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.
