Abstract
PURPOSE: To correctly detect the amount of a loop caused in a conveyed sheet material between rollers even when the material moves in a zigzag direction, by equipping a function generator correcting a detected value of the loop amount in accordance with a detected signal of position shifting to the direction of sheet width.
CONSTITUTION: When a sheet material 1 completely covers required detection width Wo of a gap amount detector 3, the detector 3 can correctly detect a gap amount h to obtain a correct value of loop amount H from a converter 4. However, the sheet material 1 is shifted its position to the direction of sheet width not to cover the detection width Wo, if the detection width is narrowed to width W, a detecting signal of the detector 3 decreases in accordance with Wo-W. Here a detection signal characteristic is previously caught for the effective detection width W to impart a corrective function to a corrective function generator 6, if output of the converter 4 is corrected by the corrective function generator 6 in accordance with the effective detection width W of a position shifting detecting means 5, the correct loop amount H can be obtained.
