Systems and methods for applying a brake force during withdrawal of material from a bobbin

A method for imparting a force during operation of a wire bobbin, comprising:

• providing a wire bobbin disposed around a main shaft, wherein the main shaft is coupled to an adjustment assembly comprising an adjustment block and at least one adjustment spring, wherein 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;
• operating the wire bobbin in a first operational state, wherein there is a first quantity of wire around the bobbin in the first operational state, and wherein a first brake force is imparted to the main shaft in the first operational state;
• and
• operating the wire bobbin in a second operational state, wherein there is a second quantity of wire around the bobbin in the second operational state, the second quantity of wire being less than the first quantity due to withdrawal of wire from the bobbin,
• wherein a second brake force is imparted to the main shaft in the second operational state, the second brake force being less than the first brake force.

A system for imparting a force during operation of a wire bobbin, comprising:

• a main shaft for receiving a wire bobbin;
• a brake disk, wherein the brake disk is fixed relative to the main shaft such the brake disk rotates when the main shaft rotates;
• 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,
• wherein the adjustment block is 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 disk;
• and
• a brake assembly comprising a vertically-movable brake pad and at least one brake spring, wherein the brake spring provides a brake force on the brake pad such that the brake pad engages the brake disk.
