Description

Technical Field

[0001] The present invention relates to an arrangement of unwinding rollers (also called lap-rollers) for a combing machine and a combing machine equipped with the arrangement. Background Technology

[0002] A combing machine is used to comb out unwanted short fibers from a sliver (also called a sliver tangle) wound on a bobbin and combine them into a sliver, which is then fed into a spinning can for further processing into yarn, such as roving. For this purpose, the sliver tangle is arranged on two rows of unwinding rollers (i.e., roller rows). The two rows of rollers rotate and rotate in the same direction. Thus, the sliver wound on the respective sliver tangle can be removed from the associated combing position, combed, and fed to the drafting mechanism, which is typically present in the combing machine, for further processing. The roller rows extend over the entire bridging width of all combing heads and are designed such that each combing position has an associated individual unwinding roller. Therefore, each unwinding roller has a length equal to the bridging width of a combing position. Each unwinding roller is housed at both ends in a corresponding support element of the combing machine in a rotatable manner. All the unwinding rollers of the respective roller rows, arranged in a line, are connected to each other in a twist-resistant manner, for example by means of threaded connections. Each row of rollers is driven by an electric motor at one end. Here, the roller rows are driven to rotate in the same direction via a transmission mechanism such as a belt drive. Each unwinding roller, arranged to prevent twisting, is secured to one shaft on each of the two shafts of each roller row. These two shafts are threaded together at their opposing ends (i.e., the middle of the roller row) and extend through all the unwinding rollers and bearing positions. The unwinding rollers are secured to the resulting continuous shaft by clamping bolts. This frequent support of the shaft by sliding bearings unnecessarily increases the friction that the drive motor must overcome. The drive shaft is continuous, and the four individual unwinding rollers are correspondingly secured to it. The disadvantage is that each roller row has a large number of bearing positions, mathematically equivalent to the following formula:

[0003] n 轴承位置 = 2 n 精梳头 +1; n∈N

[0004] In an 8-head combing machine (n 精梳头In the case of 8), this results in 9 bearing positions per row of rollers or 18 bearing positions for the entire combing machine. Because combing machines tend to have more and more combing heads, this leads to a very large number of bearing positions. Furthermore, these bearing positions are formed using relatively expensive sliding bearings. The reason for using sliding bearings is to prevent the individual unwinding rollers from shifting due to the weight of the placed sliver. In this application, shifting means that the unwinding rollers, supported at both ends, twist about an axis perpendicular to the axis of rotation of the unwinding roller under the load caused by the sliver. Due to the problems with sliding bearings and the large number of bearing positions, the drive motor for the unwinding rollers must apply relatively large amounts of energy. This results in high energy consumption during operation. Moreover, such bearings and unwinding rollers equipped with such bearings are expensive and costly. Summary of the Invention

[0005] The objective of this invention is to address the aforementioned drawbacks.

[0006] This task is solved by an arrangement according to the invention and a combing machine according to the invention.

[0007] This invention provides an arrangement designed for use in a combing machine. This arrangement includes at least one unwinding roller, two support portions, and two bearing units. The two support portions are configured to accommodate the respective ends of an associated unwinding roller among the at least one unwinding roller, allowing the unwinding roller to rotate freely and being anti-misaligned when viewed transversely to its axis of rotation. Anti-misalignment means that when one or more slivers are under load, it prevents or inhibits the unwinding rollers from twisting about an axis perpendicular to their axis of rotation. The two support elements are configured to hold one of the two support portions in a fixed position. That is, the unwinding roller is supported at both ends by the two support portions and can rotate between the two support elements. Here, the length of the unwinding roller is preferably equal to at least one span width of the two combing heads or combing positions of the combing machine viewed along the axis of rotation of the unwinding roller. That is, the unwinding roller according to the invention is constructed to be elongated. Surprisingly, it is not necessary to change, or only minimally necessary to change, the dimensions of such a unwinding roller according to the invention (besides its increased length along the axis of rotation) to further ensure the stability based on the now at least two placed slivers. When a hollow shaft is used as the unwinding roller, its wall thickness does not need to be increased at all or only needs to be increased very little (i.e., at most in the millimeter range). Therefore, the number of supports in the entire arrangement is reduced, thereby reducing the energy consumption for rotating the unwinding roller, which is longer than in the prior art. Alternatively or additionally, anti-misalignment is achieved according to the invention by having at least one support comprising two ball bearings arranged sequentially along the axis of rotation of the accommodated unwinding roller. This pair of ball bearings thus prevents misalignment of the associated end of the associated unwinding roller or the intermediate element fastened thereto. The running resistance of this pair of ball bearings is significantly less than that of a functionally equivalent sliding bearing. That is, the motion resistance of the entire roller arrangement is also reduced by this measure, thereby reducing energy consumption during operation. Therefore, an improved, less frictional, and most importantly, less costly support is obtained by saving bearing positions. Since the unwinding roller can be lengthened, it is not necessary to assemble it on a separate shaft at high cost. Furthermore, in the case of an 8-head combing machine, if the length of each unwinding shaft is equal to the span width of four combing heads, three bearing positions are obtained. In this case, the support portion of the unwinding roller is optionally or additionally constructed with two ball bearings. This can save manufacturing costs.

[0008] At least one support may include a first connecting section. This first connecting section is anti-torsionally mounted on the received end of the associated unwinding roller and configured to be housed in an associated bearing element, allowing free rotation about an axis transverse to the rotational axis of the associated unwinding roller and preventing misalignment. This creates a structural separation between the unwinding roller and the rotating support. This supports the removability of the unwinding roller because the received end of the unwinding roller can be spaced apart from the rotating bearing of the unwinding roller or the end side of the roller bank formed by the unwinding roller and thus "freely suspended" in space.

[0009] In this configuration, at least one first connecting section preferably has a first insert section into which the correspondingly secured end of the unwinding roller is anti-torsionally inserted. The advantage of this solution is that the first insert section forms a practically anti-torsional connection with the associated unwinding roller and is supported independently. Thus, the unwinding roller is partially "suspended" in the air at that end and held in place by means of the arrangement of the first connecting element – ​​the first insert section. This allows the unwinding roller to be removed without affecting the support. Therefore, the bearing positions for the intermediate section are constructed such that the corresponding end facing the unwinding roller serves as a journal pointing from the corresponding support element to the associated unwinding roller. The at least one unwinding roller is fixed between two journals and secured by two clamping couplings serving as the support. Through this modular design, a combing machine can be constructed with more combing heads (e.g., 12 or 16) without using new components.

[0010] This insert section is preferably constructed as a bushing, at least in the associated region of the unwinding roller, having a first top cover. This top cover is placed on the end-bushing arrangement of the associated unwinding roller and is fastened to the rest of the insert section such that the end to be fastened is fixedly and anti-torsively accommodated within the first insert section. This allows the support to be securely mounted in the combing machine, and the installed unwinding roller can be assembled after the combing machine is assembled and can be removed, for example, for cleaning.

[0011] Here, during insertion, a force-locking and / or form-locking engagement can be created or provided between the first insert section and the end to be fastened, thereby ensuring anti-torsion between the first insert section and the associated unwinding roller. Form-locking can be provided such that the unwinding roller has a non-circular outer profile in this region and the first insert section has a preferably complementary inner profile. Therefore, the fastening of the first insert section does not necessarily need to ensure anti-torsion strength, thus allowing for a relatively weak connection between the unwinding roller and the first insert section, such as a detachable locking or threaded connection.

[0012] The aforementioned bearing is advantageously constructed as a grooved ball bearing, which further contributes to energy conservation. The easy mobility of the grooved ball bearing also allows not only one unwinding roller to be driven, but also other unwinding rollers driven by the placed and rotating spool to rotate together.

[0013] Each of the aforementioned arrangements may have at least two unwinding rollers. The two unwinding rollers are arranged with their axes of rotation aligned, thus creating a row of rollers. Between each pair of adjacent unwinding rollers in this row, the arrangement has a coupling. Each coupling includes a connecting section, a connecting support, and a connecting-support element. The connecting section is configured to secure the opposing ends of adjacent unwinding rollers (i.e., an associated pair of unwinding rollers) in a torsion-resistant and misalignment-resistant manner. The connecting section thus transmits rotational motion from one unwinding roller to the other. The connecting support is configured to accommodate the accommodated ends or connecting section of the pair of unwinding rollers in a misalignment-resistant manner, allowing free rotation about an axis transverse to the axis of rotation of the associated pair of unwinding rollers. This provides a misalignment-resistant rotational support for the associated unwinding roller pair-connecting section arrangement. The connecting-support element is further configured to hold the connecting support in a fixed position. Because of the connecting section that can be provided between each pair of unwinding rollers, the unwinding rollers can also be relatively easily removed afterwards, for example, cleaned, and reinserted or replaced. Furthermore, in this arrangement of unwinding rolls in a row of rolls, the same advantages are achieved as with the support portions at the free ends of the roll rows formed in this way, namely the opposite ends of the outermost unwinding rolls of the roll row. Here, the connecting section and connecting support portion can be constructed as described above for the support portion and support element. This increases the number of common parts, which has a favorable impact on manufacturing costs. If one unwinding roll covers, for example, four combing heads, this saves three bearing positions compared to conventional combing machines. Therefore, with this invention, the aforementioned continuous shaft of two rows of rolls is replaced by an extendable, separately constructed unwinding roll that is anti-torsion positioned at the ends, along with two (outer) support portions and one or more connecting sections.

[0014] The anti-displacement property is preferably formed in such a way that at least one connecting support has two ball bearings, which are arranged sequentially along the rotation axis of the housed end of the associated unwinding roller pair, bringing the associated advantages already mentioned.

[0015] The connecting section preferably includes two second connecting sections. According to the invention, each connecting section is fastened or integrally formed on one of the received ends of the unwinding roller pair. This allows the two unwinding rollers to be arranged adjacent to or spaced apart from each other using their opposing ends. This improves the aforementioned removability of the respective unwinding rollers. In particular, the corresponding fastened unwinding roller can be easily removed, similar to the first connecting element, by removing the fasteners at both ends.

[0016] At least one second connecting element may have a second insert section, similar to the aforementioned first insert section, in the form of a bushing that is longitudinally cut at least in the region of the associated unwinding roller, into which the corresponding end of the unwinding roller to be fastened is inserted. A corresponding advantage of this solution is that the second insert section forms an actual anti-torsion connection between the respective unwinding roller pairs and is individually supported. Thus, the unwinding roller at that end is also partially "suspended" in the air and held in place by means of the arrangement of the second connecting element – ​​the second insert section. This allows the unwinding roller to be removed without affecting the support.

[0017] When the end of the associated unwinding roller is inserted into the second insert, a force-locking and / or form-locking engagement can be created or provided between the second insert and the fastened end of the inserted associated unwinding roller, thereby ensuring anti-torsion between the second insert and the associated unwinding roller. The form-locking engagement can be formed similarly to the aforementioned form-locking engagement. That is, the associated unwinding roller has a non-circular outer profile in the region inserted into the second insert, and the second insert has a preferably complementary inner profile. Therefore, the fastening of the second insert does not necessarily need to ensure anti-torsion strength, thus allowing for a relatively weak connection between the unwinding roller and the second insert, such as a detachable lock or threaded connection.

[0018] In both of the last mentioned arrangements, the second connecting section may have a second top cover. According to the invention, the second top cover is mounted on the associated unwinding roller end-bushing arrangement. The second top cover is preferably fastened to the bushing in a manner similar to the first top cover described above, such that the end of the associated unwinding roller to be fastened is anti-torsionally accommodated in and fastened to the second connecting section. The advantage of the second top cover is that it creates a two-piece housing. This facilitates the removal of the associated unwinding roller.

[0019] The combing machine according to the invention has two of the aforementioned arrangements. The two arrangements are configured such that the rotation axes of the unwinding rollers of the two arrangements are parallel and spaced apart, allowing each arrangement to accommodate a corresponding sliver for a corresponding combing head of the combing machine and rotate the sliver by means of the rotation of the unwinding roller carrying the sliver. Furthermore, the combing machine has a drive section. The drive section is effectively connected to the unwinding roller of one of the two arrangements, driving the unwinding roller to rotate. That is, frictional losses and the resulting energy consumption due to the effective connection with the winding roller of the other arrangement can be further reduced. Therefore, the structure of the combing machine is simplified and manufacturing costs are reduced. In addition, the combing machine includes fixing elements, by means of which support elements and connecting-support elements (if present) of the two arrangements are formed. Therefore, regardless of the arrangement according to the invention, the combing machine can be manufactured like any conventional combing machine, only saving the bearing positions for the roller banks or unwinding rollers.

[0020] Here, the rotation axes of the two unwinding rollers in the arrangement are preferably horizontally oriented. This reduces the risk of the spool moving laterally along its rotation axis on the unwinding roller it is positioned on.

[0021] Of course, the drive section can be effectively connected to the two unwinding rollers arranged in the two aforementioned combing machines, rotating and driving these two unwinding rollers. That is, a conventional drive structure is also feasible. This avoids the possibility of modifying existing components of the combing machine. Attached Figure Description

[0044] Figure 1 The frame of an 8-head combing machine 1 according to one embodiment of the invention is shown without a drafting mechanism. For clarity, components not important to the invention, such as the eight combing heads, the fiber unwinding table, and the drafting mechanism of the combing machine 1, which is preferably arranged on the left, are not shown.

[0045] The frame is formed by two lateral frame components 2, with two longitudinal beams 3 extending horizontally between them and mounted on the frame components 2 in a known manner. Thus, the frame for the combing machine 1 is formed in a known manner.

[0046] On the left side of the frame component 2, a support member 19 is provided on the upper side, and a plate 9 is provided on the upper side of the support member. On the right side of the frame component 2, a support member 15 is provided, and a plate 9 is also provided on the upper side of the support member.

[0047] The motor 10 of the drive mechanism 1, which will be described in detail later, can be seen on the right outer side of the support member 15.

[0048] The comb head, not shown, is located here between the two longitudinal beams 3, the comb head fixing and support 8, and another comb head fixing and support 8 or one of the frame components 2.

[0049] On the back side of the rear longitudinal beam 3, there is a fixing and support member 7 in the middle, and there are three fixing members 5 between the member 7 and the plates 9 respectively set on the outer side.

[0050] Guides 6 are exemplarily mounted or integrally formed on the opposing sides of components 5, 7, and plate 9, respectively. Guides 6 are used to restrict the movement of the strip coil disposed therebetween during operation along its axis of rotation, which extends parallel to the longitudinal extension of the longitudinal beam 3. Four unwinding rollers 11 are disposed in the lower region before and after the guides 6.

[0051] Two unwinding rollers 11 of a row of rollers are arranged to prevent each other from twisting in the area of ​​the fixing and support member 7. In this way, two rows of rollers are formed in a front-to-back arrangement, which are mainly formed by two unwinding rollers 11, 11 each.

[0052] A plate-shaped component 4 is present in a known manner behind the arrangement of the unwinding roller 11, through which the strip can move toward the unwinding roller 11.

[0053] The unwinding rollers 11 are arranged in a known manner such that one sliver 11 is placed on each unwinding roller. By rotating the two unwinding rollers, which are arranged one behind the other and belong to two rows of rollers, the corresponding slivers are rotated such that their fiber slivers can be taken out from the associated combing head (not shown) and processed.

[0054] Figure 2 Show Figure 1 The combing machine 1 is partially visible on the back side. It can be seen here that... Figure 1 The row of rollers in the middle and rear is located behind the fixed part 5.

[0055] The fixing and support member 7 is a rotating bearing for the connection between the two unwinding rollers 11 of the respective roller bank, which will be described in detail later.

[0056] The unwinding roller 11 on the left is effectively connected to the motor 10 via a transmission mechanism (described in detail later) provided in the support member 15. That is, the motor 10 can drive the two rows of rollers by rotating the unwinding rollers 11 on the left.

[0057] Figure 3 The frame of combing machine 1 is shown. Figure 1 The left side (i.e.) Figure 1 Partial exploded view of the support portion of the unwinding roller 11 on the left-side fixing member 19.

[0058] Plate 9 is mounted on the upper side of fastener 19. Associated guide 6 is fastened to plate 9. Fastener 19 has a total of two through holes 19a for each unwinding roller 11 to be supported. An arrangement is embedded in each through hole 19a, comprising two spaced-apart ball bearings 14 and a corresponding anti-torsion-received intermediate shaft 13. The outer rings 14b of the two ball bearings 14 belonging to the respective unwinding roller 11 are anti-torsionly disposed in the associated through hole 19a. The intermediate shaft 13 is anti-torsionly disposed in the inner rings 14a of the associated two ball bearings 14 by means of associated bearing sections 13a. Thus, the shaft 13 is anti-misaligned based on the two existing ball bearings 14 spaced apart along the rotation axis of the intermediate shaft 13.

[0059] At the end opposite to the ball bearing 14 (pointing to the right here), each intermediate shaft 13 is anti-torsionally inserted into an associated connecting section 12. Each connecting section 12 is exemplarily constructed as a double-shell bushing, wherein the outer shell extends along the axis of rotation of the intermediate shaft 13. That is, each connecting section 12 includes a top cover 12a, which is mounted on and fastened to the bottom member 12b by means of bolts 12c. The top cover 12a and the bottom member 12b each have a semi-circularly shaped recess in their opposing inner regions, which extends along the axis of rotation or longitudinal extension of the associated intermediate shaft 13. Thus, in Figure 3 In the assembly state shown, a through hole 12d is formed, which is used to anti-torsionly accommodate the right end of the associated intermediate shaft 13 and the protrusion 11a of the corresponding unwinding roller 11 toward the connecting section 12.

[0060] Therefore, in the illustrated example, the intermediate shaft 13 and the protrusion 11a are constructed with circular cross-sections. However, both may also have non-circular cross-sections, or only one may have a non-circular cross-section. Thus, the connecting section 12 preferably has complementary inner contours, so that the intermediate shaft 13 or the protrusion 11a is received in a torsion-resistant manner while being inserted into or moved into the connecting section 12. The bolt 12c only needs to secure the two parts 12a, 12b together, without also applying clamping force to the intermediate shaft 13 and the associated protrusion 11a. When assembling the corresponding unwinding roller 11, the unwinding roller is thus placed on the bottom part 12b, which is simultaneously pressed against the associated intermediate shaft 13 from below.

[0061] The top cover 12a is preferably fixed to the bottom part 12b by means of locking (pre-) and, if necessary, finally tightened to the intermediate shaft 13 and the associated unwinding roller 11 by means of bolts 12c, thereby forming an anti-torsion arrangement of the intermediate shaft 13 relative to the associated unwinding roller 11.

[0062] Figure 4 The frame of combing machine 1 is shown. Figure 1 A partially exploded view of the opposing ends of the unwinding roller 11.

[0063] The fixing and supporting member 7, like the supporting member 19, has a through hole 7a, which has the same function as the through hole 19a in the supporting member 19. That is, similar to... Figure 3 Each through-hole 7a anti-torsionly accommodates two ball bearings 14 spaced apart along the longitudinal extension of the unwinding roller 11 via an outer ring 14b (not shown here). Two intermediate shafts 13 are also anti-torsionly inserted into the corresponding arrangement of the two ball bearings 14. For this purpose, each intermediate shaft 13 has two bearing sections 13a, which are anti-torsionly mounted on the corresponding ball bearing 14 by an associated inner ring 14a (also not shown here).

[0064] and Figure 3 In contrast to the embodiment shown, each intermediate shaft 13 also extends to the left. Therefore, it is possible that, similar to the right end of the corresponding intermediate shaft 13, a connecting section 12 with the same construction as the right-hand connecting section 12 is preferably placed anti-twistfully on the left end of the intermediate shaft 13. Thus, the unwinding roller 11 shown on the left (or its protrusion 11a towards the connecting section) is anti-twistfully positioned with the intermediate shaft 13 via the left-hand connecting section 12, and therefore anti-twistfully positioned relative to the right-hand unwinding roller 11 belonging to the same roller row via the right-hand connecting section 12. This arrangement achieves a axial connection between two adjacent unwinding rollers 11 belonging to the same roller row. Furthermore, each unwinding roller 11 of each row can be individually removed and reassembled, since only the arrangement consisting of the two ball bearings 14 and the intermediate shaft 13 remains in the combing machine 1.

[0065] The advantage of the embodiment shown here is that only the intermediate shaft 13 is constructed differently. All other components are the same as... Figure 3 The corresponding extended portions of the roller rows shown remain the same, which increases the number of available common parts and thus reduces manufacturing costs.

[0066] Here, guides 6 are provided on both sides of the fixing and supporting member 7.

[0067] Figure 5 from Figure 1 The right outer side of the middle is shown in more detail for use Figure 1 The drive mechanism for the unwinding roller 11 on the right side. The support member 15 is presented here such that its internal space is visible. The motor 10 is mounted on the support member 15 such that the free end of its driven shaft is disposed within the internal space of the support member 15. A pulley 16 is provided on the driven shaft in a torsion-resistant manner. Concentrically with the two unwinding rollers 11, an associated pulley 17 is provided in a torsion-resistant manner within the internal space of the support member 15. A belt 18 is wound around pulleys 16 and 17. Therefore, the motor 10 can drive the two unwinding rollers 11 by rotating them in the same direction via pulleys 17 and 17. A sheet 9 is mounted on the support member 15.

[0068] Each pulley 17 is anti-torsionally mounted on an intermediate shaft 13, which in the illustrated example has a recess 13b extending along the axis of rotation of the intermediate shaft 13 or the axis of rotation of the pulley 17 anti-torsionally mounted on the intermediate shaft, and is here constructed as a groove. Thus, the associated pulley 17 is anti-torsionally and positionally fixedly mounted on the associated intermediate shaft 13 via a spring-groove connection.

[0069] Figure 6 Showing the rack Figure 1 A partially exploded view of the support portion of the unwinding roller 11 on the right side of the middle section, and its relationship with... Figure 5 An exploded view of the connection part of the drive mechanism.

[0070] Each unwinding roller 11 is anti-torsively inserted into a connecting section 12 by means of its protrusion 11a facing the motor 10, which is preferably constructed as the previously mentioned connecting section 12. Each connecting section 12 is anti-torsively disposed on an intermediate shaft 13 at its end facing the motor 10. Each intermediate shaft 13 here also includes two bearing sections 13a for anti-torsively accommodating two associated ball bearings 14 by means of an inner ring 14a (not shown here) of ball bearings. Thus, the anti-torsively connected connection between each unwinding roller 11 and the associated intermediate shaft 13 corresponds to the foregoing embodiment. The support member 15, similar to components 7 and 19, has through holes 15a into which two ball bearings 14 belonging to the respective intermediate shafts 13 are anti-torsively inserted by means of their outer rings 14b (not shown here). A plate 9 mounted on the support member 15 carries a guide 6 on its side facing the unwinding roller 11.

[0071] In the illustrated example, each intermediate shaft 13 includes a recess 13b at each end. Each pulley 17 has a through-hole 17a for anti-torsion reception of the associated intermediate shaft 13, into which a stop protrusion 17b extends. Each stop protrusion 17b is preferably formed by means of a resiliently supported pin preloaded toward the through-hole 17a. If the associated intermediate shaft 13 is pushed in, the associated pin 17b is pressed upward by the intermediate shaft 13 due to the recess 13b of the intermediate shaft toward the pulley 17, thus achieving an anti-torsion arrangement of the pulley 17 relative to the associated intermediate shaft 13.

[0072] And intermediate shaft 13 can also be like Figure 4 The structure is as shown. In this case, the intermediate shaft 13 is pushed into the corresponding pulley 17 and clamped. The advantage of the stop protrusion 17b is that when the gear ratio needs to be changed, the pulley 17 can be replaced by another pulley 17. Therefore, except for the different intermediate shaft 13 constructed here, it is preferable to use the same components 12, 14 to anti-torquely position the roller bank, or the unwinding roller 11 facing the motor 10, relative to the motor.

[0073] The present invention is not limited to the embodiments described above.

[0074] Because the present invention only requires the ability to easily remove the unwinding roller 11 in the same assembled state, the connecting section 12 is preferably integrally formed on the associated intermediate shaft 13. Therefore, the bottom part 12b does not need to be laboriously attached to the intermediate shaft 13 and the associated unwinding roller 11 during assembly.

[0075] Alternatively or additionally, the top cover 12a is constructed discontinuously. The top cover 12a extends from one end of the connecting segment 12 toward the associated unwinding roller 11 to approximately halfway along the connecting segment 12. The bottom member 12b thus has a preferably rectangular recess toward the associated unwinding roller 11, into which the top cover 12a fits. Therefore, the connecting segment 12 can be pre-assembled onto the corresponding intermediate shaft 13. When assembling the associated unwinding roller 11, it only needs to be inserted into the opposing ends of the two connecting segments 12. Then, the associated top cover 12a is simply placed and secured to the bottom member 12b by means of two bolts 12c. Locking or clamping between the top cover 12a and the bottom member 12b is also conceivable.

[0076] In this case, the connecting section 12 can also be integrally formed on the intermediate shaft 13. As a result, the fastening elements or fastening sections (such as bolt 12c or locking protrusion) required for the intermediate shaft 13 can be eliminated.

[0077] A clamping connection can also be provided between the intermediate shaft 13 and the associated connecting section 12. This allows the unwinding roller 11 to be easily removed.

[0078] This invention provides a composite component that can be applied to a combing machine having any number of combing heads.

[0079] Instead of two unwinding rollers 11 forming each row of rollers, three or more unwinding rollers 11 can be provided in a row of rollers. Therefore, there are more fixing and supporting elements 7, i.e., one fewer unwinding roller 11 than in each row of rollers. Each unwinding roller 11 also does not need to extend over the bridging width of the four combing heads. Any other length of the bridging width of one or more combing heads is possible.

[0080] Importantly, the unwinding roller 11 is designed to prevent misalignment via components 7, 15, and 19.

[0081] Figure 3 and Figure 4 The intermediate shaft 13 shown in the figure can also have a similar shape. Figure 6 Recess 13b. Alternative site, Figure 6 Each intermediate shaft 13 may also be without a recess 13b.

[0082] In extreme cases, all components 12, 13, and 14, including the anti-torsion arrangement of the unwinding rollers 11, the supports at the free ends of the roller rows that can be formed therein, and the associated drive structure for connecting the combing machine 1, are identical, resulting in low manufacturing costs.

[0083] The protrusion 11a of the unwinding roller 11 can be integrally constructed with the other parts of the unwinding roller 11. Alternatively, it can be constructed using a separate component, which is fixed to the other parts of the unwinding roller 11, for example, by pushing or screwing. If the protrusions 11a on each of the unwinding rollers 11 are constructed identically, the other parts of the unwinding roller can be constructed as a hollow cylinder. This allows such a hollow cylinder to be manufactured from a continuous material, thus simplifying cutting. This also has a favorable impact on manufacturing costs.

[0084] Therefore, the present invention provides an easily operable arrangement that allows the combing machine to be equipped with the unwinding roller 11 in a preferred, energy-efficient, and reliable manner, reducing the number of bearing positions for the unwinding roller 11 compared to conventional combing machines. Another related advantage is that the combing machine can be equipped with significantly more than eight combing heads, resulting in relatively lower operating costs and energy consumption.
