PROBLEM TO BE SOLVED: To provide a lapping amount adjusting method for a shear cut-type slitter using a round blade which can automatically adjust a lapping amount, and a device. SOLUTION: Lapping amount adjustment for a shear cut-type slitter using the round blade is performed by automatically measuring a diameter of a knife changed at the time of knife replacement by using a cutting edge detection sensor and by calculating a knife position to attain the desired lapping amount on the basis of the measured knife diameter and a cutting edge detection point of the cutting edge detection sensor. In the shear cut-type slitter using the round blade, the diameter of the replaced knife can be automatically or semi-automatically measured, and load for knife replacement can be very simplified because lapping amount of upper and lower blades can be automatically adjusted. Further, the knife replacement can be easily and satisfactorily performed even by an unskilled operator. COPYRIGHT: (C)2011,JPO&INPIT
