ABSTRACT:
Disclosed is a device for wrapping up the ends of a roll in a wrapping paper which has been wrapped to encircle the roll and which being longer than the roll extends cylindrically from both ends thereof, which device is characterized by having a plurality of tucking members disposed at given intervals on the outer peripheral surface of the wrapping paper extending from the ends of the roll and by having a plurality of projecting members disposed on the inner peripheral surface of the wrapping paper spaced to fall one between each adjacent pair of tucking members. By moving the plurality of tucking members toward the center of the roll and at the same time gradually drawing in the plurality of projecting members, the extended portion of wrapping paper is formed with alternate ridge portions and groove portions and is pressed onto the ends of the roll. The portions of the wrapping paper which stop up the center hole of the roll when the formed ridge portions are flattened in one direction are pushed into the center hole of the roll.
