PURPOSE: To save manual working by a method wherein a paper selecting circuit and a paper retracting circuit are provided, and the selection of a specified roll- packing paper and the cutting of paper to a predetermined length can be automatically conducted, in a device for feeding a plurality of roll-packing papers.
CONSTITUTION: When a command for selecting a specified roll-packing paper 1n is fed by a roll-packing paper command circuit 9, a drive roll 3n for letting out and unwinding the packing paper 1n performs forward rotation (letting-out), to let out the end of the paper 1n of a predetermined length through a paper guide passage an, a common outlet b and a paper cutter 5. After letting out the predetermined length of paper, the cutter 5 is operated to cut out the predetermined length from the packing paper 4n. Then, the drive roll 3n for the packing paper 1n thus cut by the cutter 5 is rotated backward by operating a paper retracting circuit 6 to retract the end of the paper 1n to the guide passage an, resetting it to the original position.
