Abstract

808,429. Building tyres. FIRESTONE TIRE & RUBBER CO. Jan. 30, 1956 [Feb. 28, 1955], No. 2880/56. Class 144 (1). In building tyres, tyre bands of elastic material, such as a tread and sidewall band 12 and a tyre carcase 10, are superimposed by spinning the tread about its axis to cause it to expand centrifugally into contact with an external sleeve support 16, Fig. 5, spinning the carcase 10 about its axis on a drum 11, telescoping the sleeve 16 over the drum 11 and then reducing its rate of spin to allow the tread 12 to shrink elastically on to the carcase 10, Fig. 7. As shown the tread band 12 is sleeved or spliced on to an auxiliary drum 17 rotatably supported cantilever fashion on a shaft 19 at one end of a frame 24, 25, and the carcase band 10 is built up on a collapsible drum 11 supported for rotation at the other end of the frame. The sleeve support 16 is mounted for rotation in a pair of ring bearings 27, 28 supported on a carriage 32 which is slidable on guides 58 from a position intermediate the two drums 11, 17, to positions where the sleeve support surrounds either of the drums. This sliding movement of the carriage is effected by a lead screw 52 driven by a reversible motor 55 and engaging a nut 51 on the carriage. Rotation of the sleeve support 16 is effected by a ring gear 36 thereon driven by a motor 33 on the carriage, the motor shaft being extended to carry the inner member 39 of a pneumatic clutch arrangement the outer part 41 of which is mounted on the frame 24 and drivingly connected by a chain 44 and sprockets 45, 46 with the auxiliary drum shaft 19. The arrangement is such that when the sleeve 16 is telescoped over the auxiliary drum 17, the clutch members 39, 41 are engaged by inflating the clutch tube 48 and the drum 17 and sleeve 16 are synchronized to rotate at the same speed. For exact location of the tread band on the auxiliary drum 17 and in the sleeve 16, the drum 17 has radial flange 61 at one end, and the inner surface of the sleeve is contoured to complement the outer surface of the tread band. The tread band is formed initially with an inner diameter slightly less than the external diameter of the carcase to ensure a snug fit, and suitable stitchers may be used to consolidate the tread on the carcase after their assembly.
