More Information
Summary:An improved bobbin assembly is of a type utilized in wire wrapping machines and includes a plurality of bobbins rotatably mounted on a shaft. The shaft has a longitudinal slot so that a keyed washer mounted on the shaft between adjacent bobbins will not rotate. The keyed washers transfer braking force applied at the ends of the plurality of bobbins to each bobbin therein independently of and unaltered by the rotation of adjacent bobbins. A low coefficient of friction for the sliding surfaces of the bobbins and the keyed washers allows the bobbins to operate at a relatively high braking force so that the weight of the bobbins does not significantly effect the operation of the assembly.
