A light-weight side gusset for a bag is manufactured from a formed composite frame having a peripheral raised region and a depressed central region. An opening is formed through the depressed central region to form a relatively narrow border portion around the inner periphery of the raised region. A central panel corresponding in configuration to the outline of the depressed region is attached to the border portion of the depressed region to cover the opening therethrough. The composite frame is made up of a moldable substrate, e.g. ethyl vinyl acetate foam, an outer layer wear-resistant material, e.g., high-denier nylon or poly/nylon combination, and, preferably, an inner adherent layer, e.g., the loop half of a hook-and-loop fabric. A complete bag is assembled by securing two such gussets to the body of the bag. A drop-in liner is attached to the inner surfaces of the gussets to line the interior of the bag.

1. A method of manufacturing a gusset for a bag, comprising the steps of:(a) providing a substrate of moldable synthetic material; (b) adhering a non-stretchable, wear-resistant material to one surface of the substrate; (c) making at least one incision through a central region of at least the wear-r
1. A method of manufacturing a gusset for a bag, comprising the steps of:(a) providing a substrate of moldable synthetic material; (b) adhering a non-stretchable, wear-resistant material to one surface of the substrate; (c) making at least one incision through a central region of at least the wear-resistant material; (d) molding the substrate and adhered wear-resistant material to form a composite frame blank having a raised peripheral region surrounding a depressed central region, with the wear-resistant material on the raised peripheral region side of the frame blank and wherein the depressed central region has an outline; (e) cutting an opening through the depressed central region of the frame blank to form a border portion of the depressed central region around an interior periphery of the raised peripheral region; (f) providing a central panel substantially corresponding in configuration to the outline of the depressed central region; and (g) securing the central panel to the border portion of the depressed central region of the frame and covering the opening therethrough. 2. The method of claim 1, wherein the wear-resistant material is a high-denier content fabric.3. The method of claim 2, wherein the wear-resistant material is a nylon or poly/nylon combination.4. The method of claim 1, wherein the wear-resistant material is a non-woven synthetic material.5. The method of claim 1, wherein the moldable synthetic material of the substrate is ethyl vinyl acetate foam.6. The method of claim 1, further comprising the step of molding in the raised peripheral region of the frame blank at least one indentation corresponding in configuration to an external member to be mounted on the frame.7. The method of claim 1, further comprising the step of trimming any excess material from the exterior periphery of the raised peripheral region of the frame blank.8. The method of claim 1, wherein step (f) comprises the steps of:(1) providing an inner stiffening member, an intermediate cushioning member, and an outer covering fabric; and (2) assembling the stiffening member, the cushioning member and the outer covering fabric together to form an assembly comprising said central panel. 9. The method of claim 1, further comprising the step of (h), prior to step (c), adhering an adherent material to a surface of the substrate opposite to the surface of the substrate adhered to the non-stretchable, wear-resistant material.10. The method of claim 9, wherein the adherent material comprises one half of a hook-and-loop fastener fabric.11. The method of claim 10, wherein the one half is the loop half of the hook-and-loop fastener.12. A method of assembling a bag, comprising the steps of(a) providing a substrate of moldable synthetic material; (b) adhering a non-stretchable, wear-resistant material to one surface of the substrate; (c) making at least one incision through a central region of at least the wear-resistant material; (d) molding the substrate and adhered wear-resistant material to form a composite frame blank having a raised peripheral region surrounding a depressed central region, with the wear-resistant material on the raised peripheral region side of the frame blank and wherein the depressed central region has an outline; (e) cutting an opening through the depressed central region of the frame blank to form a border portion of the depressed central region around an interior periphery of the raised peripheral region; (f) providing a central panel substantially corresponding in configuration to the outline of the depressed central region; (g) securing the central panel to the border portion of the depressed central region of the frame and covering the opening therethrough; (h) providing a body of the bag having a top, a bottom, a front, a back and two ends; and (i) attaching a gusset manufactured in accordance with steps (a)-(g) to each end of the bag body to form the sides of the bag. 13. The method of claim 12, further comprising the step of (j), prior to step (c), adhering an adherent material to a surface of the substrate opposite to the surface of the substrate adhere to the non-stretchable, wear-resistant material.14. The method of claim 13, further comprising the steps of:(k) providing a liner for the bag, the liner having a portion for overlying an inner side of each gusset, each said liner portion being adapted, at least in a portion to overlie the border portion of the depressed region of the substrate of at least one of said gusset, to adhere to the adherent material on the substrate; and (l) attaching the liner to at least one of said gussets by pressing said overlying portion of the liner into contact with the adherent material on the substrate. 15. The method of claim 14, wherein each said liner portion is further adapted, in the portion thereof overlying at least in part the region of the gusset adjacent the top, bottom and back of the bag, to adhere to the adherent material on the substrate of at least one of said gussets, and wherein step (l) further comprises pressing said further portion of the liner into contact with the adherent material on the opposed region of at least one of said gussets.16. The method of claim 15, wherein the adherent material on the substrate of each gusset is the loop half of a hook-and-loop fabric; and at least said portions of the liner being adapted to adhere to the adherent material on the substrate of at least one of said gussets have affixed thereto the hook half of the hook-and-loop fabric.17. The method of claim 12, wherein at least the front and the back of the body of the bag are comprised of a soft fabric.18. The method of claim 17, wherein the soft fabric is a nylon or poly/nylon combination.19. The method of claim 12, wherein the wear-resistant material of step (b) is a high-denier content fabric.20. The method of claim 19, wherein the wear-resistant material is a nylon or poly/nylon combination.21. The method of claim 12, wherein the moldable synthetic material of step (a) is ethyl vinyl acetate.22. The method of claim 12, further comprising the step of molding at least one indentation into the raised region of each gusset frame corresponding to an external member to be mounted on the frame.23. The method of claim 22, further comprising mounting said external member in said at least one indentation in the gusset frame.24. The method of claim 23, wherein said at least one member is a wheel assembly of the bag.25. The method of claim 12, further comprising the step of trimming any excess material from the exterior periphery of the raised region of the frame blank.
