ABSTRACT:
The present invention describes an improved pressing roller for a tire building machine. The roller comprises a cylindrical sleeve with each end attached to a housing. Inside the sleeve, and between the housings is a spring biased to separate the housings. A multiplicity of ring shaped inner bearings circumferentially surrounding the sleeve in a parallel arrangement and a multiplicity of ring shaped outer bearings circumferentially surrounding the inner bearings in parallel arrangement. The outer bearings are rotatable relative to the inner bearings. As the roller is moved into operating proximity of the tire the spring is displaced away from the rotating axis of the roller causing the outer bearings to press on the tire and provide the pressure necessary for a stitching operation.
