In a winding apparatus for endless threads, a revolving disc (6) has at least two clamping chucks (8, 10) rotatably supported on the periphery thereof. A friction roll (2), the shaft (4) of which as well as the shaft (12) of the revolving disc (6) are mounted in a frame (14) at fixed locations. The shaft (12) is connected to a first drive device (120) and the first shaft (4) is connected to a second drive device (40). Each clamping chuck (8, 10) is provided with its own third drive device (80), and fourth drive device (100) respectively.

Winding apparatus for endless threads

In a winding apparatus for endless threads with a revolving disc (6) in the periphery of which at least two clamping chucks (8, 10) are rotatably supported and with a friction roll (2) the shaft of which as well as the shaft (12) of the revolving disc (6) are mounted at fixed locations in a frame, a shaft each (4, 12) is connected to a first drive device (120), and with a second drive device (40) respectively. Each clamping chuck is provided with its own third drive device (80), and a fourth drive device (100) respectively. The contacting pressure between the friction roll (2) and a respective clamping chuck each can be adjusted as a function of the diameter of a thread package being built on a clamping chuck.

A bobbin chuck for winding manmade threads can have a length of e.g. 1200 mm and can consist of a bearing portion and of a cantilevered portion supported by it. The cantilevered portion includes an extension (66) of a shaft (64) supported directly by the bearings and a tubular part (60) taking up the bobbin tubes which is connected at two locations (68, 70) to the shaft extension (66) and secured against rotation relative thereto. The shaft extension (66) as well as the tube (60) are free to perform oscillations according to their natural oscillation modes.
