Abstract
1360512 Tyre inner tubes CONTINENTAL GUMMI-WERKE AG 6 Oct 1971 [8 Oct 1970 (2)] 46528/71 Heading B7C A method of making an inner tube comprises extruding a tubular blank 1 of unvulcanized elastomer coating the inside and outside surfaces, e.g. with talcum, cutting a predetermined length 7, punching a hole 9 for an inflation valve, folding the cut length to enable butt-jointing 19 of the ends 11, 12 and vulcanizing the resulting joined length whilst still in its collapsed condition to form an inner tube. The hole 9 has reinforcement 20 therearound. In the apparatus for performing the method, blade 5 severs the cut length and punch 8 makes the hole 9.
