Abstract
PURPOSE: To compensate a diameter of a roll in high accuracy by comparatively simple constitution, by using a pulse transmitter, a pulse frequency divider and a set instrument.
CONSTITUTION: A pulse frequency divider 7 and a roll diameter set instrument 8 are insertion mounted between a pulse transmitter 4 and a counter circuit 5. With a transmission 3 and the pulse transmitter 4, a velocity ratio and pulse frequency per one revolution are beforehand decided so that fixed measuring accuracy can be obtained to the diameters of imaginary rolls that are larger than a diameter of a roll of an actual measuring roll 2 and become to 10n. The pulse frequency divider 7 pulse frequency divides in proportional to the set value of the roll diameter set instrument 8, and the counter circuit 5 can continually count the right quantity of materials moving.
