Abstract
663,932. Making machine knives. SVENSKA SKOFABRIKANTFORENINGEN. March 24, 1949 [April 1, 1948; Oct. 13, 1948], Nos. 8059/49 and 8060/49. Class 83 (ii). [Also in Group VIII] In a method of making dies for cutting blanks from leather and the like, hardened steel strips 1, Fig. 2, have cutting-edges 2 ground thereon and are bent cold to the desired closed configuration. Dies for cutting glove blanks and the like in which the cutting-edges of two die portions 8, Fig. 3, are required to coincide, are made from several lengths of strip 4 . . . 7 having a cutting-edge 2, Fig. 5, in the same plane as one side of the strip. The strips may be joined by welding, riveting, &c. Dies may be made from strips with double cutting-edges, the dies being used in turn on their opposite edges for cutting right and left hand blanks.
