Abstract: An inner bag for a transport tank is constituted of a doubled tubular film in which a tubular film is inserted into another one. An inner bag supply-discharge opening is thermally welded to an attachment hole formed in the doubled tubular film. When thermally welding one end of the doubled tubular film, a reinforcing film is put on a two-layered portion constituted only of an outer tubular film, so that the two-layered portion has the same thickness as a four-layered portion constituted of the outer and inner tubular films. Thereby, the whole thermal welding line has approximately uniform thickness such that the thinner portion dose not exist. This will prevent the deterioration in sealing property, strength and durability of the thermal welding line caused by rubbing of the thinner portion during transporting and or the application of welding energy to the thinner portion.

Abstract: An improved flexible pouch, apparatus and methodology for a pouch having an upper edge, a lower edge, and side edges extending therebetween. The side seal is 4-6±1 mm wide. The apparatus and method includes the steps of unrolling the material along a horizontal orientation, and turning the sheet of material to have a vertical orientation. The method also checks the alignment of the sheet of material, and adjusts the alignment relative to a vertical axis, to align the outer edges of the sheet of material. The method cuts the roll width of material into sections, and positions the aligned sections together to form the body of the pouch. The method forms side seams by sealing along the side edges of each pouch. The method also separates the individual pouches from the roll width of material, and removes the pouches from the machine.

Abstract: A soft shell, flexible storage tank is provided, including corners of an improved configuration adapted to resist leaks. The walls of the tank and the corners are relatively more rounded and larger in radius than those of conventional flexible tanks. The walls and the improved corners act together to resist leaks. The rounded corners tend to reduce the effective pressure in the tank walls by loading the seams predominantly in shearing stress when the tank is filled with a liquid. The rounded corners are developed as panels, which are thermally bonded to produce secure and reliable liquid-tight seams. Each of the panels is bonded by lapped seams to others of the panels. Each of the rounded corners includes a generally triangular corner that is bonded to at least three other panels. In effect, the flexible storage tank functions as a pressure vessel, which tends to resist leakage.

Abstract: An airbag and a method for making an airbag of the type that includes an irregularly-shaped panel, such as the side panels of a passenger airbag.

The straight line drawn to define the largest polygon that can be defined by any single straight line without coming too close to the inflation module hole. By segmenting the larger, irregularly shaped panel into two smaller ones with one of those being polygonal, better nesting of the segments can be obtained, which significantly improves fabric utilization to offset the labor cost from sewing the two segments together when making the irregularly shaped side panel required for the airbag.

Abstract: A pouch for sterilized materials is formed from two webs positioned face-to-face attached around portions of their edges by heat fusion, thereby forming a pouch having an interior cavity and a mouth being an unsealed portion of the webs along a top edge. An interior boundary line along the inside of the seal area has a wavy configuration which includes a series of inward-facing peaks and valleys.
