Abstract: An apparatus for sealing a box having four top flaps initially disposed in an open position. The apparatus includes a conveying system for conveying the box from a first end of the apparatus to a second end of the apparatus. The apparatus also includes a flap folding system for folding the top flaps of the box into folded and horizontal positions as the box is conveyed from a first end of the apparatus to a second end of the apparatus. The flap folding system has a first flap folding member configured to fold a fourth top flap of the box, a second flap folding member configured to fold a second top flap of the box, and a pair of oppositely disposed side flap folding members configured to fold a first and third top flaps of the box so as to abut each other. A tape dispensing system is configured to dispense tape across at least a portion of the third and fourth top flaps of the box in order to maintain the third and fourth top flaps in abutment with each other, thereby sealing the box.

Abstract: A belt mounted support and a group of bags for support on the belt mounted support is used in the harvest of produce. The belt mounted support includes a tube and a belt mounting loop connected to the tube. A bag supporting rod is threaded through the tube to freely rotate with two hooked bag supporting ends. A group of bags is supported on the belt mounted support, each bag formed from perforate plastic sheet. Each individual bag has a front rectilinear panel, a rear and larger rectilinear panel, and a folded gusset at a bottom of the bag folded upward between the front rectilinear panel and the rear and larger rectilinear panel. Logo on the bags is formed from an outside of the bag to be read from an inside of the bag whereby the bag is manufactured in an inverted disposition with respect to the logo. The group of bags is registered one to another at a rear panel protrusion.

Abstract: An arm and cradle apparatus is disclosed for receiving empty trays from an upper conveyor having empty lettuce holding and transporting trays, lowering the received empty tray to an angular disposition in which it can most conveniently be packed, and finally off loading the packed full tray to a lower conveyor having full lettuce holding trays thereon for plunging to cartons. The arm and cradle apparatus is mechanically passive in that all movements of the trays to and from the arm and cradle apparatus are either worker assisted or occur under the natural gravity biased movement of the arm and cradle apparatus.

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.

Abstract: A lettuce packing machine for the packing of heads of lettuce in corrugated, carboard cartons is disclosed. A lettuce head holding tray is loaded with lettuce. Thereafter, the tray is utilized to pack cartons. The lettuce head holding trays has discrete lettuce receiving cells upwardly exposed. Each tray contains four columns of cells, each column of cells being three wide for a capacity of 12 heads of lettuce. Each discrete lettuce receiving cell in the tray is defined by four semirigid, flexible sides, which sides extend downwardly and inwardly, are elastically biased and form an inverted pyramid-like profile truncated at an open bottom. The lettuce head holding tray is loaded at a picking station and conveyed to a packing station. When the lettuce head holding tray arrives at the packing station, a packing apparatus having discrete plungers--one for each cell--unloads the tray overlying a box to be packed.
