Description

through a bore 12, which is drawn off via a nozzle 13 under a defined tension. Latter are attached to arms 14, which also carry rollers 15 for the holding wires 11.

On the axis 10, a ratchet wheel 17 is also arranged, with which the winding mandrel 1 with each revolution can be advanced by a certain winding step. The forwarding takes place here Via a spring-loaded pawl 18, which, for example, by a rotating pin 7 with a rotating Switch cam is actuated.

Before the actual winding process, the holding wires 11 are attached to the winding mandrel 1 and tensioned. Thereafter, the winding wire 2 is fixed to one of the holding wires 11 and the device Driven by the pivot pins 6 and 7 about the axis of rotation 5, so that a winding wire layer after the others come to rest on the winding mandrel 1 until the bobbin is finished. After that is the end of the winding wire 2 set and the retaining wires cut or clamped. After removal of the winding mandrel 1 from the arms 8 and 9, the winding can be withdrawn from the winding mandrel 1 and in the usual way Way to be treated further.

The retaining wires 11 remaining in the winding can either be withdrawn from the winding or to be etched out. If a thermoplastic material is used as the retaining wire, this can either remain in the winding or it can be melted out by heating. To the Holding wire feeds, adjustable braking devices are preferably provided to regulate the tension to adjust the retaining wires 11 according to the material used.

1 ■ ■ '. '2', ■ ■ Tubular cross windings with no winding patent claims: heads are mostly made by hand with the help of a winding mandrel, which is 1. The winding device is provided with wire pins arranged in the direction of the winding mandrel, set a tubular, one-piece or multi-piece 5 around which the winding wire is then placed, gen cross winding without winding heads, thereby .. After winding the wire pins are marked out that Jim pulls his axis so that you can get the finished winding from the winding (10) The winding mandrel (1) can be withdrawn step-by-step. Before wrapping a new one During the winding process, such a wobbling loading coil must then be reinserted into the wire pins movement executes that the winding wire (2) io winding mandrel are used. This previously known can be supplied without significant control movement. Production method is cumbersome and time-consuming, so den can, and that at both ends of the winding, that in this way tubular cross windings mandrel diametrically opposite each one on the without winding heads not economically manufactured who-winding mandrel clampable and tangential in the can. Besides, it is not very possible Circumferential direction of the winding mandrel tensioned to produce 15 fine windings, as the wire pins for Holding wire (11) is provided. Holding the winding not made arbitrarily thin 2. winding device according to claim 1, since _r can be. characterized in that the winding mandrel (1). The invention is based on the object, a to create between two each with one of two in the winder, with the in easier Axis of rotation (5) of the winding device against each other 20 tubular cross windings without winding the axially offset pivot pins (6,7) heads can be produced. To do this, one uses connected ^r and diametrically opposite one another in turn a winding mandrel, wherein according to the Arms (8, 9) at a certain angle against the invention of the the axis of rotation (5) is held inclined. switchable winding mandrel during the winding process 3. Winding device according to claim 1 as such a tumbling motion executes that the Wickoder 2, characterized in that the on the lung wire without significant control movement to-winding mandrel (1) clamped retaining wires (11) can be guided, and at both ends of the through a nozzle (13) withdrawn under tension winding mandrel diametrically opposite one on each will. Winding mandrel clampable and tangential in the 4. Winding device according to claim 3, there being tensioned holding through 30 in the direction of the winding mandrel characterized in that the nozzle (13) is provided tan wire. The tumbling movement of the are arranged gential to the winding mandrel (1). Winding mandrel is after a further design 5. Winding device according to one of the anther of the invention in a simple manner thereby ersprüche 1 to 4, characterized in that it is sufficient that the winding mandrel between two each with the winding mandrel (1) after one revolution of 35 one of two in the axis of rotation of the winding device Axis of rotation (5) by more than one wire thickness device axially offset from one another, rotatable indexable is. bolts connected and diametrically opposite- 6. Winding device according to claim 5, that the arms at a certain angle against the characterized in that the indexing axis of rotation is held inclined. With the invention Gearbox and switch cam takes place. 40 according to the winding device can also be multilayered 7. Winding device can be produced according to one of the on-windings. Claims 1 to 6, characterized in that on the basis of one of the steps shown in the drawing Holding wire feeds with adjustable brake guide example, the invention is described below devices are provided. 'described in more detail. It shows . 45 Fig. 1 shows the essential . borrowed part of the winding device, F i g. 2 a winding mandrel with two layers of wire.
With a winding mandrel is referred to, on the one The invention relates to a winding device winding wire 2 to a tubular cross with winding mandrel for producing a tubular winding 3 without winding heads, shaped, one-piece or multi-part cross winding. Tubular cross windings indicated wire feed supplied. So that the DC motors are used, for example, as armature windings for small winding wire without significant control movement, to which the current of the friction roller 4 can be supplied, is supplied via collectors. Such crosses of the invention of the winding mandrel 1 in tumbling windings are also used as a fixed movement offset about an axis of rotation 5. For this standing armature windings with collector and grinding purpose, the two pivot pins 6, 7 with arms 8 are ringless direct current miniature motors. They are then provided and 9, which are bent so that the multi-part, that is, after a certain arms 8 and 9 attached axis 10 of the winding number of turns are when winding wire loops 60 mandrel 1 assumes such an angle that you lead out , so that after the separation of the wire loops with practically no control movement on the winding wire, the individual winding parts come with. This is the case when the cotangent of its one end can be star-connected and, with an angle between the axis 10 of the winding mandrel, its other end can preferably connect to an electrical axis and the axis of rotation approximately equal to the ratio niche commutation device. 65 is from diameter to length of the cross wrap.
