ABSTRACT:
Rapidly descending articles are decelerated in a segmented walled mechanism which alternately decreases in cross-sectional area to decelerate and restrain an article and subsequently increases in cross-sectional area to permit the article to fall safely to a reception device, such as a conveyor, below. The decrease in cross-sectional area is synchronized with the delivery of the article from an associated fabrication device. The mechanism also includes a synchronously oscillating receiving tube which alternately tracks one moving discharge site on the fabrication device and then returns to engage and track an adjacent discharge site. Orientation of the article is maintained as it passes through the cross-sectional area and onto the conveyor.
