BAG OF TEXTILE MATERIAL PROVIDED WITH PIPINGS AND METHOD AND MACHINE FOR ITS MANUFACTURING

摘要

The invention is related to a bag of textile material provided with pipings, and a method and machine for its manufacturing. The bag is manufactured from a pair of fabric sheets (1, 2), which have been cut off from a pair of web shaped materials (1', 2'). The latter have been sewn together along one of their longitudinal sides. The seam (12) has been performed such that seamless sections of a certain length (L) are formed in the corners of the bag. A first piping segment (5) is sewn in place by the seam (12) and extends beyond the ends of the seam (12) all the way out to the cross edge (18) of fabric sheets. A second piping segment (22) is inserted in-between the fabric sheets along the sides which are perpendicular to the first side, whic second piping segment is arranged to overlap the first piping segment in the area of the corners. Second seams (24) fix the second piping segments and are sewn in place overlappingly with the first piping segment.
