A paper board blank is formed into a tray having a double glued side wall construction for providing a desirable strength to the tray. A platen drives the blank through forming rails which fold the blank into a partially formed tray having bottom, end and side walls, and inside corner supports formed about the platen. After the platen is retracted, a first folding arm folds a top wall portion to a position generally parallel to the bottom panel. A second folding arm then folds end fold portions of outside corner supports into a passage formed between a compression plate and a fixed guide plate, wherein the fixed guide plate provides a guiding surface. The compression plate is then biased against each of the side fold portions for compressing the side fold portions against the side panels to form the tray.
