Abstract

691,195. Tyre-building apparatus. DUNLOP RUBBER CO., Ltd. May 22, 1951 [May 26, 1950], No. 13253/50. Class 144(i). In a tyre-building apparatus comprising a flat-band forming drum 1, ply turndown is effected by a number of circumferentially spaced, outwardly inclined arms 16 of a device 9 located coaxially with the drum 1, the tips 16a of the arms lying on a common pitch circle and the arms 16 being engaged and forced radially inwardly for ply-turndown by a coaxial bead-setting device 10 on axial movement of the latter to apply a bead. Figs. 1 and 2 show a ply-turndown device 9 and beadsetting device 10, for one end of the drum 1, arranged on the driving shaft 2. The turndown device 9 comprises an annulus 14 fixed by brackets 13 and a ring 12 to a sleeve 11 slidably mounted on the shaft 2. The arms 16 are hinged to the annulus 14 and spring-urged to the outwardly inclined position shown. The bead - setting device 10 comprises a bead-carrying ring 30 bolted to the free ends of circumferentially spaced angle brackets 27 radially adjustably bolted to a ring 26 secured to a sleeve 24 which is slidably mounted on the sleeve 11. Handling rings 13a and 33 are respectively secured to the plyturndown and bead-setting devices. In operation, with the drum 1 stationary and a bead mounted on the carrying-ring 30, the turndown device 9 is moved towards the drum until stopped by an adjustable stop 22 secured to the shaft 2. In this position the arms 16 overhang the edges of the plies 19. The beadsetting device is then moved towards the drum and the bevelled inner periphery 32b of the carrying ring 30 engages the arms 16 and forces them radially inwardly against the action of the spring-loaded hinge 17, thereby causing the arm tips 16a to turndown the plies ready for application of the bead. In the final movement of the setting device 10, the carrying-ring 30 passes completely over the arms 16 and presses the bead on to the plies against the drum edge. The ply-turndown and bead-setting devices for the other end of the drum are similar to those described above but are mounted on an axial tubular supporting member which has a spindle arranged to be detachably supported in an axial bore in the end of the drum driving shaft. In this construction the ply-turndown device is fixed to the supporting member and the beadsetting device is slidable on said member.
