Abstract

203,009. St³ting, H. March 29, 1922. Drawings to Specification. Rolling.-Tubes are produced without the use of a mandrel by a process in which the blank is grasped completely over its whole circumference by the rolls of a universal mill having staggered passes, whereby the tube retains a substontially circular section throughout the rolling and the maximum reduction at each pass may be obtained.
