  • Patent number: 4131979
    Abstract: Automated machine for the continuous bias cutting of an elongated tube of material, such as tubular knitted fabric, into a plurality of individual strips, and winding the strips into a plurality of rolls. The tubular material is advanced axially at a uniform rate from a supply to a cutting and rolling section by a plurality of skewable rotatable cylinders acting as a positive feeding means. As the tubular material is withdrawn from the supply, it passes over a spreader which opens and tensions it. The skewed cylinders cause the tube to rotate about its axis as it advances. Control means are utilized to adjust automatically the skew angles of the cylinders, to increase or decrease the rate of advance of the tube, to compensate for variations inherent in the material which affect its rate of feed. Control means also are utilized to adjust automatically the tension exerted by the spreader, to correlate such tension with the rate of advance as determined by the skew angles of the cylinders.
