VERFAHREN UND VORRICHTUNG ZUM SCHNEIDEN EINES ELASTOMEREN KORDVERSTÄRKTEN LAMINATS

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 DEG relative to a normal plane (NP) perpendicular to the ply and parallel to the cords, preferably being cut at angles of about 80 DEG . This can be done precisely and quickly. The cutting means (102) provides improvements to these splice surfaces.
