ABSTRACT:
An automatically controlled machine for cutting a layup of limp sheet material includes a conveyorized vacuum holddown table for advancing a layup of sheet material, compressing the layup and holding it in a fixed position while it is cut by a cutting tool supported by a cutting carriage assembly and moved by the carriage assembly in cutting relation to the layup. An overlay of air-impermeable sheet material wound on a retractable roll carried by the cutting carriage assembly is spread over the layup to cover the kerf formed in the layup by the cutting tool as the carriage assembly advances. The free end of the overlay is secured to a clamping bar at the discharge end of the table. The clamping bar is vertically movable relative to the table between raised and lowered positions.
