  • Patent number: 4226664
    Abstract: An apparatus for laminating articles with plastic of the type having supply rolls, pressure rollers and pull rollers through which a web of plastic is drawn. Heat shoes heat the plastic prior to the pressure rollers to cause an adhesive side to become fluent. The heat shoes have a large heating surface and are filled with sand. A plenum chamber directs cooling air onto the bonded web between the pressure rollers and pull rollers. The upper rollers are carried by a spring biased slide while the lower rollers are journaled to the frame. An eccentric mechanism mounted in the slide lifts the slide and upper rollers for threading and cleaning. A threaded linking member is attached between the slide and the top of the frame for incrementally lifting the upper pressure roller to allow single side lamination.
