Abstract

A tire building machine having opposed support shafts for engagement with opposed ends of a tire building drum and opposed ply turn down and bead setting mechanisms movable axially along the support shafts toward and away from the drum. The machine includes parallel bearing rails extending substantially the length of the machine. The ply turn down and bead setting mechanisms are carried by opposed housings which are supported by bearings which ride on the bearing rails. The ply turn down and bead setting mechanisms also carry bearings which ride along the shafts during axial advancement thereof. Finally, the turn down mechanism is supported on the housing at multiple points about its periphery to insure correct alignment thereof.
