IPC: D01H9/18
Filed: 1992-08-18
Abstract: An automatic winding machine has a transport system in which cop plates circulate. The plates have a perpendicular central stem on which a cop or tube is held. To hold the cop firmly, an expansion medium is employed, in the centre of the stem, and this is engaged under spring tension. The expansion grips are engaged or released by a mechanism standing alongside the cop plate. Pref. the plate is circular to fit into the transport system and move easily. A central rod is bolted vertically to the base plate to support a mechanism, forming the stem on which the tube (22) is held. The windings on the tube (22) form a cop (23), which is held rigidly in position by the catches (10,12). These are in pairs, equidistant around the stem, at three positions. The catches protrude through slots in the tubular case (4") and swivel on fixed pieces (14,15) held on the central rod. Moving pieces, which have top cones, are pressed up from the base by a spring loaded ring (17) and this causes the catches (10,12) to press outwards, gripping the interior wall of the tube (22). ADVANTAGE - The cops are quickly and easily released or engaged, when the mechanism has been operated, and this ensures the cops are held securely in transit.
