Abstract (en)
A punching apparatus punches a sheet of paper into products and a scrap by a flat pattern being implanted with blades of a shape of a product. No prior punching apparatus cannot separate products from a scrap at the time when products have been punched. This invention uses a flat pattern(K) upside down. The flat pattern have closed-loop blades on the bottom surface. The blades shape products. A lower roller (2b) presses a sheet of paper to the blade-implanted bottom surface of the flat pattern. Products are punched out from the sheet by the blades one by one, while the flat pattern progresses and the lower roller rotates. The products are withdrawn from one side of the punching section. The scraps are taken out from the front part of the punching section. <IMAGE>
