ABSTRACT:
A chuck is adapted to be cantilever-mounted for rotation about a longitudinal axis thereof in a winding machine for threads, such as synthetic plastics filament, glass fiber strands and so forth. The chuck comprises a chuck member and an element movable radially thereat between retracted and extended positions under the action of centrifugal force when the chuck is rotated about its longitudinal axis at or above a predeterminate operating speed in use. The element has a head portion which projects radially outwardly from the bobbin tube receiving surface of the chuck member of the chuck when the element is in its extended position, and is located inwardly of such bobbin tube receiving surface when the element is in its retracted position. The head portion either includes a thread-catching device adapted to receive and catch a thread to secure the thread to the chuck member for winding into a package thereon or is adapted to co-operate in use with a part carried by the chuck member in order to form such a thread-catching device.
