When manufacturing a plurality of pieces of a strip material by cutting a belt-like member along a length direction thereof, said belt-like member having, embedded therein, a plurality of reinforcement cords arranged parallel to each other, and weft provided so as to intersect the reinforcement cords, a captured image showing an image of at least the reinforcement cords in a cross section of one end of the belt-like member in the length direction is used to detect the position of each of the reinforcement cords (RC) in the image, the number of the actual reinforcement cord (RC) to which each of the reinforcement cords (RC) in the image corresponds is determined on the basis of intervals between the detected adjacent reinforcement cords (RC) in the image and an average cord interval, and a cutting position (Xa) is set. |
