An improved double twist wire bunching machine has a reel consisting of at least one disk on which a plurality of wire spools can be mounted with parallel horizontal axes. An improved brake tensioning system includes a brake shoe assembly associated with each spool, a tension spring connected to each brake shoe assembly, an actuator ring rotationally mounted on the creel and engaging the ends of each tension spring and a contacting means associated with one wire spool sensitive to the amount of wire on the spool such that as the amount of wire on the spool is decreasing, the contacting means causes the actuator ring to rotate through a proportionate angle decreasing the tension in the tension springs to thereby proportionally and uniformly decrease the brake tension on the spools and thereby maintain a constant tension in the wires being bunched.
