Abstract
An apparatus for laminating a thin film to a base plate is disclosed in which the leading edge of the film is tentatively stuck to the surface of the plate at the leading edge of the plate in a base plate conveyance passage. A pair of pressure sticking rollers are put into contact with the leading edge of the film in a tentative sticking position and then rotated so that the plate is conveyed and the film is completely stuck to the plate. A wet roller unit provided on the passage, upstream of the position, to cause an air bubble preventive agent to cling to the plate. The agent is nearly uniformly fed from the interior of the wet roller unit to the outside surface thereof. The agent remaining on the film stuck to the plate is removed from the film, downstream of the pressure sticking roller unit.
