Abstract: Apparatus for frictional surface driving of a textile bobbin during cross-winding utilizes three or more annular drive bodies rotatably supported axially adjacent one another on a central drive shaft with a transmission mechanism intermediate adjacent pairs of the drive bodies for coupling them in driven relation to the drive shaft and in speed-change relation to one another. The driving apparatus is thereby particularly adapted for peripheral driving of a conical bobbin during winding, at least two of the annular drive bodies preferably being utilized for peripheral driving engagement with the bobbin. The speed-change ratios are predetermined as a function of the rotational speed of the drive shaft and the conicity of the bobbin.

Abstract: A yarn traversing mechanism having oppositely traversing yarn engaging elements and transfer means that disengage yarn from one element and transfer it into engagement by an oppositely traversing element at a plurality of different yarn reversing locations at each end of the yarn traverse. The different reversing locations are determined by an unequal spacing of yarn engaging elements and by either selectively raising a yarn guide member or displacing yarn engaging elements differently at different traversals of the yarn.
