Abstract

PURPOSE:To detect the diameter of a sheet roll without making contact with the surface of the sheet roll by emitting an ultrasonic beam nearly at a right angle to the axis of the sheet roll. CONSTITUTION:An ultrasonic beam S transmitted from a transmitting sensor 51 is set so as to be emitted nearly at a right angle to the axis C of the sheet roll 1. Thus, by setting the angle of the ultrasonic beam in this way, the ultrasonic beam S is always projected out nearly at a right angle to the outer peripheral face of the sheet roll 1, while the reflected wave W is perpendicularly reflected from the outer peripheral face of the sheet roll 1 and detected by a receiving sensor 52. An ultrasonic level meter 4 detects the diameter D of the sheet roll which is being unwound to adjust the braking torque of a powder brake 7. Thereby, the tensile force T of a sheet 2 can be adjusted to be nearly constant.
