Abstract
A card substrate laminating device includes a transfer ribbon and a transfer roller. The transfer ribbon includes a carrier layer and a transfer layer attached to the carrier layer. The transfer roller is configured to heat and transfer a portion of the transfer layer from the carrier layer to a surface of a card substrate. The transfer roller has a circumference that is less than one-half of a length of the card substrate.
Claims17
A card substrate laminating device comprising:
- a transfer ribbon comprising a carrier layer and a transfer layer attached to the carrier layer;
- and
- a transfer roller configured to heat and transfer a portion of the transfer layer from the carrier layer to a surface of a card substrate;
- wherein the transfer roller has a circumference that is less than one-half of a length of the card substrate and a heat capacity of less than 7 J/° C. per inch length.

A method of laminating a card substrate comprising:
- feeding a card substrate along a processing path using a transport mechanism;
- and
- transferring a portion of a transfer layer of a transfer ribbon to a surface of the card substrate using a transfer roller comprising steps of:
- heating the transfer roller from an ambient temperature to a laminating temperature within 40 seconds;
- pressing the portion of the transfer layer against the surface of the card substrate using the transfer roller while the transfer roller is at a temperature that is greater than or equal to the laminating temperature;
- rotating the transfer roller about a central axis at least two times during the pressing step;
- and
- removing a carrier layer of the transfer ribbon from the portion of the transfer layer.
