Abstract
595,024. Making tubes. SOC. ANON. DES USINES CHAUSSON. May 15, 1945, 12197. Convention date, Jan. 5, 1943. [Classes 83 (ii) and 83 (iv)] Flat ribbed tubes are made by supporting a flat tube on a mandrel and raising integral fins by pressing or rolling. In Fig. 1 a tube 1 on a mandrel 2 is passed between ribbed rolls 5, 6. The ribs may be transverse or otherwise and the mandrel may be ribbed to form internal fins during the external finning. In Fig. 5, a tube 24 on a mandrel 25 is intermittently fed through a press with tools 22, 23 of increasing depth and integral fins are formed progressively. Alternate tools may be connected in sets and be provided with rounded and sharp edges to assist the finning.
