Abstract
436,796. Rolling tubes. VEREINIGTE STAHLWERKE AKT.-GES., 67, Breitestrasse, D³sseldorf, Germany. April 16, 1934, No. 11459. Convention date, Nov. 25, 1933. [Class 83 (iv)] Skew-rolling.-A tube A is reduced by first passing it between internal and external rolls tilted so that the passes K1 reduce and feed the tube forward, after which the rolls are rocked so that the passes K<1>6 &c. return the work in the opposite direction and also reduce it. Six sets of roll passes are provided, each set following and reducing the groove made by the previous set. In a modification, the external or the internal rolls may be tiltable to feed back, the opposing roll then being fixed. Fig. 4 shows an arrangement for tilting all the rolls by screws, the internal rolls C being mounted on a curved base to allow tilting. Two rolls C, Fig. 5, may replace each single roll.
