Abstract: A strip stacker for stacking in parallel planes, plate like strips of electronic components. The machine has a trap door onto which the plate like strips are placed in succession. Each time a strip is placed on the trap door its position is sensed by an electronic eye which actuates a motor to swing the trap door down allowing the strip to fall down a slide with its lower edge into a tray. A compacter bar is slideably supported in the tray and two locating pins project into the tray to hold the strips already stacked in position as the compacter bar retracts. Each time a strip falls from the trap door the compacter bar is retracted, the pins retract, and the compacter bar extends forcing the strip against the end until the fallen strip is in position behind the locating pins and pushing the tray down the slides. The locating pins extend holding the last strip against its predecessors. When the tray is full it will be at its lower extreme position and will be removed.

Abstract: The system disclosed herein is a high speed method and apparatus for presenting parts to a laser beam for marking the parts. The apparatus is capable of feeding at adjustable rates, various sizes and configuration of parts in strip form such as electronic component, a die cut strip or on lead frames.
