Abstract
A film laminating apparatus, in which a continuous web of film has a plurality of heat-activation type film layers arranged thereon with predetermined spacing and is delivered together with a paper to a thermal transfer station to transfer the film layer onto the paper, includes an optical position indicator that is located ahead of each film layer on the web and that has optical transmission properties different from those of the web. An optical position detecting device is located at the entrance side of the transfer station, and drive rollers, pressure rollers, and a flat plate heater are operated in response to the output of the optical position detecting device to superpose the film layer onto the paper sheet so that the film covers less than the entire surface of the sheet.
