ABSTRACT:
Apparatus suitable for guiding an uncured, deformable semiplastic rubber strip having skived or feathered outer thin edges, such as a tire tread strip or sidewall strip, into precise alignment with a tire carcass mounted on a drum of a tire building machine. Includes a plurality of support rollers linearly mounted for supporting the lower surface of a rubber strip with each support roller being axially movable and resiliently urged in the axial direction by springs mounted in compression at the ends of each support roller; a plurality of upper guide rollers and mounted above the support rollers and linearly offset from the support rollers. Each of the upper guide rollers is preferably canted upwardly and inwardly toward the center of the rubber strip and is mounted for rolling engagement with the top and edge of a thin edge of the rubber strip. Also, a plurality of lower guide rollers are mounted in linearly offset relation with the upper guide rollers and linearly offset with the support rollers. Each of the lower guide rollers is preferably canted downwardly and inwardly toward the center of the rubber strip and is mounted for rolling engagement with the bottom and edge of a thin edge of the rubber strip.
