Abstract

PURPOSE:To accurately measure the finishing end of a rolled stock and to perform the efficient deceleration control even if a braking device is not installed by installing a wound weight computing element and a residual length detector outputting a deceleration command when a residual length reaches a set min. residual length. CONSTITUTION:A coil periphery measuring instrument 5 calculates an average sheet thickness of a product G based on outputs from a pulse generator 4, a 2nd generator 8 by use of the number of windings, a wound coil diameter of a winder 7, and outputs the number of windings and the average sheet thickness. A residual length detector 6 calculates a residual length lR by the equation based on calculated outputs of a wound weight computing element 9 by use of a sheet width value set in a sheet width setter 10, a weight value stored in a rewinding side coil weight memory 11, and a sheet thickness value set in a sheet thickness setter 13, and a previously set specific gravity value and outputs a deceleration command S if the residual length lR agrees with a previously set target value.
