  • Patent number: 4213231
    Abstract: Metal strip is peeled from the periphery of a rotating cylindrical workpiece by feeding a cutting tool continuously into the workpiece periphery and is collected by winding the peeled strip around a rotating coiler. The rotational speed of either the workpiece or the coiler is controlled to maintain its peripheral speed substantially constant at the angular velocity of, respectively, the coiler or the workpiece is controlled in accordance with a time-dependent derived relationship to maintain a set ratio between the peripheral speeds of the workpiece and the coiler.
    Type: Grant
    Filed: July 14, 1978
    Date of Patent: July 22, 1980
    Assignee: British Steel Corporation
    Inventors: Andrew Middlemiss, Dalip T. Malkani
  • Patent number: 4085496
    Abstract: A method of manufacturing metallic strip which differs in composition across its width includes feeding a cutting tool continuously into the peripheral surface of a rotating workpiece comprising a plurality of cylindrical components of differing composition to produce a continuous strip peeled from the surface of the workpiece, and collecting the peeled strip by winding it under tension around a coiler.

  • Patent number: 4075747
    Abstract: Metal strip is produced by feeding a cutting tool continuously into the peripheral surface of a rotating cylindrical metal workpiece and coiling the peeled strip continuously around a coiler drum. The strip is initially coiled by means of a clamp connected by a flexible linkage to the coiler drum which grips the leading edge of the strip to pull it around the periphery of the drum.

  • 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.
