Claims

[Scope of utility model registration request]

When winding the strip onto the mandrel, a plurality of unit rolls that can be operated to press against and separate from the mandrel, a unit roll drive device that presses each unit roll onto or separates from the mandrel, and a gap between the mandrel and the unit roll. A strip tip detector detects the tip of the strip entering the mandrel, and detects the tip of the strip from the tip detection signal of the detector and the signal of the detector that detects the amount of movement of the strip attached to the pinch roll or mandrel on the mandrel. In the unit roll step avoidance device, the unit roll step avoidance device includes a calculation unit that calculates the position of the unit roll, and a controller that controls the unit roll drive device so that the unit roll avoids the step position based on a signal from the calculation unit. The detector consists of a plurality of optical fibers whose light-receiving ends are arranged across the width of the strip perpendicular to the length direction of the strip1, and the tip detection signal from the detector is detected when the strip passes under the detector. The controller includes detection signals for the first detection end and the last detection end based on the shape of the tip of the strip when the strip is rolled. A step avoidance control device for a unit roll, characterized in that the unit roll is controlled so that the unit roll avoids the step position of the strip while the detection end passes.
