Abstract

1,193,595. Moulding tyres. UNIROYAL ENGLEBERT DEUTSCHLAND A.G. 31 Jan., 1969 [8 Feb., 1968], No. 5376/69. Heading B5A. In a method of curing a pneumatic tyre in a bladder-equipped tyre moulding press, the bladder is filled with a liquid heating medium, during the main heating period, at a high pressure to force the tyre against the mould of the press, and at a temperature approximately that of the maximum vulcanizing temperature of the tyre; in the last phase of the main heating period the bladder is emptied by introducing thereinto a gaseous or vaporous medium under a high pressure and at a temperature at least equal to the said vulcanizing temperature while opening a bladder discharge pipe, without interrupting the curing operation. The liquid medium may be water and the other medium air, inert gas or steam.
