Patented in the German Empire on April 13, 1916.

The invention relates to a device for winding ring-shaped bodies, in which the wrapping ring is winding toroid is inserted through,> and the purpose of improving and simplifying the facilities known for this purpose. A special device is used to carry the wrapping material in the two devices that have been in use up to now on or on the wrapping rings ι ο 'storage ring or the wrapping material is removed from a roll arranged separately from the winding belt.

However, these devices have the disadvantage that the winding material is very stressful when it is wound onto the toroidal core, since with them the free end of the winding material must pull the supply ring with it. This ^leaves: furthermore, the voltage is not uniform because 'the latter at not quite full inventories. ring is less; than at the beginning of the "winding-up" and therefore the winding material is not evenly fixed around the toroidal core to be wound.

Through the present invention 25-now these evils eliminated while simplifying the whole establishment, since instead In a special supply ring for the wrapping material, the wrapping ring itself is the wrapping; material carries and the latter in the way; to be loaded via a sliding boat; '-winding core: is guided that the ship-J just by means of the wire loop. being towed backwards; üh <i against the turning.

direction of the wrapping ring and against the winding direction of the material towards the coiling ring body. ,,

The shuttle also has, according to the invention, a resilient part which is suitable Changes in the length of the winding material caused by the eccentric position of the material to be wound Toroidal core for wrapping rings arise to compensate. Furthermore, the shuttle is marked with ' A brake spring is provided, which regulates the sliding of the shuttle on the winding ring and thus the tension of the winding material.

The wrapping material slides along the surface of the ring on the wrapping ring led around from the outside to the inside.

The storage of the consisting of two halves The winding ring is carried out by means of bearing rollers pressing against the ring from the outside, which engage in a guide groove of the ring and hold the ring halves together well. Uni a convenient removal of the To achieve the winding ring, one of the bearing rollers is movably arranged. The drive the winding ring is advantageously carried out by means of pulleys, ^ their belts into the same guide groove in which the bearing rollers engage, at a gate of the ring.

The drawing shows an embodiment of the ring wrapping device in FIG. 1 in Side view; Fig. 2 is a side view of one ring half of the wrapping ring with the Shuttle, while Fig. 3 shows the removed

represents little boats seen from the side. In Fig. 4, the shuttle is on Wrapping ring shown in several steps to the wrapping, eccentrically mounted core, All parts that are irrelevant to this have been omitted for the sake of simplicity. At The mode of operation of the device can be clearly understood from this figure. Depending on the tension of the wrapping material g becomes the

The tension spring u of the shuttle I is more or less compressed by the winding material g when sliding on the ring α (first and third position); However, if the shuttle I comes into a position in relation to the body to be wound δ, in which, due to the eccentric position of the body to be wound δ relative to the shuttle I , more winding material g has already been withdrawn than has been used up, as the middle position shows, the excess material g absorbed by the expansion of the tension spring u of the shuttle I and the latter held by the brake spring r on the ring a until this material is used up. After the excess material has been used up, the shuttle I is moved on again by the wrapping material g on the ring α.

The winding ring α expediently has the cross-section shown in FIG. 2 and consists of two halves - ¹ , a ² , in order to be able to insert the ring through the annular body δ to be wound. Held together, the two ring halves are by pins one and corresponding c holes of the other half, and further f through the bearing of the ring in bearing rollers. The ring "has at its outer circumference a small semi-circular groove d, which for guiding the bearing rollers /" and serves to engage the drive belt ζ. Furthermore, it is provided on its outer circumference with a sufficiently large recess e to accommodate the winding material g. In order to give the winding material g leaving the recess 6 of the winding ring α a good sliding surface, the The inner circumference of the winding ring α is provided with a guide groove i and sliding surfaces k for guiding and braking the shuttle / regulating the flow of the winding material g.

The boat I consists of the movably -p in the guide tabs and q of the guide piece t-bearing rod m, t on the guide piece adjustable ν by means of screws arranged, with thread guide w brake spring provided r and connected to these yarns guide plate s. On the with Guide roller η and sliding guide 0 provided rod m is a spring u, which is compressed at the beginning of the winding until the braking spring r slides on the winding ring. Due to the eccentric position of the winding ring to the toroidal core to be wound, a greater length of the wire is already withdrawn than is consumed at one position during the winding process (see Fig. 4), and the above-mentioned spring takes up this greater length of wire. '

When using the device, the opened winding ring α is pushed through the ring body b to be wound and stored in the rollers f of a frame. For this purpose, one of the rollers f is arranged to be pivotable.

Now the wrapping ring receives its wrapping material from a supply roll, from which the material is wound into the recess e , by driving the wrapping ring α in the opposite direction to the later direction of rotation when winding the ring body b. After the winding ring has been provided with sufficient material, the free end of the same, as shown in FIG. 1, is led 85 to the core b to be wound. The latter lies on a table-shaped plate during the winding process, on which it is rotated by suitable devices or by hand.

The winding ring is driven, for example, in the direction of the arrow (clockwise rotation), while the material previously wound onto the winding ring with counterclockwise rotation is applied to the ring body to be wound with clockwise rotation. The shuttle I slides backwards under the influence of the winding wire.

Is z. B. the shuttle .1 in such a position to the ring body b that as a result of the eccentric position of the wrapping ring α to the body 6 to be wrapped no more wrapping material g is removed from the wrapping ring a , but if the wrapping ring were to move on, excess material would be present Shuttle I, the spring u of which has been stretched until now, is held by its brake spring r on the ring α and the excess material g is absorbed by the expansion of the spring u. Middle position of the shuttle in FIG. 4. If the tension increases again due to the consumption of the material g taken up by the spring u of the shuttle I , the tension spring u is compressed and the shuttle I is moved further back by the winding material g on the ring.
