In one embodiment, a system for imparting a force during operation of a wire bobbin comprises a main shaft for receiving a wire bobbin, and a brake element operably coupled to the main shaft. The system may further comprise an adjustment assembly comprising an adjustment block and at least one adjustment spring, wherein the at least one adjustment spring is biased to provide a force on the adjustment block in a vertically-upward direction. The adjustment block may be operably coupled to the main shaft, such that a mass of the main shaft imposed upon the adjustment block combined with resistance of the at least one adjustment spring determines a vertical position of the main shaft and the brake element. A brake assembly may provide a brake force on the brake element, wherein the brake force is imparted to the main shaft via the brake element.
