ABSTRACT:
Apparatus for the loss-free winding of a continuously supplied thread to winding packages at a high winding speed, in which the thread is wound with transverse motion with loss-free transfer of the thread from a nearly wound bobbin to an empty bobbin on a chuck of a bobbin revolver. Loss-free thread transfer is attained by an auxiliary thread guide with a guide edge slanted laterally and outwardly relative to the traverse triangle and terminating in a thread catching eye. The auxiliary thread guide catches the thread in the traverse triangle when moved into the plane thereof, after which the guide is pivoted outwardly and downwardly into a zone where the thread is caught by thread catching means on the empty bobbin or its chuck. The downwardly extending thread loop runs over a mandrel having a bi-conical midportion and a radial arm shiftable laterally along one conical surface in the axial direction of the mandrel. The mandrel functions to initially restrain the thread against movement into the range of the traverse guide to wind a transfer tail on the empty bobbin.
