摘要:
A stitchless highly oriented polypropylene fabric bulk bag of the type that can hold 500 to 5000 pounds (226.7 to 2268 kilograms) of bulk material includes a highly oriented polypropylene fabric top, body and bottom, with a heat fused joint providing an air tight connection between the top and body, and another air tight heat fused joint connecting the body and bottom. A fill spout and discharge tube may also be provided with an air tight heat fused joint connecting the fill spout to the top and another air tight heat fused joint connecting the discharge spout to the bottom. Heat sealing machinery include heat seal bar assemblies that can self-align during heat-sealing to apply even pressure to all areas being heat sealed. A heating element is of single piece construction and can include end coupler portions as part of the single piece construction. Carrier plates used in a heat-sealing assembly line guide parts placement, provide quality checks for parts placement, and tooling set-up for machinery.

摘要:
A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

摘要:
A lifting assembly and method for a flexible bag includes one or more lift members, wherein each lift member is coupled to a layer of material, e.g., a fabric layer. The fabric layer can be coupled to a flexible bag wherein the fabric layer is an intermediate layer between the lift member and the flexible bag. The fabric layer can be heat fused or otherwise coupled to a bag without stitching or sewing, which eliminates the creation of sew or stitch holes that breach a containment area of the bag and which can weaken the bag fabric. The one or more lift members, however, can be sewn or stitched to one or more intermediate layers.

摘要:
A system and method for constructing any desired length of height linear cellular chain for use as a protective wall system, including a chain of fabric bulk bags, each having an open upper end, and interconnected along their sidewalls to define the cellular chain; and a fabric channel formed on the upper ends of each of the adjoining bags sidewalls for engaging a bag support and filling system, which includes a first metal frame member having a pair of arm members for threading through two adjacent fabric channels; the frame supported by a base member resting on the ground; a second metal frame member for receiving the distal ends of each of the arm members of the first metal frame member, at a level so that the bulk bag is supported by the arm members; bulk material to be poured into the supported bulk bag, to a level that the bag is substantially filled and no longer requires the support of the frame, so that the frame can be removed and positioned onto the next pair of fabric channels to fill the next empty bag.
