Abstract

512,232. Making gilled tubes. SCHILD, A. March 4, 1939, No. 7143. [Classes 83 (ii) and 83(iv)] Coiling; soldering.-In making a gilled tube by coiling and soldering a metal band on the tube, the solder seam is made of substantially the same width as the gill leaving the surfaces of the tube and gills otherwise free from solder. The band 1 may be fed over a roller 2 in a flux bath 3, then over a propelled roller 4 in a tinning bath 5 heated by a burner 6 so as to tin its lower edge, then over a scraper 8 and is finally wound on tube 10, the tinning and winding devices and a burner for soldering the gills to the tube being secured to a support traversed along the tube. The roller 4 cooperates with a pressure roller 7.
