Disclosed is a drive apparatus for a device for applying paraffin wax to yarn. In the device, a solid block of paraffin is mounted on a polyhedral bolt which is driven by a whorl or drive pulley. The whorl, in turn, is driven by a continuous drive belt. Advantageously, a plurality of similar devices are mounted on the same open-end spinning machine so adjacent devices may be driven from the same drive belt. Bracing elements hold the yarn against the rotating face of the paraffin block of each device to ensure uniform application of paraffin.

Drive apparatus for a paraffining device

A mobile supply station (7) is connected by flexible supply lines (10, 11) to a stationary connection point (1). The flexible supply lines (10, 11) are supported by a guide chain (2), the surplus length of which is taken up and laid down in a loop (21) during the movement of the supply station (7). The curvature of the loop (21) is dictated by a return wheel which rolls freely upon that part of the guide chain (2) connected to the stationary connection point (1).
