ABSTRACT:
In producing a coreless toilet paper roll, a shaft is placed near an end portion of paper, and an adhesive is applied to either one of two sides of the paper relative to the shaft without providing to the shaft. The end of the paper is turned onto the other side over the shaft and is glued to the other side so that the end portion of the paper is fixed to the shaft. Thereafter, the shaft and the paper fixed at one end to the shaft are held among two take-up rollers and a pressure roller, and are rotated to wind the paper on the shaft. After winding the paper on the shaft, the shaft is removed from the roll and the paper is cut. The cutting of the paper and gluing the paper for the next rolling may be made at the same time.
