Abstract: This invention provides a wrinkle-proof mechanism for a paper roll supply to a cutter in which a plurality of paper rolls are arranged linearly in two vertical stages and whereby the paper strip unwound from any one of said paper rolls excluding the foremost positioned roll is guided preferably linearly over the forwardly positioned paper roll or rolls to a fixed roller so that said paper strip will not hold or embrace the forwardly positioned paper roll or rolls. Movable rollers are provided between the foremost positioned paper rolls and said fixed roller, said movable rollers being arranged to move downward in proportion to the diameter of the paper roll decrease so that the angle at which said paper strip holds the foremost positioned paper roll is sharply reduced to thereby keep the paper strip free of wrinkles and reduce the braking force of the foremost paper roll.
