Abstract
625,987. Making tubes. QUARNSTROM, B. L. March 31, 1947, No. 8621. Convention date, April 15, 1946. [Classes 83 (ii) and 83 (iv)] [Also in Group XXVIII] Angular bending; soldering; welding; shearing.-A strip is skelped to form two parallel tubes connected by a web to facilitate welding the joint. The strip 34 is fed from a reel 30 through skelping rolls 38, 48, 56, 62, 68, 74, 82, 88, to form double tubes 20 connected by a web 22, Fig. 14. Solder 94 is fed by rolls 98 and flux from a container 100 are fed to the web 22 and the joints 24 are soldered by the heat from welding electrodes 102, 104 in a transformer circuit whilst the tubes are positioned by rolls 112. The solder alloys with the tube to seal the joint, which is simultaneously welded. Rolls 120 spring open the gap in the joint and tubes 124 supply a reducing &c. gas. The tubes may be separated by slot cutters 162, 160, which shear the connecting web 22. The tubes are heated by rolls 132, 134 in a transformer circuit 136 and cooled by passage through a chamber 137. The exterior of the tubes may be tinned by passage through a bath 142 and cooled by a cooler 152 and finally cut to length by a shear 158. Various joints, Figs. 14-18, not shown, may be used.
