The invention relates to a device for driving the Thread guide of a winding machine or the like.

A conventional winder generally includes one drivable spindle, also called winding mandrel, onto which the threads are wound, which via a thread guide comb existing thread guide are guided on a carriage is arranged, which is parallel to the drivable spindle j can be moved back and forth in a straight line. ;

In the case of large spindle lengths, difficulties arise when driving the slide, because the conventional drive means, such as chains, have proven to be imprecise, heavy and difficult to handle. In addition, the spindle lengths are variable and the consequently necessary chain replacement is time-consuming.

It is also desirable that the speed reversal of the carriage at each end of its travel path progressive and ^ takes place according to a certain law that depends on the angle of inclination and the diameter of the spindle.

The invention is based on the object of providing a simple and inexpensive device for driving the carriage which not only has the aforementioned disadvantages eliminated, but also changing the winding direction and the necessary speed range under optimal conditions.

A device that achieves this object according to the invention is characterized by at least one endless, over two j with pin or the like. provided wheels tensioned, parallel to the

Direction of movement of the carriage arranged metal band, such as steel band, and by a entrainment member on the one hand fixed on the metal band and on the other hand with a support of the slide opposite this in the vertical direction

t is slidably connected, so that the support carried along the Transferring movement of the metal band to the carriage.

According to one embodiment of the invention Device with a single metal band, the entrainment member consists of one on the metal band around one perpendicular to the Belt level · standing axis rotatably fixed arm and from / an auxiliary slide which is vertically displaceable within the slide support, in which this arm rotates around a horizontal one Axis is rotatably mounted so that the metal strip is not subjected to any torsional stress.

Hich another exemplary embodiment of the invention Device in which two metal straps arranged parallel to one another are provided, the support of the slide runs in a vertical plane between the metal bands back and forth forth and has a vertical slot in which the two pin parts and a hollow shaft existing entrainment member up and down, the two pin parts being rigidly fixed at their flat ends on the metal strips and the other two being bolt-like Enclose the ends in the hollow shaft so that they are overlapping each other, which is guided either directly or via a roller bearing in the vertical seat of the seat support. .

The invention is explained below with reference to two exemplary embodiments shown schematically in the drawings It shows:

The drive device according to Pig. I contains two endless steel belts which are arranged parallel to one another and run over wheels 5, 6 and 7, 8 which are provided with pins 9 and which have openings 10 corresponding to the pins. A drag link ensures the connection between the steel belts and the slide and consists essentially of two pin parts 11, 12 and a hollow shaft 13. The pin parts are each fixed at their flat end to one of the steel belts 3 and 4 by means of rivets 14 in such a way that w, the two pin-like other ends opposite to each other sunbeds. The length of the two pins is dimensioned so that the pins can be slidably inserted into the hollow shaft I ^ and can carry this hollow shaft; the hollow shaft is axially displaceable; its movement is limited by shoulder parts 15. The hollow shaft 13 carries a two-row roller bearing 16 which is in direct connection with the walls of a vertical slot 17 provided in the support 2.

If the drive wheels 5 and 7 are rotated at a constant speed, the carriage is moved at a constant speed as long as the entrainment member moves in the straight line area of the metal belts? and is located. If the entrainment member comes into the range of one of the pairs of wheels 5, 7 or 6, 8, the speed of movement of the carriage is reduced, reaches the 0 value and changes its sign, this speed reversal following the law of a sine curve thanks to the interaction between the Vartikalechlitz 17 and the rolling bearings 16 takes place.

Steel belts as a drive means for a winding machine have particular advantages and, in fact, what is achieved is that the reversal law can be changed quickly at the end of the running distance can, if the pin gears by other, with other through- ■ eaaern, be replaced. If you wind a spindle large

Durchinessers with a large winding step. "On, so rough Reverse movement take place slowly, ie. the wheels must have one have relatively large durohmeters and vice versa. Thanks to the reversing device according to the invention, there is none Difficulty changing the wheels because the steel belt is very light and easy by means of the pins over the wheels tense. When changing the wheels, however, the steel belts also have to be changed. Thanks to the aforementioned entrainment member, the release of the steel straps from the slide can be done quickly and can even be done without tools.

The steel belt also has the following advantages:

j - greater accuracy and no stretching, *

According to the embodiment of FIG. 3, the drive device contains only a single metal band 18, which is tensioned over two wheels 19 and 20 provided with pins, as well as an entrainment element consisting of one connected to an auxiliary slide 22. Arm 21. The arm 21 is fixed to the metal strip so that it can rotate about a vertical axis 28 "... so that it is not subjected to any torsional stress due to the floating arrangement of the arm the arm 21 is rotatably mounted in the auxiliary slide 22 about its horizontal axis and remains in its vertical position, since it is guided over four freely rotating rollers 23 along two columns 2k and 25 forming the guide of the auxiliary slide.

Also in this case the law of motion is at the ends the running distance is determined by the diameter of the wheels.

The arm 21 is slidably mounted in the auxiliary slide 22, see above that its expansion can be carried out very easily.

As in the aforementioned embodiment, the two columns 24, 25 are not shown in the drawings Supported means carried.

In order to prevent the auxiliary carriage from being carried by the arm 21, a support 26 is provided on which the Auxiliary slide is supported when the arm 21 is on the lower TruÄm of the metal strip 18 is located. To keep the auxiliary slide in its upper position (when the arm is on the upper run of the belt is located), as shown in the drawing, magnetic fastening means are preferably according to the invention provided on the auxiliary slide and on one of the columns, although a spring connected to a stop is also provided can be.
