ABSTRACT:
A laminating machine of the type which laminates documents between sheets of plastic or on a substrate comprising a housing, first and second sets of upper and lower rolls within said housing having end shafts, one of the sets of rolls arranged to receive material to be laminated and move the material to the other of the sets of rolls, spaced apart end supports are in housing rotatably supporting the end shafts, drive means are connected to the lower rolls of each pair, to drive the lower rolls, the upper rolls of each pair are mounted in the end supports to move upwardly to accommodate material of variable thickness, resilient power transmission means are connected between the upper rolls and the lower rolls and driven from the lower rolls to maintain synchronization of rotation of the upper rolls with the lower rolls and to bias the upper rolls downwardly while permitting the upper rolls to move upwardly to an extent dependent on the thickness of material passing between the pairs of rolls.
