Abstract
The blade having a convex or concave edge and a workpiece engaged by the blade are relatively displaced by an oscillating parallelogrammatic linkage so that an arcuate contour is cut in the workpiece. The oscillating radius of the parallelogrammatic linkage and the radii of the curvature of the blade and the cut contour are dimensioned so that the contact between the cutting edge of the blade and the workpiece is a quasi-point contact. This allows rapid cutting for thin pressure-sensitive materials.
