Vorrichtung zum Herstellen eines verstärkten Gewebes aus einem ungehärteten Elastomerband

摘要

Bias cutting apparatus 10 is disclosed, including a shuttle head 18 which can be translated along a longitudinal axis between an assembly table 14 and a lead-in table 12, in which the shuttle head has a vacuum pick-up for picking up a ribbon S of uncured elastomeric material. The shuttle head includes a pick-up plate 34 having a plurality of apertures 42 communicating with the source of vacuum. A cutting knife 20 is provided on the edge of the assembly table for cutting the strip of ribbon, and the assembly table and cutting knife can be adjusted angularly with respect to the lead-in table. The pick-up plate has an inverted V-shaped edge 40 at the leading end of the shuttle head immediately adjacent the cutting knife, so as to allow a variety of angular displacements of the assembly table relative to the lead-in table without having to change the pick-up plate.
