Claims

[Claims for Utility Model Registration] (1) The rotation of the wrapping arm pulls out the stretched film from the film roll toward the cargo, and the two large and small rollers held by the wrapping arm A film feeding device for a wrapping machine in which a stretched film is wound so that two rollers, large and small, are in pressure contact with a film roll at a distance and can rotate in opposite directions. (2) A feed-out roll whose speed is increased by the rotation of the wrapping arm is provided at the tip of the wrapping arm, and the stretched film is pulled out from the film roll toward the load via the feed-out roll, and the stretched film is drawn out toward the load. A film feeding device for a wrapping machine in which the speed of drawing out the film from the feeding roll is slower than the winding speed of the film.
