ABSTRACT:
The yarn crossing device of a sectional warping machine has a height adjustable cross reed (16), two guide rods (28, 29) which are able to slide in opposition to each other, as well as a horizontally displaceable leasing device (34, 35). Drive motors (22, 33), which are independent from one another and separately controllable, are allocated at least to the cross reed (16) and to the guide rods (28, 29). Preferably a separate drive motor (38) for the leasing device and a cross-wound motor (17) for the oscillating motion of the cross reed (16) is also provided. The independent drive motors make possible automation and programming of the different operational sequences which are necessary for the formation of yarn crossings or the rectification of breakages.
