Abstract

157,168. St³ting, H. Jan. 8, 1921. Rolling tubes. - A tube r is rolled in a universal mill by means of stretching rolls w<1> - - w4 whose surfaces form a pass of less diameter than the roll surface so that separation of the tube from the mandrel d may take place without the formation of sharp ribs at the points of separation b. The Specification as open to inspection under Sect. 91 (3) (a) comprises also modifications in which the rolls have cylindrical or convex peripheral surfaces. This subject-matter does not appear in the Specification as accepted.
