摘要： A plastic resin cutting apparatus for cutting a plastic extruded from an extrusion opening provided in a flat surface of an extrusion block. The apparatus comprises a rotating shaft disposed substantially perpendicular to the surface of the extrusion block with its front end positioned opposite to said surface; a drive mechanism for rotating the rotating shaft; and a cutting tool interposed between the surface of the extrusion block and the front end of the rotating shaft and having formed at its front surface facing the surface of the extrusion block at least one cutting blade having a flat cutting edge. At least the front end portion of the rotating shaft is urged resiliently toward the surface of said extrusion block by the action of an elastic member such as a spring. The connection of the cutting tool to the shaft is a universal connection. Thus, the cutting tool can tilt in any desired direction with respect to the axis of rotation of the rotating shaft and thereby maintain the cutting edge of the blade flat against the flat surface of the extrusion block. The rotating shaft has mounted thereon at least one drive pin which projects forward and comes into engagement with the cutting tool. The rotation of the rotating shaft is transmitted to the cutting tool through the drive pin.
