Abstract

A wire feeder comprises a feedroll with through slots that open into a bore and that extend between the feedroll ends. The feedroll has blind slots in the ends that also open into the bore. A shaft on the wire feeder has a radial pin. The feedroll is assembled on the shaft by angularly aligning the through slots with the pin and pushing the feedroll onto the shaft against a spring until the feedroll is past the pin. The feedroll is rotated on the shaft until the blind slots align with the pin. Then the feedroll is released to enable the blind slots to engage the pin under the force of the spring. The feedroll may be assembled to the shaft either in a manner that takes up any end play of the shaft, or that enables the feedroll and shaft to float through the end play.
