Abstract
1,262,125. Tyre building drums. N.R.M. CORP. 24 March, 1969 [27 Nov., 1968], No. 15294/69. Addition to 1,181,073. Heading B7C. Bead clamping means for the tyre building drum described in parent Specification comprises an annular set of pivoted arms 15 each carrying a pivoted finger 16 formed with a forked free end and urged away from the drum axis by a spring 18 and a link 14 connected to an actuator 13, operation of which causes the initial gripping of the beads. In use, the bead clamping means are driven towards the transverse plane of symmetry as the sectors are raised by driver 10 operated by screw 5, and as the sectors 8 are stationary by the double acting piston and cylinder device 20.
