Abstract
PURPOSE: To provide a spiral roll which is cheap and does not rust, by spirally and tightly winding a PVC tape having a plurality of projecting ply lines, in special structure around a roll.
CONSTITUTION: A plurality of projecting ply lines 1, 2, 3 are provided at a specing on a PVC tape 6 so that the U-shaped projecting ply line 1 having a U-shaped slit 4 is located on the left edge of the tape, the lip-shaped projecting ply line 3 coincident with the U-shaped slit 4 of the ply line 1 is located on the right edge of the tape and an optional number of intermediate projecting ply lines 2 of the same height as the ply line 1 are located between the right and left edges. The PVC tape 6 is spirally and tightly wound around a roll 5 counterclockwise leftward from the center of the surface of the roll and clockwise rightward from the center, thereby providing the roll with the projecting PVC ply lines.
