Then, when the pin comes to a bending amount measuring part, the pin is released from the pins 51, 52. The base end 12 of the pin is pressed to a V-shaped groove 43 of a rear main drum 41 by a disk 6, so that the pin is clamped. The front end part 11 is free to swing within a U-shaped groove 44 of a front main drum 42. The swinging amount, that is, bending amount is measured by a series of sensors 81-86 confronting each other to the advancing directio of the pin 1.
