ABSTRACT:
A method and apparatus for longitudinally slitting metal strip under tension is provided. The method includes driving the strip forward and controlling the speed thereof through frictional engagement with the strip and slitting the strip under tension while further driving the strip, winding coils of slit strip while still further driving the strip and measuring the speed of the strip before slitting, the speed of slitting and the speed of winding the coils of slit strip and controlling those speeds as a function of the driving speed for providing a predetermined tension during slitting and for winding tighter coils of metal strip. An apparatus is also provided which includes a driven roll means before the slitter, a slitting means which is driven and a take-up winder means which is driven, as well as speed controls for slitting the strip under tension in order to provide tightly wound coils of slit metal strip ranging from light to heavy gauge.
