Abstract: A SYSTEM FOR HANDLING COMPRESSIBLE        ARTICLES SUCH AS LOADED BAGS        ABSTRACT OF THE DISCLOSURE           A system for handling a load of compressible items such as bags of glass fibre insulation includes a cart having a predetermined distance between its end walls but open on sides.  A forklift truck is provided with upright side walls movable towards and away from each other, and with means spanning the upper edges of the side walls, combined with fork elements in forming a generally rectangular load receiving compartment which corresponds to the generally rectangular load receiving compartment of the cart. When the load is lifted from the cart, the side walls can be actuated to contract the load by restricting the width of the load receiving compartment such as to allow the driving of the forklift truck into the cargo space of a tractor trailer or another suitable transport vehicle.  The unloading from the forklift truck is effected by a pusher plate known per se.  The advance in the art is in simplified structure of the equipment and in faster operation as the respective carts become available immediately upon the unloading of the load.  The structure of the cart itself is also simplified.

Abstract: ABSTRACT OF THE INVENTION An apparatus and method by which a single operator, at a single station, can pack pre-counted slugs of flat folded cartons, or trays, in one or more layers, in corrugated cases for discharge to a case taper several times faster than with manual packing by several operators.  The "flats" are advanced in a longitudinal path on a secondary apron of a stacker, erect on one edge, pre-counted and divided into slugs, so that the single operator can slide each slug longitudinally past a one-way back stop onto a transfer table.  The slug may be turned on its longitudinal axis by the operator for inspection and then compressed longitudinally by a ram against the back stop.  The operator has already been presented with a single, flat, tubular case, from a stack of such cases, with the leading flaps folded back, and has manually erected the case and inserted it in a case gripper preferably poised over the table, thereby closing the minor bottom closure flaps.  A start button brings the case gripper down to the level of the transfer table so that the operator can push the com-pressed slug laterally into the open case, resting on its side wall in the case gripper.  The case is automatically lowered to receive the next slug and when full, is turned on a longitudinal axis through 90° onto its bottom and discharged to a case taper while the case gripper returns to its original posi-tion above the level of the transfer table.
