Abstract

183,793. Goodrich Co., B. F., (Assignees of Gammeter, J. R.). July 25, 1921, [Convention date]. Moulding wheel tyres. -Pneumatic tyre casings are moulded and vulcanized by heating the tyre 10 upon a rigid core 11 contained within a mould which is closed at the beads and is open at the .tread during the initial stages and is subsequently closed also at the tread. The mould is formed of shells 15 slotted at 16 to provide vents and the outer portions 20 are slightly inclined so that the tread portions normally separate as shown. The shells are also grooved at 21 to provide a thin flexible portion 22 whereby the tread portions can be pressed together. In use, the tyre is built upon the core 11 which is then enclosed between a pair of shells 15, the inner portions of which engage the neck 11<a> of the core. A number of moulds are superposed in a pan vulcanizer and heat applied causing the rubber to soften and swell and fill the moulds after which the tread portions are forced together and vulcanization is completed.
