METHOD AND APPARATUS FOR CUTTING A CORD REINFORCED ELASTOMERIC LAMINATE

摘要

This invention pertains to a unique method and apparatus 100 for cutting an intermediate article of manufacture, the intermediate article of manufacture being a cord reinforced elastomeric laminate 10A. More specifically, the invention relates to methods and apparatus for cutting a cord reinforced elastomeric laminate, the laminate 10A, when cut to length, becoming a carcass 10 for a pneumatic tire. The apparatus 100 of the present invention can cut a cord reinforced ply 20 at angles creating large substantially flat planar splice surfaces without significant deformation or precuring of the unvulcanized elastomeric material. The cut surfaces can be cut at angles greater than 60.degree. relative to a normal plane (NP) perpendicular to the ply and parallel to the cords, preferably being cut at angles of about 80.degree.. This can be done precisely and quickly. The cutting means 102 provides improvements to these splice surfaces.
