Abstract
Abstract A machine for simultaneously straightening leads extending in opposite directions from the central portion of a member such as a diode, including a base, a plurality of substantially parallel roll sets mounted on said base for defining a first space for receiving the leads for simultaneously rolling said leads therebetween, each of said roll sets consisting of first and second coaxial series of rolls with a second space between the first and second series with the rolls of each series being mounted in a cantilevered manner, a conveyor in the form of a feed wheel having pivotally mounted arms for receiving a workpiece proximate the central portion thereof at a pick-up station and carrying the member to said first space and for holding said member at said first space while the leads are straightened and thereafter carrying the member to a station where it is removed from the feed wheel, the mounting of the roll sets in a cantilevered manner permitting the feed wheel and related feed apparatus to be located in the second spaces between the axially aligned cantilevered roll sets. The feed wheel can be driven in an intermittent stepwise manner, as by a Geneva gear mechanism, or, alternatively, the feed wheel can be driven by a gearing arrangement at a substantially continuous rate of speed because the arm carrying the workpiece is mounted to yield while the workpiece is being momentarily stopped at the work station.
