摘要

The die has upper and lower base plates (6.1, 6.2) that can move relative to each other. Flat-cutters (3.1, 3.2, 3.3) made from chromium-nickel stainless steel are fixed to the plates. The flat-cutters are provided along an intersecting-line of the plates. The cutters are aligned with their full planar sides facing the base plates. The plate (6.1) has arresting-units (9) for prefixing the flat-cutters.
