Abstract

1302335 Making finned tubes; rolling TRANE CO 19 April 1971 [4 March 1970] 24467/71 Headings B3A and B3M An integral helical fin is formed on the outside of a tube 12 by rolling the tube between die assemblies A and B, the disc-like rolls A 1 to A 8 or B 1 to B 8 of each assembly increasing in pitch and diameter from the leading to the trailing end of the assembly. The change in pitch of the rolls is designed to accommodate elongation of the tube during rolling. The assemblies, of which there may be four, are mounted in a cylindrical body 14 which rotates relative to the tube. The assemblies are skewed so that the tube, which is supported internally by a mandrel 11, is fed axially during rolling.
