<p>Automated machine for the continuous bias cutting of an elongated tube of material, such a tubular knitted fabric, into a plurality of individual strips, and winding the strips into a plurality of rolls of fabric. The machine comprises a supply section, a spreading and tensioning section and a cutting and rolling section. The tubular material or fabric is stored in the supply section in a rotatable receptacle in the form of a stack of untensioned superimposed flattened folds. The tube is advanced axially from the supply to the cutting and rolling section of the machine by a plurality of skewed rotatable cylinders. As the flattened tube is withdrawn from the supply, it passes over a spreader which opens and tensions it. The rotatable skewed cylinders cause the advancing tube to rotate about its axis as it advances to be cut into strips. Selectively operable control means are utilized for rotating the supply receptacle, to correlate its speed of rotation with the speed of rotation of the tube of material, to maintain the tube substantially untwisted, relative to its axis, and under substantially uniform tension, as it advances to the cutting and rolling section of the machine.</p> |
