ABSTRACT:
A lettuce head holding tray is defined in which both the upper tray layer and the lower tray layer are packed side-by-side at packing stations. At a carton loading station, two side-by-side arrays of plungers each are used for packing of discrete layers of the cartons. One array of plungers packs the bottom carton layer; the other array of plungers packs the top carton layer. Two cartons are disposed opened upwardly to the plunger array at the packing station; one carton is disposed to the bottom layer loading plunger array for packing of the bottom layer and the other carton--with its bottom layer previously packed--is disposed to the top layer loanding plunger array for packing of its top layer. The cartons--between the packing of the bottom layer and the packing of the top layer--are conveyed between positions underlying the plunger arrays. Thus each carton has is lower layer packed by the lower layer loading plunger array and then its top layer packed by the upper layer loading plunger array.
