Abstract: A paper reel for yarn packages, and especially a paper reel of which the upper end is cut into a ladder like multiple layered end, the cut wall is folded inwardly twice, so that the end of the paper reel is folded onto a shoulder of the ladder like cut and is fixed, and the end of the paper reel will not warp nor has a paper rough edge. Both ends of the paper reel are processed to form a round shape, the ladder like portion has cut wall portions on its shoulders; the cut wall portions are folded to the shoulders one by one, the thickness formed by the cut wall portions folded back to the shoulders can afford a larger pressure when the paper reel is subjected to an axial force, thereby, the cut wall portions will not warp. The inner surface of the paper reel thereby is a smooth surface to be smoothly slipped over a rotation axle, yarn on the paper reel can thus be uninterruptedly sent out for weaving.
