The presser roller presses the hollow cylinder toward a counter roller whereby the hollow cylinder is positively held and a working area is formed through which sheet material is fed from which shapes are punched by said tool means when the rollers are rotated. The hollow cylinder roller is also held in position by automatically adjustable guide rollers.</p> |
