Abstract

1,119,079. Moulding belts. BRIDGESTONE TIRE, K.K. 20 Dec., 1965 [28 Dec., 1964], No. 63927/65. Heading B5A. A rubber conveyer belt 9 is intermittently forwarded between top and bottom endless belts 3, 4, and side belts (5, 6), (Fig. 3, not shown), extending therebetween which run over side plates (7, 8), and is clamped at 14 and stretched by a device 15 prior to vulcanizing between vertically displaceable heated platens 1 and 2; the belts 3, 4 may be preheated by heaters 23, 24. The belts 3, 4 and side belts (5, 6) and the plates 7, 8 are vertically adjusted independently of the heating platens 1, 2. The belts 5, 6 may be dispensed with if the side plates 7, 8 are horizontally displaceable. In an alternative embodiment (Fig. 6, not shown) the upper return portions of the endless belts (3, 4) pass around guide rollers (R) at either end of the press daylight and are thereby returned between the heated platens (1, 2). The process, by totally enclosing the conveyer belt, facilitates vulcanization of belts not provided with cloth or cord reinforcements. The endless belts (3, 4) may be provided with embossed patterns or pictures for transfer to the moulded article and the moulding surfaces thereof are cleaned by brushes (17, 18). The upper heated platen (11), (Fig. 7, not shown) may be stationary with the lower platen, (2<SP>1</SP>) suspended on a plurality of bladders (19) and displaced by varying the internal pressure thereof. Alternatively the lower heated platen (2<SP>1</SP>), (Figs. 8a and 8b, not shown), is provided with a sawtoothed portion (20) on the under surface thereof which engages with a similar toothed portion (22) whereby the platen (2<SP>1</SP>) is vertically displaced in response to horizontal movement of portion (22). The endless belts 3, 4, 5, 6 are normally driven in the same direction as that of the rubber belt, but may independently be movable in the opposite direction.
