A vertical form fill and seal system for making flat-bottom stand-up bags comprising: a support rod or a spindle that rotatably supports an elongated sheet of material (S) defined by a plurality of material segments (S 1 , S 2 , ..., S n ) , each of said plurality of material segments including a first aperture and a second aperture formed through said sheet of material; a cylindrical forming tube sized for drawing a left edge (E L ) and a right edge (E R ) of said elongated sheet of material (S) together in an overlapping configuration to form said elongated sheet of material (S) into a tube shape; a sealer sized for sealing said left edge (E L ) and said right edge (E R ) of said elongated sheet of material (S) to one another to form said tube shape; a gusseting mechanism sized for forming a gusseted tuck in each of a left sidewall panel portion (SP L ) and a right sidewall panel portion (SP R ) of said tube shape to form a gusseted tube shape; and a sealing mechanism that folds and seals said first segment (S 1 ) of said plurality of material segments at said first aperture and at said second aperture to provide an end wall (EW) of said first segment (S 1 ) with a flat, rectangular-shaped footprint; and a cutter operable to sever said first segment (S 1 ) from a second segment (S 2 ) located downstream from said first segment (S1), wherein said cutter and said sealing mechanism form a "K" shape integrated machine, and wherein said cutter and said sealing mechanism cooperate to provide a sealed edge at said end wall (EW) that has a substantially "U" shape and that has pair of legs extending from a cross member that joins said pair of legs , wherein said legs extend from said cross member at an obtuse angle and away from one another. a support rod or a spindle that rotatably supports an elongated sheet of material (S) defined by a plurality of material segments (S 1 , S 2 , ..., S n ) , each of said plurality of material segments including a first aperture and a second aperture formed through said sheet of material; a cylindrical forming tube sized for drawing a left edge (E L ) and a right edge (E R ) of said elongated sheet of material (S) together in an overlapping configuration to form said elongated sheet of material (S) into a tube shape; a sealer sized for sealing said left edge (E L ) and said right edge (E R ) of said elongated sheet of material (S) to one another to form said tube shape; a gusseting mechanism sized for forming a gusseted tuck in each of a left sidewall panel portion (SP L ) and a right sidewall panel portion (SP R ) of said tube shape to form a gusseted tube shape; and a sealing mechanism that folds and seals said first segment (S 1 ) of said plurality of material segments at said first aperture and at said second aperture to provide an end wall (EW) of said first segment (S 1 ) with a flat, rectangular-shaped footprint; and a cutter operable to sever said first segment (S 1 ) from a second segment (S 2 ) located downstream from said first segment (S1), wherein said cutter and said sealing mechanism form a "K" shape integrated machine, and wherein said cutter and said sealing mechanism cooperate to provide a sealed edge at said end wall (EW) that has a substantially "U" shape and that has pair of legs extending from a cross member that joins said pair of legs , wherein said legs extend from said cross member at an obtuse angle and away from one another. <EOS>
