Trays are indexed at predetermined pitch on a tray conveyor. As the trays are conveyed, a turning guide engages a leading tray portion, turning the tray and urging it transversely downward and/or into buckets on an adjacent bucket conveyor or cartons on an adjacent carton conveyor. A cam is disposed rearward of each tray on the tray conveyors and the turning trays pivot about that cam. A hold-down prevents trays climbing over the turning guide. Pressure relief and tray indexing are provided upstream of the tray conveyor. Apparatus and methods are disclosed.
