    摘要： A bag for liquids, pastes, or granulates. The bag consists of four flexible sheets. The edges of the sheets are fastened together tight along their sides and bottom and to some extent along the top, creating a front wall (1), a rear wall (2), and two side walls (3 & 4), and the four walls demarcate the inside of the bag. The sheets the side walls are made of are thicker and/or more rigid than the sheets the front and rear walls are made of. The bag is designed such that when full it will stand balanced and stable on a level surface.

    摘要： An expandable plastic film gusseted bag is utilized. As in conventional bag manufacture, each front gusset panel is connected to a rear gusset panel and each of the gusset panels is foldable between the front panel and the rear panel to provide a continuous bag periphery. A bottom joins the bottom of the front panel, rear panel, two rear gusset panels and two front gusset panels at substantial right angles to the side edges of the front panel, rear panel and gusset panels to close the bottom of the bag and leave only the top open. The improvement provides each plastic bag with eight first linear folding axes, each configured adjacent the bottom and within one of the front panel, each front gusset panel, the rear panel and each rear gusset panel. These folding axes extend from a joinder of a gusset at the bottom to the side edges of the front panel or the rear panel and the front gusset panel or the rear gusset panel at an approximate 45.degree. angle. The folding axes are made by a process from to a group consisting of either a cold seal or a hinge in the plastic film while the film is planar. On opening of the expandable gusseted bag, the bottom seal of the bag is disposed adjacent the gussets and forms a generally triangular shaped overlay relative to the gussets to form a flat bottom bag.

    摘要： A method is disclosed of constructing a flat bottom in a plastic film tube having an open upper end, a closed lower end formed by a transverse seal, forward and rearward sides and a pair of opposing pleated sides that interconnect the forward and rearward sides. The method includes the steps of releasably engaging a lower vacuum and a lower clamp with a transverse section of the rearward side of the tube to provisionally hold the transverse section. A lateral section of the forward side is gripped and raised by an upper vacuum and an upper clamp to expose a portion of the pleated sides such that first and second pockets are formed, respectively, in the sides. The sealed lower end is drawn toward the upper end to fold the tube along first and second transverse fold lines in the forward side, along a third transverse fold line in the transverse section of the rearward side, and along fourth and fifth fold lines, respectively, in the pleated sides such that the first and second pockets are located in the pleated sides, respectively between the first and third fold lines and the lower end of the bag. Pressure is applied to the tube to form creases along the first, third, fourth and fifth fold lines, which define the perimeter of the flat bottom of the tube.

    摘要： Flattened tube sections for making sacks are continuously supplied by a main conveyor and selectively fed longitudinally to one of a plurality of connecting conveyors leading to respective production lines along which the sections are moved transversely after turning by respective turntables. The connecting conveyors for the second and subsequent production lines receive their tube sections from an intermediate conveyor. A deflector is pivotable between the intermediate conveyor and the connecting conveyor for the first production line.
