Abstract
A method of manufacturing a yarn carrier designed to accommodate the tail of the yarn to be wound therearound without severing. A tube is wound from paper and a portion severed therefrom, producing a burr. A subsequent grinding operation removes the burr, and forms a beveled region having loose fibers to cushion the yarn against a winding mandrel.
