Abstract (en)
[origin: EP0933461A2] A sewing machine (1) attachment (4), for cutting fabric, has a cutting tool with a blade (5) rotating on an axis on the cutting plane, and at least one cutting edge (7) which projects beyond the circumference of the circular blade. The blade rotates at a speed which is indirectly proportional to the number of cutters at the speed of fabric movement. The rotating cutting blade (5) of the cutting attachment, has at least two cutting edges (7), equidistant around the rotating blade axis. The rotating blade (5) has a quadratic plan shape, with four cutting edges (7) along the sides of the quadrilateral.
