ABSTRACT:
A state of an operation of cutting a rubber sheet having a number of parallel cords embedded therein by moving a cutter in a cutting direction which is in parallel with a direction in which the cords extend is detected by monitoring a first displacement of the cutter in a direction of a thickness of the rubber sheet and a second displacement of the cutter in direction perpendicular to the cutting direction. When the first displacement of the cutter exceeds a predetermined threshold value, there is produced a comparison signal having a predetermined time period. In response to the comparison signal, the second displacement of the cutter is compared with a second threshold value within the time period of the comparison signal, and when the second displacement of the cutter exceeds the second threshold value, there is produced an alarm signal which represents that the cutting operation is not carried out correctly.
