Abstract

843,236. Making finned tubes. GENERAL ELECTRIC CO. April 21, 1958 [May 29, 1957], No. 12548/58. Class 83 (2). [Also in Group XIII] A finned tube for a heat transfer unit (see Group XIII) is formed by folding a strip 11 of aluminium into an L-shape by dies 13, folding the lower limb of the L back on to itself by dies 14, slitting the upper limb of the L by rotating cutters 16 and 17 and then winding the strip on to a tube to which adhesive 20 has been applied so that the cut portions 6 of the strip stand out to form spines.
