Abstract

PURPOSE: To enhance the measuring accuracy of a cable, by calculating the length and the surface unevenness quantity of the cable.
CONSTITUTION: A length measuring roller 16 is rotated by the movement of a cable 20 because of its close contact with the cable 20 and moves up and down so as to follow the surface unevenness of the cable 20. The rotation of the roller 16 is transmitted to a pulse generator 50 through a shaft 46 and a coupling 48 and the pulse generator 50 generates a pulse at every predetermined angle of rotation of the roller 16 to input the pulse to a measuring instrument 38. By this method, the surface length of the cable 20 is detected by the roller 16 and the unevenness quantity of the cable 20 is detected as the change quantity of the roller 16. Then, trigonometry, especially, the Pytagorean theorem is used at every predetermined surface length of the cable 20 to calculate the length of the axial line of the cable 20 and the calculated length is successively integrated to measure the total length of the cable 20.
