Abstract

A laminating machine of the type which laminates documents between sheets of plastic or a document to a substrate comprising a housing together with a first set of rolls within the housing adapted to guide the material to be laminated between upper and lower heating platens and a second set of rolls within the housing arranged to receive the material from the platens. The first set of rolls, the platens and the second set of rolls define a passage through the housing. End supports for the rolls are provided in the housing defines. The rolls are rotatably supported between the end supports. A drive motor is connected to one of the rolls at one of the end supports, and gearing means are positioned on the rolls at the other of the end supports for transmitting rotation of the driven roll to the other rolls. The upper rolls of each pair are journaled in bearing arms which are pivoted to the end supports to permit acceptance of thick substrates. Auxiliary drive means are provided to maintain all rolls in synchronization when a thick substrate causes the gears to move out of mesh.
