Abstract
PURPOSE: To improve the precision of cutting work, with an error correction operated, by means of detecting the both end cut parts of a material after the cutting process in a manner of non-contact further in a high precision, and performing a feed-back operation of the above detecting quantity to the cut length control system.
CONSTITUTION: The traveling speed of a cut material 1 is contactlessly detected by a cutting position traveling speed detector 6, and the blade point speed of a cutlery 3 is contactlessly detected by a blade point displacement detector 5. A detected signal is inputted to a drive controller 8, with a material 1 cut into a determined cut length of l0 and a constant sized material 2 obtained. For the material 2, the deviation value Δl between predetermined cut length l0 and actual cut length l1 is obtained in a cut length correcting device 4, and made an operation of feed-back to the controller 8, with a servo motor M controlled so as to be Δl=0.
