ABSTRACT:
A guiding and transporting arrangement employs opposed guide rails which have longitudinally extending guide structure associated therewith for slidably accommodating a lead frame between the guide rails, which guide rails are slidably supported on transversely extending guide rods, and are drivingly coupled together by a threaded screw arrangement which can be driven to accurately move the guide rails inwardly and outwardly to adjust the spacing therebetween. A conveyor is disposed for cooperation with the guide rails and is disposed below the lead frames to drivingly displace the lead frames longitudinally along the guide rails.
