FILM PASTING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent wrinkles from developing after being pasted to a board by a method wherein a film is pressed in uniform state and temperature distribution against a lamination roll in a film pasting device. SOLUTION: By means of a gas spraying member 28 provided on the inlet side of a lamination roll 22B in a film pasting device 10, pressurized gas is sprayed through a plurality of small holes on the surface of a recessed circular surface 30 having nearly the same radius as that of the lamination roll 22B against a laminate film 14 so as to realize the state of the lamination film 14 being fairly pressed against the lamination roll 22B and temperature- distributed over it. At this time, the small holes are arranged in three or more rows to the peripheral direction of the lamination roll under the condition that not a plurality of small holes are present in a section normal to the center axis of the lamination roll 22B.
