Abstract
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.
