An apparatus for forming an enlarged, reinforced base on a yarn carrier includes a die for positioning around the outer surface of the yarn carrier having an inwardly folded over base portion. The die includes an annular recess for receiving the terminal portion of the yarn carrier therein, and the recess is shaped and sized to correspond to a desired shape of the enlarged base. A clamp holds the yarn carrier as a plunger is inserted into the terminal portion of the yarn carrier, and outwardly urges base of the yarn carrier into the recess of the die, molding the enlarged base on the yarn carrier. In another embodiment of the invention, the plunger and die are rotatable.
