5.1.1 Tape Feed Lever Forward/Backward Stroke

The tape feed advance and retract stroke sends the tape forward.

The feeder moves the component to the pick-up position with the

forward stroke.

Square-motion type feeders however, advance the tape with the up

and down movement of the tape positioning claw, along with the

forward and backward motion of the tape feed lever.

• Drive Mechanism

The cam starts the tape feed cycle by advancing the lever on the

feeder. The stroke (fixed) depends on the cam curvature.
