ABSTRACT:
A tension compensator for use on a package winder has two spaced pins projecting from a rotatable member, the pins being parallel to the axis. The member is biased to rotate in a predetermined direction to a stop, so that a strand passed between and over said pins in zig-zag fashion moves the pins against the bias to straighten the strand under higher tension and permits the bias to move the pins to store the strand under lower tension. The compensator is made self-threading by providing a ramp to deflect the strand over the end of one pin when traversing past the pin in one direction, and a strand-guide to deflect the strand over the extremities of both pins and the ramp on the initial traversal of the strand in the opposite direction.
