摘要： To obtain a push-cutting blade 2, a flexible base 1 and a projection (trapezoid-section projection 21) protruding from this base are formed by etching. Then, a lateral surface or surfaces of the projection 21 is cut into a vertical projection 2b. Lastly, the tip of the vertical projection 2b is sharpened to give a double (or single) cutting edge 2a.

摘要： A method for producing a cutting or embossing roller having a cutting knife or embossing projection that projects out of the surface of a base body of the roller ensures the greatest possible optimal homogeneity of the cutting knife or the embossing projection, while minimizing production duration and costs. Single-layer or multi-layer application of the cutting knife or the embossing projection onto the roller base body occurs by laser resurfacing welding. Each layer is produced using an additional powdered material, which is melted in a melt bath at the weld point. The heat and/or light radiation emitted by the melt bath is detected, at least during application of each layer. Laser power is controlled or regulated as a function of the heat and/or light radiation emitted by the melt bath, so that melt bath temperature remains essentially constant during application of each layer.

摘要： Disclosed is a flex die punching apparatus for forming an aperture in at least one sheet of material. There is a flexible, extrudable platen which, upon exertion of a force against it, extrudes at least a portion of at least one sheet of material through an aperture of a die. The flexible, extrudable platen may have a punch feature, corresponding to the shape and position of the die aperture, which assists in the extruding of the flexible, extrudable platen through the die aperture and also in the formation of the aperture in the sheet of material. In another embodiment of the invention, there may be a second die wherein the at least one sheet of material is placed between the first and second dies to form the aperture in the sheet of material.

摘要： A rotary cutting die includes a translucent or transparent rotary die plate having an inner surface and an outer surface. A cutting rule that defines a cutting design is supported by the die plate. The cutting rule includes a cutting edge, which extends above the outer surface of the die plate, and a support edge disposed within the die plate. The support edge preferably includes a plurality of key-hole shaped notches. Preferably, a plurality of S-shaped hooks are connected to the key-hole notches, and serve to reinforce the rotary die plate and to support the cutting rule in the rotary die plate. The die plate is preferably formed from an epoxy material that, upon hardening or setting, exhibits a low shrink factor.
