摘要

PROBLEM TO BE SOLVED: To make it possible to apply lamination to heat-sensitive paper printed with hot-melt ink and to improve heat efficiency for heating a cover film without damaging the same. SOLUTION: A laminater for laminating a cover film F (F1, F2) coated with a hot-melt type self-adhesive having a low softening point at both surfaces or one surface of a sheet material S1 contains a non-heating pressure bonding roller 1 (1A, 1B) for bonding the cover film F and the sheet material S1 under heating and a preheating means 2 (2A, 2B) provided on this side of the pressure bonding roller 1 and heating the cover film F to low temp., and the preheating means 2 has a heating part for heating the cover film F, a fixed heater 2a having a closed outer shape containing the heating part and the endless belt member 2b arranged to the outer shape of the fixed heater 2a in a freely rotatable manner and rotated by the running of the cover film.
