Abstract
604,066. Rolling ribbed tubes. CALUMET & HECLA CONSOLIDATED COPPER CO. Nov. 22, 1945, No. 31548. Convention date, Sept. 14, 1942. [Classes 83 (ii) and 83 (iv)] Skew-rolling.-In means for making integral finned tubing in which the fins are raised by rolls arranged about the periphery of the work one or more of the rolls are radially withdrawn to reduce or discontinue the. finning operation on a portion of the tube. Each roll end is journalled in a pivoted bearing 22 slidable in radial guides 20 in end plates 17. Adjustment of the end plates skews the rolls according to the pitch of the fins. The bearings are connected by adjustable screws 36 to the rams 35 of fluid-pressure cylinders 33 and operated by a valve 38 to withdraw the rolls from the tube. One roll only may be retracted.
