ABSTRACT:
Apparatus for loading articles into trays where the articles are first separated into rows with a divider assembly, then separated into groups with a grouper assembly and then pushed onto a dead plate to form a load. Different divider and grouper assemblies are provided to make different load configurations. A tray blank is moved under the dead plate and pushed out from under the dead plate synchronously with the movement of the article load over the dead plate so that the article load is deposited on the tray blank. Thereafter, the flaps on the tray blank are folded to erect the tray around the group of articles. Mechanical folding mechanisms are provided to fold certain of the flaps on the tray without folding the other flaps. The method of loading the articles in the tray and forming the tray around the articles is also disclosed.
