Abstract (en)
The present invention relates to a method for production of bags for the transport and storage of bulk goods or liquids, wherein use is made of tubular fabric cut into several pieces, which are then assembled together, comprising the steps of: - providing a tubular fabric; - flattening said tubular fabric to form a first double-thickness fabric having two opposite sides, respectively an internal side (11 a) and an external side (11 b), extending between two flattened edges (12, 14); - folding-in or pleating at lest one of the flattened edges (12, 14) of said double-thickness fabric (10) to form a gusset (20); - cutting said tubular fabric into pieces and assembling said pieces to form a bag; wherein the assembly of two said pieces (10, 10') comprises the steps of: - connecting together the gussets (20) of two said pieces (10, 10') by means of a stitching or a welding, said stitching or welding extending along a connection line (21); - assembling the first and second pieces (10, 10') by means of seams (23) formed around or near first to fourth gusset ends (15, 19, 15', 19').
