Abstract
Abstract Box capacitors are loaded onto an in-line track feeder with the capacitor leads extending downward between a pair of tracks. Vibration of the tracks moves the capacitors thereon so that the capacitor leads pass between the meshing teeth of a drive gear and an idler gear that is caused to turn by the former. The tracks are spaced from the gears to prevent damping of vibrations of the former. The leading edges of the teeth on the gears have a radius thereon for providing smooth feeding action of the capacitor leads between the gear teeth. The drive gear also has a chamfer on the top edges of the teeth thereof to reduce the possibility of jamming on components with bent leads. A disk is attached to the underside of the idler gear for cutting the component leads to a prescribed length as they pass between the disk and the drive gear. The ends of the teeth on the idler gear are truncated such that a cut lead is compressed into a valley between teeth on the drive gear to thereby straighten these leads.
