Abstract
An improved method of manufacturing a flexible container is disclosed in which there is woven in selected areas of a length of fabric formed by a body of warp and weft yam threads where yarns in the weft are controlled in the intended load and pressure-bearing areas during weaving. Preferably, the area where tension is required of the yarns where product in the container is exerting pressure in the horizontal direction once filled being greater than the area where no or less load in the horizontal is exerted and during lifting where an area where no weft yarns are needed are reduced in weaving and therefore is greater in the tension of the body yarns in the horizontal load-bearing direction. Having increased weft yarns where a join or seam is needed. Having increased weft yarns where a lifting device or belt is attached to the fabric such needing a higher weft count for stitching or attaching and transferring load and reducing said weft where no lifting device is attached or where no tension is placed on the fabric by the join or attaching means force. Where such fabric is rotated 90 degrees and where the weft becomes the warp and the warp the weft and a lifting loop may be attached to the area of increased yarns or where a seam or join is made. A length of woven fabric being woven and cut and formed in such a manner as to reduce the amount of material used in a conventional method in production of such a flexible container bag. Summary and objective of the invention It is an object of the present invention therefore to overcome or substantially reduce these disadvantages, primarely the strengthening, increasing or reducing of the weft in the fabric where nessasary, which may be in various places and various lengths in a length of fabric used to make a flexible bulk container or any other type of bag with utility requiring such.
