Claims

[Claims for Utility Model Registration] A large number of small holes 2 are formed in a rotating roll 1, and a film F that partially contacts the roll surface is brought into close contact with the roll 1 by sucking gas from inside the roll 1. In a film feeding roll device, there is a pipe 4 that does not rotate inside the rotating roll 1.
The pipe 4 is opened along the circumferential direction at a point corresponding to the contact point between the roll 1 and the film F, and a long hole 7 is formed in the roll 1 at substantially the same angle as the contact angle between the roll 1 and the film F. A film feeding roll device characterized in that it is formed to correspond to the small hole 2.
