Abstract
673,950. Flexible tubes. ST. HELENS CABLE & RUBBER CO., Ltd., and FAIRFIELD, R. M. Jan. 20, 1950 [Jan. 21, 1949], No. 1704/49. Class 99 (ii). [Also in Group V] A tube of rubber or plasticized polyvinyl chloride is built up on a rubber mandrel and after curing the tube on the mandrel, the mandrel is removed by stretching it longitudinally. A tube may be made by helically lapping neoprene on the mandrel, extruding a layer of rubber over the neoprene, applying textile braid, and then extruding a layer of rubber over the braid. The tube may be reinforced.
