  • Manufacture of metal strip
    Patent number: 4070739
    Abstract: Metal strip is peeled from a rotating cylindrical workpiece whose longitudinal axis is greater than the desired strip width by feeding a first cutting tool into the peripheral surface of the workpiece as it rotates so as to form a groove in the surface which is spaced through one end of the workpiece by a distance equal to the desired strip width, feeding a second cutting tool continuously into the peripheral surface of the workpiece to produce a continuous metal strip of width equal to the distance between the workpiece end and the groove and collecting the peeled strip by winding it around a coiler.
