A pressure platehas an upper surfaceand a lower surface. A blade die unitfor machining a workpiece by applying a pressure to a principal surface of the workpiece is arranged on the lower surface. A face platehas an upper surfaceand a lower surface, and is arranged such that the upper surfacefaces the lower surfacewith the blade die unitinterposed therebetween. An upper pressure rollerapplies a pressure directed from the upper surfaceside toward the lower surfaceside of the pressure plateto a portion of the upper surface. A lower pressure rollerapplies a pressure directed from the lower surfaceside toward the upper surfaceside of the face plateto a portion of the lower surface. A motor changes a portion that the upper pressure rollerpressurizes, and also, a portion that the lower pressure rollerpressurizes is changed such that the portion that the lower pressure rollerpressurizes is aligned with the portion that the upper pressure rollerpressurizes when viewed from a direction crossing the lower surface

Workpiece machining apparatus

An automatic card-cutting apparatus provided with plural transfer rollers to transfer paper, plural slitter heads to cut the paper in a transferring direction, and a lateral cutter portion to cut the paper in a lateral direction at right angles with the transferring direction to conduct divisional cutting of the paper into plural cards. Each of the plural slitter heads is provided with a side head disposed as to be freely position-adjusted in the lateral direction to cut a side edge portion of the paper into belt shape, and a middle head having an upper blade of disc and a pair of lower blades each of which contacts each of left and right side edge portions of the upper blade, disposed as to be freely position-adjusted in the lateral direction to cut a longitudinal middle waste portion of the paper into belt shape.
