Abstract
A film applying apparatus includes upper and lower mounting members for upper and lower suction plates, which are driven by a servomotor through pinions and racks to move the suction plates to positions located at a prescribed distance from a base plate. Thereafter, power is applied to the upper and lower mounting members by common pneumatic cylinders to move the upper and lower suction plates from their positions toward the base plate to tentatively apply films to the upper and lower sides of the base plate. The tentative applying forces of the upper and lower suction plates are equal to each other. After the tentative film application, the suction plates are quickly moved away from the base plate. A film applying method also is provided. With this structure and method, support members for first and second film feed members are dispensed with to reduce the operation time of the film applying apparatus and to simplify the structure thereof, and power from common drivers to the film feed members is applied to equalize the tentative applying forces to the suction plates.
