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, 59
