Abstract

An arrangement of articulated grippers for holding a substrate such as a shoe upper to be treated with a reinforcing substance onto a rotatable cube for pressing against a carrier belt of a reinforcing machine. The gripper comprise arms arranged on two sides of a biased plate, each arm being pivotable about a pintle, the arms each having an end which has a wheel in rolling contact with an extension of the biased plate, the other end of each arm having a pivotable flange which is contactable with the outer surface of a substrate loaded onto the biased plate, so as to hold that substrate thereon as the cube rotates during subsequent machine operation.
