A fabric bulk bag and a method for constructing the same, the bag including a continuous sidewall, a top portion, and a bottom, all defining a bulk storage space therein; the bottom further comprising eight sides which define an octagonal shape having an enlarged footprint so that the bag wall is sewn to the bottom in less time than a round shaped bag, yet when filled stands more upright with less tendency to lean than the current square shaped bags thereby providing a safer more dependable stacking bulk bag. In the method of producing the fabric bulk bag, the bag is constructed in less time than the prior art round bottom bags, uses less wall fabric than prior art square bottomed bags and when constructed and filled, supports itself more stable on a floor or pallet because it provides substantially more base for the product to rest on. In other embodiments, the bag would be multi-sided with greater than four sides.

There is disclosed a bag for the transport and storage of bulk goods or liquids formed by the assembly of several double-thickness pieces of fabric, including first and second pieces of fabric, each having opposite first and second sides extending between first and second folded-in flattened edges. Each piece of fabric includes at least one gusset defined by a first oblique section extending between the first folded-in flattened edge and a first gusset end positioned on the second side of the piece of fabric and a second gusset end positioned on the first side of the piece of fabric. The first and second pieces of fabric are assembled such that the second side of the second piece of fabric is in contact with or close to the first side of the first piece of fabric such that the first and second gusset ends of the first and second pieces of fabric are substantially aligned. The first and second pieces of fabric are assembled by means of seams formed around or near the first and second gusset ends of the first and second pieces of fabric.

A material web fixing device is used as part of a filter bag manufacturing installation. A material web transport device is used to transport at least two material webs, which fixed together at a distance from one another by at least one fixing seam, along a transport direction. A plurality of sewing units each have stitch forming tools configured as a sewing needle and a looper which interact with a thread. The material webs can be passed through between said stitch forming tools in the transport direction. An excess thread production unit is used to lengthen a thread path between the material webs. The excess thread production unit is arranged between the material webs in the thread run during operation. As a result, a material web fixing device is obtained, which allows filter bags to be produced with larger bag openings, particularly with larger opening extensions between the material webs.

A fabric bulk bag and a method for constructing the same, the bag including a continuous sidewall, a top portion, and a bottom, all defining a bulk storage space therein; the bottom further comprising eight sides which define an octagonal shape having an enlarged footprint so that the bag wall is sewn to the bottom in less time than a round shaped bag, yet when filled stands more upright with less tendency to lean than the current square shaped bags thereby providing a safer more dependable stacking bulk bag. In the method of producing the fabric bulk bag, the bag is constructed in less time than the prior art round bottom bags, uses less wall fabric than prior art square bottomed bags and when constructed and filled, supports itself more stable on a floor or pallet because it provides substantially more base for the product to rest on. In other embodiments, the bag would be multi-sided with greater than four sides.
