Abstract
1333815 Rolling tubes VALLOUREC (Usines a Tubes de Lorraine-escaut et Vallourec Reunies) 15 Sept 1971 [17 Sept 1970] 42932/71 Heading B3M A rolling mill (such as a pilger mill whose housing 2 is reciprocated relative to a workpiece tube 5) is provided with tube grips 8 and 9 for supporting the tube during rolling, the grips being laterally displaceable out of the rolling line to facilitate roll changing. Each tube grip is carried on a slide 6 which is guided in the mill frame and is movable by a double-acting hydraulic jack 13 (Fig. 3). The slide is normally locked in position by wedges 14 and 15 and a biasing spring 17, but can be released by operating a jack 16 acting in opposition to the spring. The tube grips are rotatable about the axis of tube 5 by a transmission which may include splined shafts for allowing lateral shifting of the grips.
