The gripper assembly, shown in in the figures, is a mechanical mechanism which is attached to the "Z" axis on a robot. It is used to transfer a collated package from the collator table to the layup table. The operation of this assembly is described below. The assembly is shown in Fig. 1 above the collated package of prepreg and core. Cylinders "B" and "C" are mounted on a plate, which is attached to a slide, which moves forward (extended) or backward (retracted) by cylinder "A." Cylinder "A," as shown, is extended. A phantom line is constructed from the package upward to illustrate that the grippers will clear the package edges. Cylinder "B" and "C" are also extended. In operation, the "Z" axis on the robot is extended which lowers the gripper assembly down to the collated package.
