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.

Abstract: A method and apparatus are disclosed for forming a tubular yarn carrier of the type adapted to have a yarn wound thereon to form a yarn package, and which includes an inturned annular end portion which is adapted to support the carrier on an internal spindle of a winding machine. The method of forming the inturned annular end portion includes inwardly turning one end of a tubular body member and so as to cause the end to be inwardly turned about an arc of about 180.degree., and while concurrently guiding the inwardly turned end radially outwardly into contact with the inside wall surface of the tubular member. The method results in the formation of a frusto-conical end portion which essentially locks against the inside wall surface of the carrier and thus prevents the inturned end portion from opening up during use.
