Abstract
A multi-part tray is provided to carry a plurality of objects in precise and accurate array through a process device. The tray parts are each fastened to a flexible plate and also to a conveyor. The conveyor is caused to travel a circuitous route around convex curves which thereupon splay the tray parts apart beneath a loading station and also beneath an unloading station where the objects are slidably moved onto or removed form the tray. A plurality of loading and unloading fingers slide in corresponding grooves in the bottoms of the tray-parts and beneath the objects.
