A machine for cutting cardboard and other articles comprising a frame;
- a platen affixed to the frame substantially vertically thereon, a movable platen pivotally mounted on the frame, a horizontal shaft carried by the frame to impart an oscillating movement to the movable platen and rods pivoted on the shaft and to the movable platen, a chassis, parallel arms pivoted on the chassis and a transverse shaft mounted in the frame, a chain and chain wheels mounted on the shaft, a crank on the horizontal shaft to which one end of the chassis is affixed and a cylinder mounted on the frame to which the opposite end of the chain is affixed, a cam track mounted on the frame and rollers carried by the chassis to engage the cam track and a motor for driving the horizontal shaft, rotation of the shaft lifting the movable platen from a sheet receiving position to a delivery position, a pusher rod for feeding the sheets onto the movable platen, a centering member and blades thereon which cut the sheet on the movable platen, suction members for securing one portion of the sheet on the movable platen whilst the other portion falls away by gravity, means for releasing the suction members when the movable platen is in its horizontal position and a conveyor for removal of the portions released from the movable platen.
