ABSTRACT:
This spool for ribbons, tapes, string, and the like comprises a plastic first cylinder, which ribbons or tapes are coiled around. A projecting flange along one edge of the cylinder helps to hold the ribbons or tapes coiled around it. Fitted inside the first cylinder is an adjustable second cylinder made of the same material. This adjustable second cylinder provides a second flange and includes a series of openings, each having a series of steps, any one of which can engage a projection rib on the inner surface of the first cylinder. The width between the two flanges is thereby determined, and the two cylinders may then be secured in the selected position.
