A cutting apparatus for foam sponges with irregular contours comprises a foam sponge clamping mechanism, a cutter driving mechanism, a cutter rotating mechanism, a template, and a main frame. The main frame is equipped with a vertical frame on which are mounted a lead screw, a driving motor, and a clamping mechanism constituted of upper and lower clamping plates that are driven by the lead screw to secure foam sponges. The cutter driving mechanism and the cutter rotating mechanism are respectively installed on an U-shaped table located under the vertical frame; the driving mechanism making use of a motor mounted on the central rear of the table to drive a cutter rocking device through a combination of timing belts and rotary shafts so that the cutter can perform a reciprocating cutting operation, and the cutter rotating mechanism employing a duplicating needle attached to a hand wheel that is located on one side wall of a template insertion groove formed on one side of the table to dominate the rotation of the cutter through chains. Holding a foam sponge slab in the clamping mechanism and moving the duplicating needle of the hand wheel along the periphery of the pattern plate can cut the slab into foam sponges with an outline similar to that of the pattern plates.
