DEVICE FOR MEASURING THICKNESS OF CLOTH AND METHOD FOR MEASURING THICKNESS OF CLOTH

Document Type and Number:

WIPO Patent Application WO/2010/125683

Kind Code:

A1

Abstract:

Provided is a device and a method for measuring the thickness of cloth, wherein the thickness of cloth can be measured easily, quickly and accurately at a moment when a predetermined pressure is applied. A device for measuring the thickness of cloth comprises a fixed portion (20) having a base surface (21), a movable portion (30) having a pressing end (31) for pressing cloth (1) against the base surface (21), a movable portion driving mechanism (40) for moving the movable portion (30) linearly without rotation, up to a position where the pressing end (31) presses the cloth (1) against the base surface (21) from an initial position with a pressure exceeding a preset pressure, a load cell (22) for detecting a pressure with which the pressing end (31) presses the cloth (1) against the base surface (21), a pulse coder (34) for detecting the interval between the base surface (21) and the pressing end (31), i.e., the thickness of cloth, at a moment when the detection value obtained by the load cell (22) while the movable portion (30) is moving from the initial position to an overpressed position reaches the preset pressure, based on the displacement of the movable portion (30), and a control section (52).
