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.
