  • Method for fabricating plastic cards
    Patent number: 6019268
    Abstract: A method to fabricate plastic cards is disclosed. A substrate tape is perforated with evenly spaced holes, and when placed in a working station, positioning pins engage into the holes. The spacing between two sets of pins is then slightly increased thereby tensioning the tape without stretching it thereby providing for highly accurate alignment.

  • System for processing a web of plastic material
    Patent number: 5779125
    Abstract: In a system for processing a plastic web plural work stations are disposed on an elongated beam. The web is provided with positioning holes cooperating with complementary pins in at least one work station. As the distance spacing allocated holes may vary due to shrinking, the beam may be bent about a transverse axis into a ring sector shape thereby adapting the pin distances to the actual hole distances.
