Abstract

A winding device for endless threads for automatically exchanging a fully wound bobbin tube against an empty tube, comprising at least two bobbin chucks for taking-up the tubes, and which bobbin chucks are arranged upon a pivotable arm. The bobbin tubes are alternately brought into contact, during pivoting of the pivotal arm, first with the circumference of an accelerating ring and then with the circumference of a friction drive drum. The circumferential speed of the accelerating ring exceeds that of the friction drive drum. The accelerating ring can be driven independent of the friction drive drum.
