METHOD AND APPARATUS FOR CUTTING AND MOLDING STRIP OF ELASTMIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To fit a liner in a manner that air or a bladder release agent is not caught in a molded tire during curing by deforming the liner by means of a heating roller or a die before cutting the liner and forming its edge into the tapered shape. SOLUTION: A movable die and a supporting anvil on an applier are shaped in a manner of forming a compressed section of a liner with tapered front edge and rear edge. The edges are tapered in both directions so that the bonding with smooth tapering can be provided between the edges and other sections of the liner to be wound above the edges. In the shaping of the liner, the pressure applied from a die component 58 to an anvil component 60 by two pistons 52 and a cylinder 54 is preferably approximately 4,535.9kgs (10000 1bs.). It is also important to apply the coating of a proper release material onto a belt 36.
