Die Members Patents (Class 101/28)
  • Publication number: 20020043161
    Abstract: This invention relates to a relatively thin cladded graphic arts impression graphic arts impression die plate (20) having a steel layer (22) which is integral throughout the extent thereof with a layer of copper (24) or bronze. A relieved design-defining surface may be formed in the copper or bronze layer by a chemical etching process or by chemical milling. In the case of chemical etching of the graphic arts impression die plate (20), a design-defining layer of photo-resist is applied to the outer surface of the copper layer (24) or the bronze layer and the relieved design is formed in the copper or bronze layer using a conventional ferric chloride etching solution. The etched graphic arts impression die plate may be mounted on an etchant-resistant backing or magnetic support member (28) to present an assembly which increases the thickness of the die assembly sufficiently to permit use thereof on standard stamping and embossing equipment without modification of the die-supporting chase.

  • Patent number: 6349639
    Abstract: A flexible counter for an embossing system provides resilient support under a sheet which opposes pressure from a contoured die forming an embossment in the sheet. The flexible counter includes a resilient mat and a fixed bolster which supports the mat. The bolster has peripheral walls which extend around sides of the mat so that an upper portion of the mat protrudes above the peripheral walls. In addition, the bolster includes a resilient bumper that bounds an upper portion of the mat. An upper edge of the bumper is about flush with an upper surface of the mat. The walls have a peripheral channel in which the bumper is disposed. The bumper is formed of a resilient material having higher rigidity than the mat, thereby controlling the flow and stretching behavior of the upper surface of the mat as compressed during an embossing operation.

    Abstract: A security element for the authentication of a substrate has a pattern comprising optical diffraction elements which are embossed in a carrier material of plastic material and unembossed neutral areas. On the embossing side of the carrier material a reflecting layer covers only surfaces with relief structures of the diffraction elements while the neutral areas which lie between are free of the reflecting layer and are therefore non-reflecting. If the security element is stuck in the form of a stamp onto the substrate and the carrier material is transparent, image portions, which are covered by the stamp, of a feature on the substrate can be discerned through the neutral areas.

  • Patent number: 5454306
    Abstract: A platform for supporting an engraving head in a manner accommodating translational movement without any associated rotation. The platform has a deck which is supported by a pair of flexible support columns. In operation the platform is situated alongside a rotating printing cylinder. The engraving head is mounted on the deck of the platform and is provided with a guide shoe which rides against the surface of the printing cylinder. As the cylinder rotates to angular positions having different radii, the engraving head responds with a purely linear reaction. Consequently the engraving head is able to engrave uniform-depth cavities in the surface of the printing cylinder. In two alternative embodiments the deck is driven by a resilient link arrangement which is coupled to a leadscrew and carriage assembly.

  • Patent number: 4726215
    Abstract: A method and apparatus is provided for stamping or printing identification indicia on a circular segment such as the flat portion of the head of a cap screw, bearing race, or stud end. The adjustable diameter stamp uses a plurality of segments which, when fitted together, form a cylinder or other polygonal shape which is held securely in a matching collet during the stamping operation. Variable diameter stamping is accomplished by using different sized stamping segments. Also, shims may be used to provide marking diameter adjustment. The preferred embodiment uses four wedge-shaped stamping segments.

  • Patent number: 4655267
    Abstract: A holder for embossing items of irregular cross-section is utilized in an embossing machine which has a pair of opposed platens with embossing dies mounted thereon. The holder includes a support plate positioned between the platens and having a central opening formed therein for receiving the die mounted on a first one of the platens. A pair of support blocks extends from the support plate toward the second platen on opposite sides of the opening and supports an article to be embossed over the opening. A plurality of guide posts extend from the first platen through apertures formed in the support plate and helical biasing springs encircle the guide posts to space the support plate and the article from the first die. As the second platen is moved toward the first platen, the second die engages the article and moves the article and the support plate against the biasing means to engage the article with the first die. Thus, equal pressure is applied to the article by the first and second dies.

  • Patent number: 4574693
    Abstract: The invention provides a seal press for use in embossing paper with a desired pattern using a die and a die counter. The seal press includes a housing, a seal set movable in the housing between inner and outer positions, and housing means biasing the seal set into an open position to receive the paper. A lever is pivotally connected to the housing and movable between upper and lower positions. First engagement means is provided between the lever and seal set with the lever and seal set in respective upper and forward positions, the lever being supported by the seal set in these positions to permit operation of the lever to close the seal set and emboss the paper. Also, second engagement means is provided between the lever and the seal set with the lever and seal set in respective lever and rearward positions for storage of the seal press. The seal set is biased towards the outer position and thereby through the second engagement means the lever is biased towards the lower position.

  • Patent number: 4319523
    Abstract: Apparatus supports each of several dies for concurrent application of equal displacement of all such dies relative to the to-be-embossed leather strip surface. The apparatus applies sufficient force to all of several dies, each of which provide different resistances to leather penetration to develop equal displacement of each of such dies into the leather and thereby provide embossed structure of uniform characteristic by all of said dies to produce a particular ornamental and decorative effect. The dies may be readily and rapidly replaced for a variety of names to different leather strips.
