TIRE BUILDING MACHINE STITCHING

摘要

METHOD OF STITCHING A BELT OR TREAD TO A CARCASS IN A TIRE BUILDING MACHINE UTILIZING A PNEUMATIC ROLL Stitching of tire building components, particularly of breaker belt and tread, is improved by use of an airinflated rotatable stitching sleeve having reinforcement cords in the sleeve parallel to its rotation axis. Productivity is improved by application of fluid pressure in the sleeve across the full width of the belt or tread for about one revolution of the carcass before conforming the outward portions of the tread to the carcass.
