ABSTRACT:
A conveyor accumulates collapsed, flexible flat tubes into roughly aligned stacks which are transferred to a collator comprising an inclined tray-like receptacle mounted for multidirectional movement. The receptacle is simultaneously rotated and pivoted from a loading station to a discharge station while being rapidly reciprocated to vibrate the roughly stacked tubes. The combined effects of gravity and vibration urge the tubes to shift relative to each other into engagement with adjacent sidewalls of the tray to align the stack. A pallet mounted for multidirectional movement at the discharge station is automatically indexed to allow the aligned stacks to be deposited at preselected locations on the pallet.
