Abstract
465,107. Cutting - dies. UNITED SHOE MACHINERY CORPORATION. Sept. 26, 1935, No. 26600. Convention date, Oct. 31, 1934. [Class 3] (i)] [Also in Group XXII] A cutting-die, particularly for shoe part blanks, comprises, in one form, a metal core plate 10 to the periphery of which a cutting blade 12, preferably double-edged, is secured by welding flanges 14 thereto. Prick markers 20 and stripping members in the form of rubber plugs 28 are secured in holes in the core plate, and a finger hole 34 is also provided. Size markings 18 are provided in the blade. In another form, the die is provided with a flat cutting blade welded to a strip 40 having lugs 42 in place of the flanges 14. A method of making a set of dies of various sizes consists in cutting with shears from a metal plate a template of the shape of a paper pattern, and using this template in a pattern grading machine such as that described in U.S.A. Specification 1,079,022 to make a set of core plates ; holes are then drilled in each core plate, a blade is bent round the core plate by a roller or by clamping plates and the blade flanges are united to the core plates by welding, the ends of the blade are joined by filing them away to receive a V -section piece of material which is welded in, and the markings 18 are then formed in the blade by pressing. The second form of the invention involves welding the flat blade and the strip 40 together either before or after the attachment of the latter to the core plate.
