Abstract
402,318. Skew-rolling tubes. KOCKS, F., 5, Wilhelm-Heinrich-Weg. D³sseldorf, Germany. April 6, 1933, No. 10359. Convention date, Feb. 10. [Class 83 (iv).] A tube has its wall thickness reduced by longitudinal elongation by rolling on a skew mill of more than two rolls a of diameter about 1¢ times the tube diameter and not more than 150 m.m. diameter revolving at 200- 400 revolutions per minute. The mandrel is supplied with lubricant by a piston h through a bore e and ducts f. The direction of the peripheral speed of the rolls is inclined at less than 80‹ to the axis of the tube.
