Abstract

PURPOSE: To prevent occurrence of surface of flaw due to slippage of steel strip on rolls, by controlling the rotational speed of un-coiling reel to raise or lower the same when ratio of difference between circumferential speed of bridle roll and moving speed of strip to the circumferential speed of the bridle roll exceeds a certain value.
