Methods, devices and computer program products automatically package an object in a covering material such as casing and/or netting by: (a) automatically pushing at least one object through a product chute; (b) pulling a covering material upstream of the product chute off an exterior surface of the product chute to automatically enclose the object in the covering material as the object exits the product chute; and (c) applying a clip to the covering material to secure the object in the packing material.

That which is claimed is: 1. A system for pushing product through a product chute that dispenses covering material from an outer surface thereof so that the covering material receives a product discharged from the product chute, comprising: a product chute having an open through cavity; a pusher head having a forward portion with a pin extending outwardly therefrom so that a sharp end of the pin extends in a downstream direction, the pusher head configured and sized to enter into the product chute and push a food object undergoing packaging through the product chute; a pusher actuation cylinder attached to the pusher head assembly to direct the pusher head assembly to automatically and controllably repetitively reciprocate between a downstream position and an upstream position, wherein, in operation, the product emerges from the product chute in a substantially uncompressed shape to be encased in a covering material held over an exterior portion of the product chute; and a clipper mechanism in communication with the product chute whereby the clipper mechanism applies at least one clip to a leading and/or trailing end portion of the covering material. 2. A system according to claim 1, further comprising a pair of axially extending guide rods held on opposing sides of the pusher cylinder and having a length that is substantially coextensive to that of the pusher cylinder, wherein the guide rods are configured to move in concert with the pusher cylinder both in a forward and rearward stroke of a stroke cycle associated with the reciprocating movement of the pusher head assembly, and wherein the pusher cylinder and guide rods reside laterally spaced apart from each other across a width of the chute in a horizontal orientation above a floor of the chute. 3. A system according to claim 1, wherein the pusher head comprises a channel that angles inwardly from two outer side portions to a substantially planar medial portion, and wherein the pin is a single pin that is attached to and extends outwardly in a downstream direction from the planar medial portion. 4. A system according to claim 3, wherein the pin has a length such that a forwardmost portion resides proximate a boundary defined by a line extending across the forwardmost edge of the two outer side portions, and wherein each outer side portion of the channel is connected to a respective axially extending guidewalls. 5. A system according to claim 4, wherein the pin resides behind the boundary. 6. A system according to claim 1, wherein the pusher actuation cylinder is in communication with a pressure regulator that is configured to allow the product pusher to automatically serially push products through the product chute then retract to reside upstream of the product chute with a major portion of the pusher actuation cylinder exposed to environmental conditions, wherein the actuation cylinder operates with a substantially fixed pressure of between about 50-80 psi to push respective products through the chute using a continuous push stroke cycle. 7. A system according to claim 1, further comprising: at least one pressure regulator in communication with the actuation cylinder and in communication with a pressurized air supply; and a plurality of three-way valves in communication with the pressure regulator and/or actuation cylinder, one three-way valve residing at first and second opposing end portions of the actuation cylinder. 8. A system according to claim 1, wherein the product pusher comprises a pair of elongate guide rods, at least one being disposed on each side of an actuation rod that is attached to the actuation cylinder, the actuation rod and guide rods being attached to the pusher head and spaced apart from each other over a width direction of the chute, wherein the actuation rod, guide rods and pusher head are configured to reciprocally travel substantially in concert in and out of the product chute, the system further comprising a controller that electronically directs the pusher head to controllably automatically advance into and retract from the product chute to thereby advance a product from a position upstream of the product chute, through the product chute and out of the discharge end portion of the product chute. 9. A system according to claim 1, wherein the pin is a single pin held in a medial location of the pusher head and is configured to pierce and releasably enter a target product. 10. A system according to claim 1, wherein the product pusher assembly is configured to push edible food items. 11. A system according to claim 1, wherein the product chute is a netting chute holding a sleeve of netting thereon wherein the product pusher assembly is configured to push meat through the netting chute. 12. A system according to claim 1, wherein the pin has a width that is substantially smaller than the pusher head. 13. A system according to claim 1, wherein the pin is statically affixed to the pusher head. 14. A system according to claim 1, wherein the food object and chute are sized and configured so that the food object travels snugly through the chute. 15. A system according to claim 1, wherein the product chute cavity is oversized relative to the food object and the food object travels uncompressed through the chute. 16. A system with a product pusher assembly for pushing product through a product chute that dispenses netting material from an outer surface thereof so that the netting material receives a product discharged from the product chute, comprising: a product chute having an open through cavity; a sleeve of netting material held over an exterior surface of the product chute; a pusher head having a forward portion with a piercing member with a sharp tapered forwardly extending end portion extending outwardly therefrom, the pusher head configured and sized to enter into the product chute and push an edible food object undergoing packaging through the product chute; a pusher actuation cylinder attached to the pusher head assembly to direct the pusher head assembly to automatically and controllably repetitively reciprocate between a downstream position and an upstream position, wherein, in operation, the food object emerges from the product chute to be encased in the netting material; and a clipper mechanism in communication with the product chute whereby the clipper mechanism applies at least one clip to a leading and/or trailing end portion of the netting material. 17. A system according to claim 16, wherein the piercing member has a width that is substantially smaller than the pusher head. 18. A system according to claim 16, wherein the piercing member is statically affixed to the pusher head and moves in concert therewith. 19. A system according to claim 16, wherein the edible food object and chute are sized and configured so that the food object travels snugly through the chute. 20. A system according to claim 16, wherein the product chute cavity is oversized relative to the edible food object and the food object travels uncompressed through the chute.
