Roller centering apparatus.

摘要

A means and method are disclosed for applying a stabilizer ply (12) to a tire building drum (17) and more particularly a means and method for cutting and applying the stabilizer ply material, including means for cutting (46) the stabilizer ply material between cords disposed therein and correcting (42) for variations of the cord angles during the application process in order to provide an improved splice between the leading and trailing edges of the stabilizer ply material. The ply material is positioned centrally with the ply applicator (16) by centering apparatus (141) comprising steerable rotatable members (142) having peripheral projections (144) to engage the surface of the ply material, and edge sensing means (165) to control the steering of the rotatable members.
