TENSION ADJUSTMENT DEVICE FOR MULTI-ROW METAL PLATE AND METAL PLATE TENSION ADJUSTMENT METHOD THEREBY, AND METHOD OF TAKING UP MULTI-ROW METAL PLATE

摘要

To increase a take-up speed on the demand that winding-up force when a coil is taken up is in a uniform form, namely, respective metal plates of a multi-row metal plate can be adjusted more speedily and strictly into a uniform form so as to improve an operation rate of multi-row metal plate taking-up, and thus productivity is improved.SOLUTION: Since a quantity of clamping by a deflector roll is adjusted, tension of all metal plates of multiple rows is adjusted, and since each metal plate is provided with a plurality of grooves at an elastic material lining made of an elastic material having lower hardness than a tension adjusting roller, the tension of the multi-row metal plate is adjusted. The whole integral adjustment and the individual adjustments are combined so as to adjust the multi-row metal plate tension into a uniform shape.SELECTED DRAWING: Figure 1
