Patent number: 6283188Abstract: A two-sided card laminating apparatus simultaneously applies and bonds laminate sheets to opposing faces of a two-sided card substrate. The apparatus includes two opposing laminating assemblies symmetrically mounted in mirror image relation on opposing sides of a substrate supply path. Individual sheets of laminate are cut from webs of lamina and transferred onto the card substrate at a convergence zone disposed on the substrate supply path. Each of the laminating assemblies includes a web of lamina, a cutter, and nip rollers disposed between the web and the cutter. The nip rollers advance the web in an upstream direction through the cutter into engagement with a transfer roller. As the laminate exits the cutter, the leading edge is captured between the outer surface of the transfer roller and a laminate guide where it is grabbed by the outer surface of the transfer roller.Type: GrantFiled: September 25, 1998Date of Patent: September 4, 2001Assignee: Atlantek, Inc.Inventors: Raymond Maynard, Christian S. Rothwell

Patent number: 6094209Abstract: An apparatus for printing and laminating plastic cards consists of a thermal transfer printing station including ribbon and a thermal printhead for printing an image on a receptor surface of a receptor card, a laminating station including laminating film and a heated laminating roller mounted for engagement with said receptor surface of said receptor card during a laminating operation, and a guided carriage for transporting the receptor card beneath the printhead and the heated laminating roller. The carriage includes a resilient surface for receiving the receptor card with a receptor surface facing upwardly. The carriage is guided on a pair of rails to insure proper registration and tracking of the receptor card. The carriage is driven by a threaded rod which passes through a threaded bore in the carriage wherein rotation of the threaded rod by a motor causes movement of the carriage along the guide rails.Type: GrantFiled: September 29, 1997Date of Patent: July 25, 2000Assignee: Atlantek, Inc.Inventors: Edward A. Nardone, Paul R. Caron, Christian S. Rothwell, Harold D. Schofield, Gary Field

Patent number: 5637174Abstract: A system for the automated production of an identification card includes a two-part security media and apparatus for printing, laminating and die-cutting the security media to form discrete identification cards. The two-part security media includes a continuous web of an opaque backing film, and a continuous web of a clear cover film which acts as a receptor for receiving a thermally printed digital card image. A first thermal web printer is operative for printing a reversed digital card image onto an inner surface of the cover film adjacent a terminal end thereof. A second thermal web printer prints a second image onto the back of the backing film at a terminal end thereof. The printed ends of the backing and cover films are advanced to a cutting station wherein they are aligned in overlying relation and severed from their webs.Type: GrantFiled: April 10, 1995Date of Patent: June 10, 1997Assignee: Atlantek, Inc.Inventors: Gary Field, Paul V.
