[0079] FIG. 1 shows a view of a bobbin frame 150 of a winding device 100 in a textile machine 700. This can be a spinning machine or a twisting machine. Shown therein is a movable bobbin frame arm 152 and a fixed bobbin frame arm 156 which can be arranged relative to each other to hold a bobbin 110 via a bobbin sleeve 120. The bobbin 110 can be formed in that a thread 122 is wound onto the bobbin sleeve 120. The bobbin 110 is exchanged for an empty bobbin sleeve 120 when a predefined radius of the bobbin 110 is reached. For this purpose, the movable bobbin frame arm 152 can be folded out in an opening direction 154, wherein a sleeve plate 130 can assume a tilted configuration as shown in FIGS. 2A, 4B, 5B, and 6C, and described in this respect. The sleeve plate 130 of the movable bobbin frame arm 152 shown in FIG. 1 is shown in detail in FIGS. 3A and 3B and described in this respect. An identical sleeve plate 130 can be installed in the immobile, fixed bobbin frame arm 156, of which only the sleeve plate rear side 140 or the rear side of its main body 131 can be seen, which can be rotatably mounted on a screw 380.

[0080] FIG. 2A shows a front view of a sleeve plate 230. The sleeve plate 230 has a centering projection 236 which is in particular designed as a cone on which the bobbin sleeve 120 can be received. The conical section (referred to here as the cone) can have a frustoconical lateral surface 237. The thread 122 (not shown here) runs in a gap 232 between the bobbin sleeve 120 and sleeve plate 230. The thread 122 is situated in front of the receiving cone of the sleeve plate 230. During pre-acceleration in a run-up rotational state, the sleeve plate 230 rotates in particular clockwise. The thread 122 (not shown here) is thereby moved downwards on the right-hand side and clamped in the gap 232 between the bobbin sleeve 120 and the sleeve plate 230. Thus, in particular when the bobbin sleeve 120 is pre-accelerated, the thread 122 is entrained. Contact in a contact area, also referred to as contact region 126, between the bobbin sleeve 120 and the sleeve plate 230, as shown in FIG. 2B, can result in a wear region 233. In particular, a wear groove is formed therein, since there is a movement of the bobbin sleeve 120 relative to the sleeve plate 230, which has greater inertial mass, when there is a run-up rotation or pre-acceleration of the bobbin sleeve 120. As a result, the contact region 126, also referred to as a point contact, runs in the wear region (relative movement of the two components, the bobbin sleeve 120 and sleeve plate 130). The wear groove can be formed as a result.

[0081] FIG. 2B shows a side view of a sleeve plate 230 with an arranged bobbin sleeve 120 in a run-up rotational state. The sleeve plate 230 is designed to contact and center a bobbin sleeve 120. This has a centering projection 236 and a main body 231 which is in particular designed to be circular, further in particular is designed plate-like. This has in particular a surface side 133. The centering projection 236 is designed in such a way that it is received by an opening (not shown here) in an end face 124 of the bobbin sleeve 120. The centering projection 236 can be arranged rotationally centered on the surface side 133 of the main body 231 and can project from this surface side 133. In particular, it is designed to center the bobbin sleeve 120 when the bobbin sleeve 120 is in a received state. The centering projection 236 is assigned in particular a frustoconical lateral surface 237, in this case in that the lateral surface of the centering projection 236, which is designed as a cone, directly represents a frustoconical lateral surface 237. This can enable a tilting of a bobbin sleeve 120 for receiving the frustum (i.e. the cone) through an end face opening 125 as shown in FIGS. 4B, 5B, and 6C, enabling the bobbin sleeve 120 to be guided along the inner side 127 (not shown here) until the end face edge 123 of the end face 124 comes into contact with the surface side of the main body 231 for receiving the bobbin sleeve 120.

[0082] FIG. 3A shows an exploded view of a sleeve plate 130 with a wear device 135 which is designed here as a wear ring. The sleeve element 130 can have a wear device 135 on the surface side 133 of the main body 131. A wear region 233 can be arranged therein. The wear device 135 can be designed as a wear ring, as already indicated. As shown in the exploded view in FIG. 3A, the wear device 135 is designed to be arrangeable. The wear device 135 can be embedded in a depression 132 of the surface side 133 of the main body 131 corresponding to the shape of the wear device 135. Alternatively or additionally, the wear device 135 can be designed to be exchangeable.

[0083] Inserting or exchanging can be guided through recesses 146 in the wear ring, which can be brought into engagement with guide elements 134. These recesses and guide elements 134 also allow the sleeve plate 130 to rotate in one piece and, in particular, prevent the wear device from running with a different rotation relative to the sleeve plate 130 during a run-up rotation.

[0084] The sleeve plate 130 can be attached to a rotating body (not shown) via screws 144 in holes 138. In particular, a washer 360 together with a bearing 370 is used for rotation about a screw 380, which serves as a rotation anchor (bearing).

[0085] The wear device 135 serves in particular to be applied to an end face edge 123 of the bobbin sleeve 120 to be received, in a contact region 126, as shown correspondingly in perspective in FIGS. 4B, 5B, and 6C. The wear device 135 can run around the sleeve plate 130 in such a way that, when the bobbin sleeve 120 is in a run-up rotational state, the contact region 126, and thus the wear region 233, remain located in the region of the wear device 135. As a result, it is possible in particular for only the wear device 135 to be exposed to wear-related aging or corresponding consumption.

[0086] FIG. 3B shows a front view of a corresponding sleeve plate 130 with a wear device 135. The wear device 135 and the sleeve plate 130 can be made of different materials, in particular different plastics. Alternatively or additionally, the wear device 135 can be made of either PEEK or PPA. This increases the resistance of the wear device 135 in particular. Alternatively or additionally, the sleeve plate 130 can be made of PA6. This reduces the material costs. The wear device 135 and the sleeve plate 130 can be formed by multi-component injection molding. This makes it possible to combine the different material properties. The wear device 135 can comprise a metallic material, in particular steel. Alternatively or additionally, the wear device 135 can comprise a metallic material sheathed by another material.

[0087] FIG. 4A shows a front view of a sleeve plate 230 with a thread 122, which runs in particular in a gap 232 over a surface of the centering projection 236. In FIG. 4B, an oblique front view of a corresponding sleeve plate 230 is shown with a thread 122 extending in particular in a gap 232 over a surface of the centering projection 236 with a bobbin sleeve 120 in a spinning-on state. In the process, the thread 122 can be entrained by the sleeve plate 230 rotating about the axis of rotation 142, whereby the thread 122 can be wound in a gap 232.

[0088] FIG. 5A shows a front view of a sleeve plate 530 with a thread 122 running in a groove 592 as an exemplary thread guide. FIG. 5B shows an oblique front view of a corresponding sleeve plate 530 with a thread 122 running in a groove 592 with a bobbin sleeve 120 in a spinning-on state. Here, the frustoconical lateral surface 237 is in particular the lateral surface of the centering projection 236, and the frustoconical lateral surface 237 is thus in particular designed and arranged in such a way as to face an inner side 127 of a bobbin sleeve 120 when the bobbin sleeve 120 is in a received state. A thread guide is in particular arranged and designed in a region of the lateral surface in such a way as to guide a thread 122 during a run-up rotation of the bobbin sleeve 120 and to clamp the thread 122 between the end face 124 of the bobbin sleeve 120 and the main body 131 when the bobbin sleeve is in the received state 120.

[0089] In other words, the thread 122 runs through an in particular circumferential groove 592 in the cone (centering cone, centering device, centering projection 536) of the sleeve plate 530, above the clamping area (contact area, contact region 126) between the bobbin sleeve 120 and the sleeve plate 130. When the bobbin sleeve 120 is pre-accelerated, the thread 122 remains in the groove 592 of the rotating sleeve plate 130, in particular above the clamping area, until the gap 232 is closed.

[0090] FIG. 6A shows a front view of a sleeve plate 630 with a thread 122 running in a groove 692 of a collar 690 of a wear device 635. In particular, a wear device can be provided which can serve as an adapter piece for inserting a collar 690 and can enable the outer diameter for different types of bobbin sleeves. In particular, a latching device 634 can also be provided, which allows the collar 690 to latch with corresponding recesses in a centering projection 636.

[0091] FIG. 6B shows a side view of a corresponding wear device 635 in which in particular a collar 690 is formed on a base surface 695 of the wear device 635, and is formed in such a way that, when the wear device 635 is in a mounted state, the collar lateral surface 694 is assigned to the lateral surface of the centering projection 636 as the frustoconical lateral surface 237. The region of the collar 690, which can be arranged on the base side of the centering projection 636, can have an outer diameter which corresponds to the inner diameter of the end face 124 of the bobbin sleeve 120 in order to center the bobbin sleeve 120 in an applied state. In these embodiments as well, the thread guide, in particular formed as a groove 692, can serve as a thread deflecting device.

[0092] FIG. 6C shows an oblique front view of a sleeve plate 630 with a thread 122 running in a groove 692 of a collar 690 of a wear device 635 with a bobbin sleeve 120 in a spinning-on state. The wear device 635 can have a thread guide which is designed here as a groove 692 by way of example. The thread guide, or the groove 692, is designed and arranged so as to receive and guide the thread 122 in a mounted state in order to guide the thread 122 during the run-up rotation of the bobbin sleeve 120 and, when the bobbin sleeve is in the received state 120, to clamp the thread 122 between the end face 124 of the bobbin sleeve 120 and the main body 131.

[0093] The thread guide, here the groove 692 of the wear device 635, can assign a frustoconical lateral surface 237 to the centering projection 636 in such a way that the base surface of the centering projection 636 together with the thread guide arranged on the base surface, here the groove 692, has an outer diameter which corresponds to an inner diameter of the inner side 127 of the end face 124 of the bobbin sleeve 120. As a result, the diameter of the centering projection 636 can be correspondingly adapted in order to be able to receive different bobbin sleeves 120. Alternatively or additionally, it is thereby possible for different thread guides to be providable, which can be adapted to the thread 122 to be guided either in their geometry or also in their material condition and their material properties. As a result, the thread 122 can in particular be guided more gently.

[0094] The thread guide, here the groove 692 of the wear device 635, can in particular be designed exchangeable. Furthermore, the wear device 635 can in particular be designed rotationally symmetrical. The collar 690 can be formed on a base surface of the wear device 635, wherein the groove 692as an example of a thread guide-is formed in the collar 690 in order, in a mounted state, to receive and guide a thread 122 in order to guide the thread 122 during the run-up rotation of the bobbin sleeve 120 and, when the bobbin sleeve is in the received state 120, to clamp the thread 122 between the end face 124 of the bobbin sleeve 120 and the main body 131.

[0095] Can in particular refers to optional features of the invention. Accordingly, there are also developments and/or exemplary embodiments of the invention which additionally or alternatively have the respective feature or the respective features.

[0096] From the combinations of features disclosed in the present case, isolated features can also be taken as needed and used by resolving a structural and/or functional relationship possibly existing between the features in combination with other features for delimiting the subject matter of the claim.
