1333662 Moulding tyres VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT REZINOTEKHNICHESKOGO MASHINOSTROENIA 1 April 1971 8777/71 Heading B5A In a tyre moulding apparatus having means for opening and closing two-part moulds and for transporting the cured tyres laterally from their moulding positions to discharge positions and for loading green tyres into the open moulds, such means includes a frame 1 with wheels 2 on rails 3 which moves relative to fixed two-part moulds 6 on a support 7. The frame carries a device 4 movable laterally and vertically of the frame to enable hydraulically driven part-rotary members 5 to engage the upper halves of the moulds to either lock or unlock them to their lower halves and to transport the upper halves, with the cured tyres, laterally to discharge positions. The mechanism for moving the device 4 relative the frame includes two crank wheels 14 at the frame sides driven via clutches and reduction gearing from a motor 25, to each of which is connected a link 15 with a roller 12 engaging an L-shaped guide in the frame side. The rollers 12 are attached to the device 4 whereby rotary oscillation of the cranks produces vertical and horizontal movement of the device 4 within the frame. Each link 15 has a guide roller 18 engaged by a guide 19 at the frame side to ensure appropriate movement of the device when the roller 12 passes from the horizontal to the vertical section of the L-shaped guide and vice versa. Each mould includes a bladder 31, Fig. 5, and a bayonet connection between their two parts 8, 9 operated by the member 5. The cured tyre is carried in an upper part 8 by the member 5 to a mechanism 34 including grips 35 which withdraw the tyre and transfer it to a roll conveyer 36. During this stage green tyres are transferred from a pivoted receiving mechanism 27, carried by the frame, to the lower mould halves.
