Abstract
161,009. Burke, W. B. Jan. 27, 1920. Jackets and covers.- In re-treading tyres &c. by the method described in Specification 112,312, in which a heating element is interposed between the tyre body and tread, the heating element comprises two layers of vulcanized rubber between which is placed a wire capable of being heated by an electric current. Upon a strip of rubber 7, Fig. 2, is placed a wire 9, bent into a series of parallel reverse loops extending preferably obliquely across the strips. At equal distance the wire 9 is cut and the two ends thus formed are bent outwards and connected at 10 to leads 11, 12. A second layer of rubber 8 is then pressed on the first, embedding the loops. The cover 1, Fig. 1, with inner tube 5 is mounted on a rim 4, the element 3 is placed on the cover, the tread 2 is bound on with tapes 6, the tube 5 is inflated and a current is passed through the wire. After vulcanization, the ends 10 are cut off. In a modification, the wire is pressed into contact with a single layer of rubber.
