ABSTRACT:
A feeding apparatus has a rotatable feed drum and first and second nip rollers movable into rolling contact with an outer circumferential surface of the feed drum by gravity. The first nip roller is made of a metal, and the second nip roller is made of rubber, so that the first nip roller exerts feeding forces smaller than feeding forces exerted by the second nip roller. A film that is fed by the feed drum in coaction with the first and second nip rollers is reliably prevented from being lifted off the outer circumferential surface of the feed drum.
