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.

Abstract: A winding machine comprising a traversing mechanism, a yarn-contact roller acting as a measuring and/or drive roller and adapted to be brought into contact with the winding tube or bobbin, and a bobbin revolver which is adapted to be rotated and locked in position and on which are mounted for rotation at least two tube chucks which are alternately brought into friction contact with the contact roller in a bobbin-changing position.
