- the braking of the known winding device for forcing a correspondingly defined circumferential position after completion of the winding process leads to a high load on the components of the winding device.
- the component load of the winding device is reduced during braking to the conclusion of the winding process when the engagement of the Eingur stresses takes place via a damping element.

- An engaging body 14, at the free end of a hook 15 is formed in the in Fig. 2 shown instantaneous position of the winding device 8 is engaged in a receptacle 16 of the spool wheel 13, which thus represents a receiving body for the Einschreibharm 14.
- the rotational movement of the spool gear 13 with the friction wheel 12 and thus a winding movement of the winding device 8 is stopped.
- the engagement body 14 is elastically damped in the engagement position via a damping element 17 on the receiving body 13.
- the damping element 17 is made of an elastomer and is engaged via a locking foot 18 in a complementary thereto detent receiving the Spulenrades 13 and thereby positively connected thereto.
- the damping element 17 creates when braking the spool 13 via the engaged hook 15 a delay path, which is formed by a compression of the damping element 17 during braking of the spool wheel 13. This delay path leads to a reduction of the braking acceleration of the winding device 8 during braking and thus to a reduced force load when terminating the winding process.
- the engagement body 14 is rigidly connected to a reversing body 19, which has a switching cam with a switching edge 20. Rigid with the Ein WegMI 14 and the Umstelloasa 19 is connected to a trigger lever 21 with a coil-driver surface 22 which rests during winding on a jacket wall of the wound bobbin.

- Fig. 4 shows the rotational position of the coil holder 29 with switched-off bobbin 8, ie before the beginning of the winding process.
- the lovedspulende on the winder shaft 24 thread 10 is already cut to the tear-off 30 and clamped against the spool receptacle 29, so that the thread 10 is held at the beginning of winding.
- Fig. 5 shows the beginning of the winding process, in which the coil holder 29 has performed about one-fifth of a full turn clockwise.
- Fig. 6 shows details for driving the winding device 8.
- the friction wheel 12 acts for this purpose with an end wall 32 of a toothed belt wheel 33 together, which is part of a belt drive of the sewing machine 1.

- the bearing body 35 is in turn connected to the spool wheel 13. In the off position after the Fig.
- Fig. 8 shows a switched-on position of the winding device 8.
- the winding device 8 is switched by pivoting the release lever 21 about the pivot axis 23 such that the hook 15 of the Ein Wegworkss 14 from the receptacle 16 disengages, so that the spool 13 is released from the Einschreibève 14.
- the leaf spring 26 by the switching cam of the Umstell stressess 19 in the Fig. 8 shifted to the top right, so that the leaf spring 26 via the bearing body 35, the spool 13 in the Fig. 8 displaced against the bias of the return spring 27 to the right until the friction wheel 12 comes to rest on the end wall 32 of the toothed belt wheel 33 until the winding device 8 can be driven for winding about the winding axis 25 via the arm shaft 34.
- the thread 10 is wound in the coil housing 31.
- the coil driver surface 22 of the release lever 21 is in contact with the outer jacket wall of the coil formed by the thread 10.

- the free end of the leaf spring 26 is displaced over the switching edge 20 of the reversing body 19 away.
- the leaf spring 26 can thereby relax, so that the tensile force of the return spring 27 in relation to this opposing clamping force of the leaf spring 26 begins to get stronger.
- the leaf spring 26 presses with its free end against the changeover body 19, so that the pivoting movement of the changeover body 19 and thus also the Eingur stresses 14 in the Fig. 7 to 12 continues in a clockwise direction.
- Fig. 11 shows a momentary position of the winding device 8 just before the hook 15 engages in the receptacle 16 of the spool wheel 13.
- the hook 15 is guided by a spiral guide wall 36 of the spool wheel 13. This ensures that the friction wheel 12 is still in frictional connection with the toothed belt wheel 33 until shortly before the end of the winding process.
- Fig. 12 shows the end of the turn-off, so the position of the winding device 8, which, as regards their drive, the position after Fig. 7 equivalent.

Dashed lines is indicated in the Fig. 14 a limitation of a damping layer 38, which is applied to the spool wheel 13, that is on the receiving body, in the region of the receptacle 16.
- the damping layer 3 8 replaces the damping element 17th
- a corresponding damping layer 39 may also be applied to the hook 15, as in FIG Fig. 14 also indicated by dashed lines.
- the selection of the thicknesses of the damping layers 38 and 39 and the choice of material is dependent on the requirements that are placed on a reduction of the acceleration forces during braking of the spool wheel 13 of the winding device 8.
- the damping element 17 or the damping layers 38, 39 may be made of an elastomer, an elastomeric foam or rubber.
- the damping element 17 can also be designed as a resilient element, for example as a leaf spring. A plastic design of such a resilient element is possible.
- the spool wheel 13 may be provided in total from a correspondingly damping or resilient material, so that the damping element is designed with the spool as a one-piece component. Such a one-piece design of the spool wheel 13, which also has the function of the damping element is in the Fig. 12 indicated.

Die Spuleinrichtung muss beim Abschluss des Spulvorgangs in einer definierten Umfangsstellung um die Spulachse stehen bleiben, damit für einen darauf folgenden Spulvorgang eine Anfangsposition zum Festhalten des aufzuspulenden Fadens reproduzierbar vorliegt. Das Abbremsen der bekannten Spuleinrichtung zur Erzwingung einer entsprechend definierten Umfangsposition nach Abschluss des Spulvorgangs führt zu einer hohen Belastung der Komponenten der Spuleinrichtung.A sewing machine of the type mentioned is known by public prior use. The winding device must remain at the conclusion of the winding process in a defined circumferential position about the winding axis, so that there is reproducible for a subsequent winding an initial position for holding the aufzuspulenden thread. The braking of the known winding device for forcing a correspondingly defined circumferential position after completion of the winding process leads to a high load on the components of the winding device.

Dieser Bremsweg führt zu einer erheblichen Verminderung der Kräftebelastung der beteiligten Komponenten beim Abbremsen der Spuleinrichtung. Die Standzeit der Spuleinrichtung ist deutlich erhöht.According to the invention it has been recognized that the component load of the winding device is reduced during braking to the conclusion of the winding process when the engagement of the Einrückkörpers takes place via a damping element. As a result, an increased braking distance is achieved when stopping the rotation of the winding device. This braking distance leads to a significant reduction in the force load of the components involved in braking the winding device. The service life of the winding device is significantly increased.
