RUBBER STRIP MATERIAL MOLDING APPARATUS AND METHOD OF MOLDING RUBBER STRIP MATERIAL

摘要

A rubber strip material of given cross-sectional shape is stably molded without drop of an extrusion speed from molding die. As means therefor, there is provided rubber strip material molding apparatus (10) for use in a tire manufacturing process in which unvulcanized rubber strip material (S) extruded from molding die (20) is spirally wound to thereby form a rubber member for tire, which apparatus comprises a rotatable pair of rolls (24,26) fitted to a distal end portion of the molding die (20) with their circumferential surfaces opposite to each other and comprises a delivery port (28) disposed in a facing interspace of the pair of rolls (24,26).
