Title: Guide mechanism for tire building machines
IPC: B29D30/30
Filed: 1963-04-03
Abstract: 1,006,367. Ply feeding mechanism. FIRESTONE TIRE & RUBBER CO. April 3, 1963 [April 26, 1962], No. 13163/62. Heading B7C. [Also in Division B6] A guide mechanism (Fig. 1) for a tyre building machine comprises a plate 20, adapted to be positioned adjacent to a tyre building drum (Fig. 2, not shown), carrying a pair of guide members 40, connected for simultaneous relative movement transverse to the plate, and selectively positional stop means 60, engageable by a latch means carried by one guide member, serving to retain the guide members at one of a number of predetermined positions. In use, fillers, chafers, sidewall strips &c. are fed over rollers 23 and rollers 85, carried by the guide members and angled to direct the strips against the outer edges of the guide members, and then on to the drum (not shown). Fig. 3 shows the underside of the plate 20 and the mechanism for positioning the guide members. Two endless chains 75, connected by gears and a further chain at one end, are attached to holders 41, which carry rods 44 extending up through guide slots 26, 27 and supporting the guide members 40. Holders 41 are carried by guide rods 29, 30 beneath the slots, and a spring 80 biases the mechanism so that the guide members 40 tend to move apart. One holder 41 (Figs. 3, 6) carried a latch means 52 (details Figs. 5, 7, not shown) which, by engaging with one of a series of stops 60 on a rod 33 (Fig. 3) locks the guide members in one position. In use, the latch holder 52 is depressed (Fig. 6) from its usual horizontal position (Fig. 4, not shown) for a moment, by a release plunger 62, extending through a slot 28 in the plate 20. This enables the guide members to be moved relatively until the latch again engages a stop 60. As shown in Fig. 6, each stop has a notch 71, and the rod 33 carrying the stops has a knob 35 (Fig. 3) by which the rod is turned so that certain stops, having their notches in line with the latch means, do not affect the movement of the guide members, which move until the latch next catches on an appropriately orientated stop. Thus the operator selects the " stopping places" for guide members 40 from those determined by the positions of stops 60 on rod 33.
