ABSTRACT:
A device for storing a substantial length of an advancing strand including a pair of cantilevered mounted rolls each having a plurality of grooves. The rolls are spaced apart a predetermined distance so that the strand when threaded in a plurality of figure eight loops in the grooves at the forward ends of the rolls will migrate backwards along the rolls until the loops drop into staple positions in the grooves, thereby resulting in self-threading of the strand along the rolls.
