Abstract (en)
[origin: WO9509943A1] The aim of the invention is to provide a method of hemming a continuous strip of textile fabric which is conveyed by an edge-folding device and whose hem is subsequently sewn to give an accurate hem even if the zone used to form the hem is distorted with respect to the rest of the strip of fabric. To achieve this, the invention proposes that the strip of fabric is conveyed through the edge-folding device to the sewing device at constant speed and the edge used to form the hem is conveyed by the edge-folding device at a speed which is different from that of the rest of the strip as it enters the edge-folding device, at the same speed as it passes through the edge-folding device and at a different speed again towards the end of its passage through the edge-folding device, the speed of the edge relative to that of the rest of the strip being controlled in such a way that any differences in width between the edge zone and the rest of the strip at the entry into and exit from the edge-folding device are compensated for.
