WEB-LIKE BODY THICKNESS MEASURING DEVICE, DISPLAY METHOD OF MEASURED VALUE OF THICKNESS, AND THICKNESS MEASURING METHOD

PROBLEM TO BE SOLVED: To provide a thickness measuring device, a display method of a measured value of thickness, and a measuring method which improve objectivity and reliability of a measured value of thickness of a web-like body.SOLUTION: In a stationary type thickness measuring device 10, thickness of a web-like body 12 is measured by abutting a contact 15 of a prescribed shape against the surface of the stationary web-like body 12 at a prescribed pressure. The position of the contact 15 is detected by a thickness sensor 11, and abutting speed of the contact 15 is detected by abutting speed detection means 28. Stabilization time after the contact 15 abuts against the surface of the web-like body 12 until the movement of the contact 15 in the thickness direction is stabilized is measured by timer means, and after the stabilization time has passed, the thickness of the web-like body 12 is detected by the thickness sensor 11. In the case of a continuous type thickness measuring device, a feeding speed of the web-like body 12 is detected by speed detection means.
