ABSTRACT:
Ply stock is delivered to a bias-cutter by a feed mechanism which moves the stock to be bias cut in measured increments of length. The present apparatus provides a smooth continuous surface of a feed pan supporting the full width of the ply stock to a forward edge which is adjustable angularly to the angle of the desired bias cut. The feed pan moves toward the shear line of the bias-cutter with the ply stock held on the surface; then with holding clamps released is drawn away from the shear line while the ply stock is held to the shear line. The feed pan is less subject to distortion or deflection and is relatively insensitive to changes in humidity. Accuracy of both bias angle cut and length of cut are improved.
