Abstract
843,433. Moulds for tyres. DUNLOP RUBBER CO. Ltd. Feb. 28, 1957 [June 15, 1956], No.18508/56. Class 87(2). A tyre mould, especially for retreads, has a heatable tread ring comprising at least one part for moulding a pattern on the tread and shoulder portions of the tyre ; each part extending the whole of the axial width of the tread ring at any transverse cross-section, and being associated in the mould with heated adjustable plates for contacting the flat mid-wall regions of the tyre and with means for supporting the tyre beads a tread ring 1 comprises a metal band 2, heated by coils 3, and segments 4 having flanges 4a, 4b for moulding the shoulders 13 of tyre 14. Top and bottom plates 5 and 6, heated by coils 7, 8, contact the tyre side walls and are located in a screw press Fig. 2 (not shown). The tyre beads are supported during inflation and curing on a rim 15, and in other modifications the beads are supported by annuli which are forced against the plates or may alternatively be formed integrally with them. Specification 626,316 is referred to.
