Abstract

1,191,937. Moulding tyres. CONTINENTAL GUMMI-WERKE A.G. 5 Oct., 1967 [14 Oct., 1966], No. 45439/67. Addition to 1,096,189. Heading B5A. In a method of moulding and vulcanizing tyre blanks in a press having mould portions 3, 4, the blank is placed around an airbag 10 supported on relatively movable discs 8, 9, the discs being separated during such loading such that the lower disc is adjacent the portion 3 and the bag is of approximate cylindrical form. The discs are then brought to the position shown, with the assistance of a ring 14 urged downwardly by a drive rod 12<SP>1</SP>, with the tyre beads a predetermined distance apart and pressure fluid being applied to the bag. The mould portions and tyre blank are then brought together so that the two portions come into contact substantially simultaneously with the associated side walls of the tyre. Finally, tread forming segments 7 are forced inwardly into contact with the tyre. As described, the portion 3 is stationary and the tyre assembly and portion 4 are driven downwardly at appropriate relative speeds.
