ABSTRACT:
A process for manufacturing secure identification cards incorporating fiber optic elements which allow the generation of a binary encoded electro-optical signal uniquely identifying that card. Blank card stock will be made from a continuous web system in which the fibers 130 are aligned and brought to an appropriate spacing by combing 134 as they are drawn into the forming machine. The formed web stock is passed through bonding rollers 138 (either thermal or pressure) and then enters a take-up accumulator 150 and then to a punch where the blank forms are punched out of the web. The accumulator stage 150 compensates for the conversion from smooth motion through aligning, mating, and bonding areas to an intermittent motion at the punch area.
