ABSTRACT:
Disclosed herein is an apparatus for closely covering with a plastic film at least one surface of a base sheet such as identification card to improve the durability of the base sheet and to prevent any unauthorized alteration of information described thereon. The above apparatus includes a pair of conveying and pressing rollers and a heat radiation lamp incorporated therein to heat the circumference of at least one of the rollers. The base sheet and the plastic film overlaid are preheated by direct heat from the heat radiation lamp while being conveyed toward the pair of rollers, thereby achieving a high-speed processing and prevention of base sheet deformation. Also disclosed is an apparatus equipped with a heat transmission member along the base sheet feed path of a base sheet travelling path. The heat transmission member is adapted to present the base sheet and the plastic film, and may be formed by a part of a reflector plate.
