Abstract (en)
[origin: EP0317528A1] This invention concerns a mechanical device for installation on automatic sewing machines, for repeatedly inverting the position, while leaving the direction unchanged, of a pair of needles fitted side by side, co-operating with a single "crochet" and capable of carrying out special, particularly decorative, sewing stitches, which are often used in the footwear sector and more generally in the leather industry.
