  • Patent number: 7434508
    Abstract: Disclosed is a die press with a base, at least two cam members spaced from the base, an upper platen located between the base and the two cam members to define a space for a die, the upper platen being generally parallel to the base, the upper platen also being attached to the two cam members so that when the two cam members are actuated, the upper platen is moveable relative to the base, and a linkage connecting the two cam members so that the two cam members move in unison relative to each other when actuated.

  • Patent number: 6994024
    Abstract: Disclosed is an embossing system to be used with a die press. The embossing system includes a force transfer assembly, which comprises a first cover and an opposite second cover with the first and second covers being connected by a hinge. The force transfer assembly further includes a stencil and an opposing form positioned internal of the force transfer assembly. The stencil and the form are adapted to sandwich an embossing material, such as paper, between the stencil and the form. The embossing system further includes a layer of static vinyl that is located internally of one of the covers to secure the form to the internal side of one of the covers. The embossing system also utilizes an adhesive located on the cover opposite the cover with the vinyl to secure the stencil to the internal side of the opposite cover.
