Abstract

1339388 Cutting-out dies BOHLER & CO AG Gebr 23 Oct 1972 [22 Oct 1971] 48730/72 Heading B4B A cutting-out knife, e.g. for cutting textile fabrics, plastics, leather, rubber, comprises a serrated cutting edge having teeth with a tip spacing t of 0À5-5 millimeters, the depth h of each tooth at most being 5 millimeters and the knives being hardened so that the hardness of each tooth increases from its tip to its root and the hardness decreases or remains constant from the root of each tooth to the body of the knife. In a modification, the teeth may be formed with festoon-shaped portions C, Fig. 2, with the cross-section shape A-B being of diamond shape, Fig. 3 (not shown). Various degrees of hardness for the teeth are disclosed.
