Abstract

651,829. Rolling finned tubes. CALUMET & HECLA CONSOLIDATED COPPER CO. Sept. 27, 1946, Nos. 18404/49. Convention date, Oct. 1, 1945. Divided out of 651,774. Drawings to Specification. [Classes 83 (ii) and 83 (iv)] Skew-rolling.-The subject-matter is similar to that of Specification 651,774, but the claims are directed to a finned tube produced by applying rolling pressure to a tube in a radial inward direction to displace material for the fins radially outwards without axial pressure. Specification 651,775 also is referred to.
