Abstract
A film sticking method is disclosed in which the tip of the cutting portion of a sharp-pointed cutting member is caused to pierce a continuous film. The member is moved rightward and leftward across the direction of the feed of the film so that the film is cut off to a prescribed length. The cut-off film is stuck to a base plate. Also, a film sticking apparatus is disclosed which includes a film cutter for cutting off a continuous film to a prescribed length by moving a cutting member across the direction of the feed of the film and sticks the cut-off film to a base plate. The cutting member is formed so that it is sharp-pointed and has a cutting edge at least one side of edges of the member. The cutting edge can be moved backward and forward relative to the surface of the continuous film.
