When the leading edge portion s of the hung-down waste paper 8 passes a predetermined position A where the detection sensor 4 is located, the detection sensor 4 is turned off.
The output state of N changes to the output state of OFF. The number of pulses output from the measuring device (rotary encoder) 3 is N during the distance Nmm in which the leading end s of the damaged paper 8 has risen from the start of rotation of the paper roll 1 to the OFF output of the detection sensor 4. ..

Half the circumference of the paper roll is hung as a waste paper 8 and then the paper roll 1
Is rotated in the direction of the arrow in FIG.
Measure mm. Then, by calculating [180 / (C + N)], the winding paper rotation angle per pulse is calculated. FIG. 5 shows a process of feeding out the broke and winding it down. In this case, the broke amount feeding amount = per one rotation of the winding paper (360 °) + L 1 , so the number of pulses = [C + N]
