ABSTRACT:
An apparatus for working on the leads of electronic or electric components which is adapted to handle the components in a loose condition by way of a slide or in a bandoliered form. Bandoliered components have a regular spacing which is generally much smaller than the motion of tools in the direction of supply of the components, with the size of the motion being geared to the spacing between loosely supplied components. A tool group is moved backwards and forwards along the line of supply of the components, while the tools in the group are moved towards and away from each other. A limiting structure, which may be put into and out of operation, has the effect of overriding that is to say decreasing or completely stopping, the backward and forward motion of the tool group geared to the spacing of loose components. The limiting structure may have a screw-threaded rod cooperating with a cam follower so as to be steplessly moved towards and away from the overriding cam for the purpose of changing the degree of overriding.
