Abstract
A film applying apparatus includes a presser roll reciprocally movable toward and away from the leading end portion of a tacking member to force an adhesive tape against a cover film of the laminated film while the laminated film is held by suction on a surface at the leading end portion of the tacking member. The surface of the tacking member includes a first and a second beveled surface. When the presser roll is advanced by a presser roll actuating device, it rolls on from the first beveled surface to a leading end of the second beveled surface during which time the adhesive tape is firmly adhered to the cover film. Then the presser roll is retracted and, at the same time, the adhesive tape is pulled by an adhesive-tape pullback device in a direction away from the tacking member whereupon the cover film adhered to the adhesive tape is separated from the laminated film. After the tacking is completed, a film tensioning device is driven to pull the laminated film backward. In this instance, since a slackening device is activated to slack the adhesive tape and the cover film adhered thereto, the laminated film can be readily pulled backward.
