on an underside facing away from the assembly tips 29, for example, on its metallic backplate. Two contact pins 61 of the electrical conductor 50 are arranged in the area of ​​the two receiving elements 36, here extending from the receiving elements 36, to contact the sliding elements 38. A base section 49 of the electrical conductor 50 connects the contact arm 60 and the contact pins 61 to each other.In the embodiment shown here, the contact arm 60 on the fitting side extends from the base section 49 in a first direction and the two contact legs 61 extend from the base section Internal file number P249951WOO 17.12.2025 / 2025013723.

[0045] 49 in an opposite direction, wherein the assembly-side contact arm 60 and one of the two contact legs 61 can be arranged in extension to each other. It is also possible that a second assembly-side contact arm 60 is arranged in extension to the other of the two contact legs 61. The contact arm 60 and / or the contact legs 61 can be resiliently designed. The electrical conductor 50, in particular the base section 49, is attached to the connecting section 48 via at least one fixing point 65, here two fixing points 65.

[0046] The design and function of the drive unit 24 can be viewed from both sides of the

[0047] The cover rod 20 must be identical. It is possible to have a "left" driver 24 and a "right" driver 24, since the sliding elements 38 in the respective cover rod 20 may be arranged at slightly different heights, particularly along the Z-axis, or only one of the sliding elements 38 may be provided at one of the head ends 37. Accordingly, the arrangement and design of the respective receiving element 36 in the driver 24 may also differ slightly.
