Abstract
A textile core for winding a package of yarn. The textile core includes a tubular body having opposed ends and a bodywall formed of a paperboard material. To prevent slippage of a transfer bunch or tail formed on the core during winding processes, a plurality of spaced, discreet perforations are provided on the exterior periphery of the tubular body adjacent at least one end thereof. The perforations extend substantially around the circumferential periphery of the tubular body, and extend radially into the bodywall for only a portion of the thickness thereof. A projection adjacent each perforation is also provided, extending radially outwardly from the bodywall and formed of paperboard material removed from the adjacent perforation. The projections are capable of frictionally engaging at least one yarn winding formed on the top thereof and thus prevent slippage of the transfer tail.
