Abstract

1,232,697. Radial tyre building drum. UNIROYAL ENGLEBERT FRANCE S.A. 23 Aug., 1968 [15 Sept., 1967], No. 40326/68. Heading B7C. A radial tyre building drum for shaping a first stage carcass comprises a pair of coaxial ring assemblies 10, 10a symmetrically axially movable about line M-M, each assembly including a circumferential arrangement of arms 40 each of which has on its outer end an arcuate segment 45, the segments 45 defining in the radially contracted position of the arms, Fig.1, an annular surface over which is stretched an annular rubber strip 30, wherein in the contracted position of the arms a first-stage carcass T may be slid over the ring assemblies, but in the extended position of the arms the strip 30 contacts the tyre bead in an air-tight manner, Fig. 3. The ring assemblies 10, 10a are supported on sleeves 11, 12, respectively, with sleeve 12 slidable on an extension 11c of sleeve 11. Means 80, 80a axially move the assemblies. In use of the drum a carcass T is slid over the ring assemblies and the sleeves 11, 12 moved apart causing chains 59, 591 to pull on links 52 52a. These links are connected by further linkwork to links 56, 56a which mount rollers 55, 55a, which latter links are caused to rotate anti-clockwise whereby the rollers force rings 6, 6d to move towards each other. Rings 6, 6a being connected by rods 7, 71, 7a, 71a cause inward movement of rings 4, 4a, whereby arms 40, 40a are pivoted about pins 44, 44a, hence causing strips 30, 30a to contact carcass beads 2, 3. The chamber C within the tyre is airtight and compressed air is pumped in through line 15 to inflate the tyre at the same time as rings 11, 12 are moved axially towards one another to the arrangement shown in Fig. 3. Transfer ring R causes breaker-tread assembly to adhere to the carcass and rings 16, 17 shape the tyre. To remove the now-formed secondstage carcass the rings 11, 12 are moved even further together whereby by the movement of linkwork, rollers 55, 55a are moved inwards and arms 40, 40a attain their Fig. 1 position, allowing the carcass to be removed. The chains 59, 591 are spring tensioned.
