A quick change module operable for being removably attached to and extending below a forming tube of a conventional vertical form, fill, and seal machine to produce a wide assortment of differently sized vertical stand-up pouches or gusseted flat bottom bags. The quick change module comprises at least one pair of adjustable forming plates located below the forming tube. The lateral distance between each pair of forming plates can be adjusted by shifting the position of each forming plate along a corresponding slotted bracket. A gusseting mechanism mounted to the frame of the machine can be positioned between each pair of forming plates imparting a vertical crease along the length of the bag while it is being formed and advanced down the forming tube of the machine. By adjusting the lateral separation of the forming plates, the size of the vertical crease can be adjusted such that the resulting gusseted base is increased or decreased in proportion to size of the resulting package, thereby enhancing the overall stability of the package when placed on display.

The invention claimed is: 1. An improved vertical form, fill, and seal machine having a forming tube, said improvement comprising: a quick-change module capable of being removably attached to and extending below said forming tube, said module comprising a pair of slotted brackets oriented at a converging angle to one another; a pair of forming plates corresponding to and selectively attached to said pair of slotted brackets, wherein each forming plate can be selectively configured and attached at more than one position along its corresponding bracket; and a tension bar positioned on said module at a location approximately opposite from said pair of forming plates; and at least one gusseting mechanism attached to said form, fill, and seal machine and capable of being positioned between said of forming plates. 2. The improved vertical form, fill, and seal machine of claim 1, wherein each of said slotted brackets is pivotally attached to said module by a horizontal hinge. 3. The improved vertical form, fill, and seal machine of claim 2, wherein said hinges allow for said pair of forming plates to rotate about said hinges towards each other to compensate for the narrowing of a packaging tube during formation of a transverse seal. 4. The improved vertical form, fill, and seal machine of claim 2, wherein each of said forming plates comprise a planar surface having a tang section at one end for attaching to said corresponding slotted bracket, said tang section being offset angularly from said planar surface to compensate for said converging angle thereby allowing each planar face to rotate about a pivotal axis of said hinge. 5. The improved vertical form, fill, and seal machine of claim 2, wherein each of said horizontal hinges comprise shoulder element pivotally attached to a bolt, wherein said bolts are fixably attached to said module. 6. The improved vertical form, fill, and seal machine of claim 5, wherein each of said shoulder elements includes a counterbalancing weight bias. 7. The improved vertical form, fill, and seal machine of claim 1, wherein said converging angle ranges from about 30째 to about 45째. 8. The improved vertical form, fill, and seal machine of claim 1, wherein said quick-change module is attachable to said forming tube by inserting tabs that are integral to said forming tube into corresponding holes that are integral to said quick-change module. 9. The improved vertical form, fill, and seal machine of claim 1, further comprising a diverter tongue attached to said module, said tongue being operable to shield said slotted brackets and forming plates from a food product dispensed down said forming tube during an operation. 10. The improved vertical form, fill, and seal machine of claim 9, wherein said diverter tongue aligns with a diverter wall in said forming tube to form a gas flushing channel. 11. The improved vertical form, fill, and seal machine of claim 1, wherein said gusseting mechanism comprises a pivoting tucker mechanism or an adjustable, stationary tucker bar. 12. A quick-change module capable of being removably attached to and extending below a forming tube of a vertical form, fill, and seal machine, comprising: a tubular module body having a periphery which corresponds to said forming tube's periphery; a pair of slotted brackets attached to and extending below said module body, said slotted brackets being oriented at a converging angle to one another; a pair of forming plates corresponding to and selectively attached to said pair of slotted brackets, wherein each forming plate can be selectively configured and attached at more than one position along its corresponding slotted bracket; and a tension bar attached to and extending below said module body, said tension bar positioned on an opposing side of said module body from said pair of forming plates. 13. The quick-change module of claim 12, wherein each of said slotted brackets is pivotally attached to said module body by a horizontal hinge. 14. The quick-change module of claim 13, wherein said hinges allow for said pair of forming plates to rotate about said hinges towards each other to compensate for the narrowing of a packaging tube during formation of a transverse seal. 15. The quick-change module of claim 13, wherein each of said forming plates comprise a planar surface having a tang section at one end for attaching to said corresponding slotted bracket, said tang section being offset angularly from said planar surface to compensate for said converging angle thereby allowing each planar face to rotate about a pivotal axis of said hinge. 16. The quick-change module of claim 13, wherein each of said horizontal hinges comprise shoulder element pivotally attached to a bolt, wherein said bolts are fixably attached to said module body. 17. The quick-change module of claim 16, wherein each of said shoulder elements includes a counterbalancing weight bias. 18. The quick-change module of claim 12, wherein said converging angle ranges from about 30째 to about 45째. 19. The quick-change module of claim 12, wherein said module body is attachable to said forming tube by inserting tabs that are integral to said forming tube into corresponding holes that are integral to said module body. 20. The quick-change module of claim 12, further comprising a diverter tongue pivotally attached to said module, said tongue being operable to shield said slotted brackets and forming plates from a food product dispensed down said forming tube during an operation. 21. The quick-change module of claim 20, wherein said diverter tongue aligns with a diverter wall in said forming tube to form a gas flushing channel.
