Abstract (en)
1. A chuck adapted to be cantilever-mounted for rotation about a longitudinal axis thereof in a winding machine for threads such as synthetic plastics filament, glass fibre etc., the chuck comprising an element movable radially thereon between retracted and extended positions under the action of centrifugal force when the chuck is rotated about its longitudinal axis at or above a predetermined operating speed in use, the element having a head portion which projects radially outwardly from the bobbin tube receiving surface of the chuck when the element is in its extended position, and is located inwardly of that surface when the element is in its retracted position, the head portion either including thread catching means adapted to receive and catch a thread to secure the thread to the chuck for winding into a package thereon or being adapted to co-operate in use with a part carried by the chuck in order to form such a thread catching means.
