Abstract

PROBLEM TO BE SOLVED: To obtain a charging method in which the number of virtual foreign matter to be charged is confirmed and in which their arrangement operation is performed easily without being affected by the movement speed of a pass line by a method wherein an object in an arbitrary shape is formed on a roll which is detachable to a roll on the pass line and the object is brought into contact with the roll on the pass line so as to be stuck to a take-up material. SOLUTION: Virtual foreign matter 32 which is formed on a foreign-body formation roll 31 is imaged by an imaging device 41 for confirmation, image information is stored in an image memory 42, and the image information is displayed on a display device 43. Then, a visual inspection device 62 is operated, the roll 31 is brought into contact with a roll 12 in a take-up device 61, and the virtual foreign matter 32 is stuck to a take-up material 11. An encoder counter 34 sends a signal to an inspection processing part 23 when a pulse counted value corresponding to a distance at which the virtual foreign matter 32 reaches visual fields of imaging devices 211 to 214 from the point of time agree with a counted value by rotation information on an encoder 33. In the inspection processing part 23, the image of the virtual foreign matter 32 after the operation of the visual inspection device 62 is compared with an image before the virtual foreign matter 32 is charged, and the virtual foreign matter is inspected.
