Title:
TENSION CORRECTION CONTROL DEVICE OF PAPER MACHINE WINDER FACILITY
Document Type and Number:
Japanese Patent JP2002128348
Kind Code:
A
Abstract:

To solve a problem in the paper machine winder facility, wherein a tension roller has a load cell a measured tension by the load cell for measuring the paper tension does not indicate an actual tension by adjusting a spreader bar for uniforming paper tension in the width direction to fail to brake a supply paper roll.

This tension correction control device comprises a plurality of segment rolls divided in the width direction of paper, a tension setting apparatus 11 for setting a reference tension of the paper in the paper machine winder facility having a tension roller having the tension measuring load cell in a bearing of adjacent segment rolls of the plurality of segment rolls, a correcting apparatus 14 for correcting the paper tension value measured by the load cell 13 of the tension roller at a spreader bar adjusting position, an adder-subtracter 12 for adding and subtracting a paper tension value corrected by the correcting apparatus 14 and a basic tension set by the tension setting apparatus 11, and a deviation apparatus 15 for deriving a deviation value based on the value calculated by the adder-subtracter 12. The supply paper roll is braked for tension correction based on the deviation value derived by the deviation apparatus 15.
