Abstract
An apparatus of this invention includes first and second supply rolls of wrapping film sheets. The film sheet is fed from first supply roll to a wrapping machine. The distal end of the film sheet of the second supply roll is partially fixed by an adhesive tape. In this state, the film sheet cannot be fed from the second supply roll. The second supply roll can be rotated in the forward or reverse direction. The apparatus also includes a knife for cutting the adhesive tape of the second supply roll. When the remaining length of the film sheet fed from the first supply roll becomes short, the knife is brought into contact with the outer surface of the second supply roll. By utilizing the rotation of the roll, the knife is inserted under the distal end of the film sheet of the second supply roll. Thereafter, the knife is moved along the outer surface of the second supply roll in the axial direction thereof, thereby cutting the adhesive tape of the second supply roll. The apparatus also includes a belt conveyor for feeding the film sheet fed from the second supply roll to the feed path of the film sheet fed from the first supply roll.
