- the two outer roller bodies 10 and 12 are driven by the central roller body 11 via a differential gear, so that the two outer roller bodies 10 and 12 with different Rotate speed and one resting on the friction roller 1 conical coil S through the two outer roller bodies 10 and 12 is driven. Since the middle roller body 11 for driving the conical Coil S does not make a significant contribution, only the outer ones Roll body 10 and 12 provided with a friction lining 2, during the middle roller body 11 essentially only the support of the coil S. serves.
- the radius r 1 (FIGS. 4 to 6) of the two outer roller bodies 10 and 12 in the immediate vicinity of the middle roller body 11 is slightly smaller than its radius r 2 (FIG. 1), so that the friction linings 2 of the two roller bodies 10 and 12 due to the differences between these radii r 1 and r 2 are secured axially in the direction of the roller body 11 against axial displacement.
- the two outer roller bodies 10 and 12 each have a ring 100 and 120 on their ends facing the ends of the friction roller 1.
- the friction linings 2 of the two roller bodies 10 and 12 are in the shown Embodiment essentially the same, which is why in the following description only in general on a friction lining 2 Reference is made.
- Such a friction lining 2 shown in FIG. 2, drives the coil S in a frictional manner, sometimes also form-fitting. For this purpose, he points to his Outer peripheral or lateral surface on a surface roughness, which through appropriate choice of materials, shaping or surface processing is achieved.

- the connecting device 3 is composed of two connecting elements 30 and 31 together, of which the connecting element 30 with the end 20th and the connecting element 31 with the end 21 of the friction lining 2 in a suitable manner Is detachably or non-detachably connected.
- the type is one such connection irrelevant.
- Each of the two connecting elements 30 and 31 has a fastening area 300 or 310, which is overlapped by the end 20 or 21 of the friction lining 2 assigned to it in an overlap area I 1 or I 2 . So that the friction lining 2 has a constant thickness over its entire length, each of its two ends 20 and 21 has a correspondingly dimensioned recess 200 and 210 for receiving the fastening area 300 and 310 of the two connecting elements 30 and 31 (FIG. 2 and 4).
- the two ends 20 and 21 of the friction lining 2 are located on the outside of the friction lining 2, which has a ring shape in the closed state, so that the outer surface 23 of the friction lining 2, which is designed as a friction surface, extends to the outermost end region 201 and 211 thereof (see Fig. 4).
- this has a profiling in its fastening area 300 or 310 , with the help of which the connecting elements 30 and 31 not only non-positively, but also form-fitting with the ends 20 and 21 of the friction lining 2 can be connected.

- the two at the ends 20 and 21 of the Friction lining 2 located connecting elements 30 and 31 under tender a pulling force approached each other until their two hooks 305 and 315 by a radial movement in the direction of the one carrying the friction roller 1 Shaft 14 inserted into the recesses 304 and 314 and thereby in mutual Intervention can be brought.
- the hook backs 306 and 316 of the two hooks 305 and 315 are ramp-like.
- the two hooks 305 and 315 with their hook backs 306 and 316 on top of each other run up and slide along it until hooks 305 and 315 are reached of the recesses 304 and 314 snap into them.
- the drive direction f 1 of the friction roller 1 is shown while driving the spool S in its normal winding direction f 2 .
- the two connecting elements 30 and 31 are arranged such that the spool S keeps the two hooks 305 and 315 in mutual engagement while being driven by the friction roller 1. This is the case when, during the drive of the friction roller 1, the connecting element 31 which leads with respect to the direction of rotation and drive f 1 in its area having the hook 315 on the outer circumferential surface 17 (FIGS. 4 to 6) of the roller body 10 or 12 rests. During the acceleration of the coil S, it presses the hooks 305 and 315 into mutual engagement. This does not change if the spool S has reached the same peripheral speed as the friction roller 1. The hooks 305 and 315 are thus acted upon in their closing direction with respect to the drive direction f 1 of the friction lining 2.
- connection between the two ends 20 and 21 of the friction lining 2 can be done in different ways.
- one of the Connecting elements 30 or 31 a bore (not shown) or a itself Axially parallel with respect to the roller body 10 and 12 extending groove (also not shown), with which a correspondingly trained pin or web or a suitably designed rail in engagement can be brought, with an elastic design of this pin or this rail or the hole receiving the pin or the rail receiving groove made the connection in the manner of a clip or can be canceled again.
- connection device 9 has two connecting elements 90 and 91 with Length ranges 900 and 910, which the connection of the two connecting elements 90 and 91 serve each other, as well as attachment areas 901 and 911, which the ends 20 and 21 of the
- the friction lining 2 overlap and can be detached in a suitable manner, for. B. with the help of one or more screws (not shown), or not removable, e.g. B.
- the outer length range in the radial direction 910 of the connecting element 91 has a smooth bore 912, while in the radial direction inner length region 900 a threaded hole 902 has for receiving a screw 40, which on the one hand Part of the connecting device 9 and on the other hand part of the fastening device 4 is.
- this extends as a screw 40 trained fastener only up to a threaded hole 902 in the internal length range in relation to the length range 910 900 of the connecting element 90, but it is also possible - as in FIG. 4 indicated by dashed lines - that the inner length range 900 only has a bore without thread and the screw 40 through both connecting elements 90 and 91 up to a provided in the roller body 10 or 12, recess 101 designed as a threaded bore is sufficient. To this Way, the friction lining 2 is not only due to its tension secured to the roller body 10 or 12, but additionally by Screw 40.
- the friction lining 2 can be removed without any gaps replace later reassembly of the friction roller 1. It is enough, just loosen the screw 40 to remove the friction lining 2 from the roller body To be able to lose 10 or 12.
- the friction lining 2 is pulled on in an analogous manner, as previously described with the aid of FIGS. 2 and 3 only that instead of hooking the connecting elements 30 and 31 here the connection is made using a screw 40.
- the fastening device 4 is not designed as a screw 40, but as a clip element, the recess 101 is adjusted accordingly Trained way.
- a fastening device 4 is provided, so can possibly dispensed with a separate connecting device 3 or 9 become.
- the two open ends 20 and 21 of the Friction lining 2 without the interposition of such a connecting device 3 or 9 with the help of at least one fastening device 4 directly on Roller body 10 and 12 attached.
- the attachment in can be done in different ways. For example, the overlap both ends 20 and 21 of the friction lining 2 (cf. FIG. 4), wherein by appropriate design of these ends 20 and 21, is ensured that the thickness s, which the friction lining 2 outside of its overlap area has, also observed within this overlap area becomes.
- the ends 20 and 21 of the friction lining 2 are brought into mutual contact or at best leave a negligible small gap between them, whereby each of the two ends 20 and 21 by a separate fastening device 4 is attached to the roller body 10 or 12.
- the friction roller 1 is used to drive a cylindrical coil S, so can have an axially longer roller length range for the drive the coil S are used. Accordingly, it is wider in such The same applies to the friction lining 2. If this is made elastic, as in the training described above, which is particularly for the drive conical coils S is suitable, so a large force is required to the friction lining 2 so far that the two connecting elements 30 and 31 by hooking their hooks 305 and 315 together can be.
- the friction lining 2 is stress-free or applied to the friction roller 1 under a low tension and then using a fastening device 4 in the area of the ends 20 and 21 of the friction lining 2 can be secured. It can be provided that the friction lining 2 at a distance from this fastening device 4, d. H. at another point on the circumference of the friction roller 1, using a or several other fastening devices 80, 81 (Fig. 2) on the Rubbing roller 1 is secured.
- the fastening device 4 and the additional Fasteners 80 and 81 as evenly as possible the circumference of the roller body 10 and 12 arranged distributed. If in Fig. 1 also indicated two such fasteners 80 and 81 are, it goes without saying that even a single, essentially opposite from the additional 4 arranged Fastening device may be sufficient; on the other hand can also more than just two additional fastening devices 80 and 81 can be provided.
- FIG. 5 shows a fastening device 5, which works on a different principle than the fastening device 4 shown in FIG. 4.
- the friction lining 6 has on its lateral surface 62 facing away from the roller body 10 or 12 in the region of its two ends 60 and 61 a recess 600 or 610, into each of which a holding surface 50 or 51 of the fastening device 5 extends.
- the two holding surfaces 50 and 51 and the ends 60 and 61 of the friction lining 6 assigned to them are dimensioned such that together they have essentially the same thickness s as the remaining area of the friction lining 6.
- the holding surfaces 50 and 51 are part of a support rail 52, which is supported on the outer peripheral surface 17 of the roller body 10 and 12, respectively.
- the thickness s 1 of the support rail 52 between the holding surface 50 or 51 is slightly less than the thickness s 2 of the end 60 or 61 of the friction lining 6, so that the ends 60 and 61 of the friction lining 6 between the holding surfaces 50 and 51 of the Fastening device 5 and the roller body 10 and 12 are clamped and held by this clamping.
- the roller body 10 or 12 has a T-shaped, axially parallel groove 15, into which the fastening device 5 with a T-shaped Web 53 extends.
- the fastening device 5 is thus in the radial direction due to the undercut of the T-shaped groove 15 in the safe Roll body 10 and 12 held.
- the friction lining 6 is initially outside in the open state the length range of the friction roller 1, d. H. between the friction roller 1 and the holder 13, wrapped around the shaft 14 (Fig. 1). In this Area, the two ends 60 and 61 of the friction lining 6 are each other approached, whereupon the fastening device 5 in the manner between the is brought to both ends 60 and 61 that the two holding surfaces 50 and 51 and the ends 60 and 61 overlap each other. The holding surfaces 50 and 51 can now be released in a suitable manner with the two ends 60 and 61 of the friction lining 6 connected.
- the friction lining 6 now forms with the fastening device a ring and is in this form in the axial direction the roller body 10 or 12 pushed, while the T-shaped Web 53 in the likewise T-shaped groove 15 of the roller body 10 or 12 is introduced.
- the ring 100 or 120 is omitted or it is for the duration of this axial movement of the web 53 during removal and installation of the friction lining 6 temporarily in the radial direction from the friction roller 1 decreased.
- the fastening device 5 is yet another element is assigned, which ensures that the friction lining 6 is not in axial Can shift direction.
- Such an element can, for example, as Screw - similar to that described in connection with FIG. 4 Screw 40 - be formed, which is through the fastening device 5 through into a threaded bore in the roller body 10 or 12 stretched in (not shown).
- the space next to the friction roller 1 is not sufficiently large, it can alternatively be provided while maintaining the ring 100 or 120 that the difference between the radius r 2 of the roller body 11 and the groove 15 which is undercut on the underside of the T-shaped Radius r 3 of the roller body 10 or 12 is dimensioned such that the friction lining 6 brought into the longitudinal region of the roller body 11 can be closed with the aid of the fastening device 5, so that it can then be axially applied to the roller body 10 or 12 can be pushed up to the stop on the ring 100 or 120 while simultaneously inserting the web 53 into the groove 15 of the roller body 10 or 12. Securing against axial displacement of the friction lining 6 in the direction of the center of the friction roller 1 can be done by suitable means in in a manner similar to that previously described.
- FIG. 6 Another embodiment of a friction lining 7 and a fastening device 8 is shown in FIG. 6.
- the ends 70 and 71 of the friction lining 7 have trapezoidal lugs 700 and 710 in this example, their mutually facing end surfaces 701 and 711 in the closed Condition of the friction lining 7 to mutual contact.
- Corresponding the trapezoidal design of the approaches 700 and 710 is in the Roller body 10 or 12 has a dovetail-shaped recess 16 provided, which the trapezoidal approaches 700 and 710 and which is substantially the entire width of the friction lining 7 in its operating position receiving the Roll body 10 and 12 extends.
- the recess 16 thus does not form only one fastening device 8 for the friction lining 7, but also one Connection device for the ends 70 and 71 of the friction lining 7, since this are held in mutual contact by the recess 16, so that the friction lining 7 over the entire circumference of the roller body 10 or 12 stretches.
- the friction lining 7 by axially pushing onto the roller body 10 or 12 with simultaneous insertion of the trapezoidal approaches 700 and 710 pulled into the recess 16, with an additional axial securing can be provided, for example in the form of a screw (see FIG. 4) in each of the two ends 70 and 71 of the friction lining 7 or independently from these ends 70 and 71 or also in the form of a ring 100 or 120 (see Fig. 1).
- the groove or recess 16 can also be in one of the Undercut in a different way (see Fig. 5), the lugs 700 and 710 of the ends 70 and 71 of the friction lining 7 a correspondingly adapted to the shape of the groove or recess 16 Have shape.
- the fastening device 5 or 8 serves not only to fasten the two Ends 60 and 61 or 70 and 71 of the friction lining 6 or 7, but also forms a connecting device in these embodiments. For this reason, when the friction lining 2, 6 or 7 in Area of its both ends 20 and 21, 60 and 61 or 70 and 71 by means of a fastening device 4, 5 or 8 directly on the roller body 10 or 12 is attached, dispensed with an additional, separate connecting device become.
- the friction lining 2, 6 or 7 on the friction roller 1 or their roller body 10 and 12 can have some preforming, d. H.
- the inner peripheral surface 22, 63 or 72 (Fig. 2, 5 and 6) of the friction lining 2, 6 or 7 can have a curvature have, largely already on the curvature of the outer peripheral surface 17 of the friction roller 1 or the roller body 10 or 12 of the friction roller 1 is adjusted.
- the connecting elements 30 and 31 or 90 and 91 of the connection device 3 or 9 the inner peripheral surfaces thereof 307 and 317 or 903 and 913 also such contours can have, which is substantially the circumferential curvature of the outer peripheral surface 17 of the friction roller 1 or its roller body 10 or 12 equivalent. In this way, it requires less effort possible, the friction lining 2, 6 or 7 in the desired end position, the he should take on the roller body 10 or 12 to bring.
- the friction lining 2, 6 or 7 When the friction lining 2, 6 or 7 is stretched, depending on the material selected for this purpose, the case may arise that the friction lining 2, 6 or 7 stretches in different ways over its width. This can be taken into account by the fact that the friction lining 2, 6 or 7 has a correspondingly adapted cross-sectional profile in the untensioned state, in that the friction lining 2, 6 or 7 is made stronger in the middle (see thickness s 3 in FIG. 7) than in FIG its edge areas (see thickness s 4 ), the decrease in cross-section from thickness s 3 to thickness s 4 being gradual, that is to say gradual.
- the decrease in cross-section of the untensioned friction lining 2, 6 or 7 from its maximum thickness s 3 in the middle of the friction lining 2, 6 or 7 to its minimum thickness s 4 in its edge regions is thus based on the tension of the roll body 10 or 12, respectively Friction lining 2, 6 or 7 matched that essentially the difference between the thickness s 3 in the middle of the friction lining 2, 6 or 7 and the thickness s 4 in the two edge regions of the friction lining 2, 6 or 7 is eliminated, ie that the Cross section of the friction lining 2, 6 or 7 is substantially constant over its entire width.
- the exemplary embodiments shown can be supplemented or modified are glued to the two open ends of the friction lining.
- ends can be contrary to the exemplary embodiments shown but only beveled around a particularly firm one and still get a bumpless connection.
- the gluing points can be prepared be a quick assembly with a defined strength of the To create connection.
- the adhesive can be cured quickly by means of light, for example UV light or heat can be activated.
