Title:
ABSORBED-WATER-DEPENDENT-FRICTION MEASUREMENT DEVICE AND ABSORBED-WATER-DEPENDENT-FRICTION MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2017/221345
Kind Code:
A1
Abstract:
This absorbed-water-dependent-friction measurement device (1) is provided with: a scale support part (2); a scale (3) supported above the scale support part (2); a measurement tool (4) that is suspended from a weighing tray support part of the scale (3) and holds a flexible, water-absorbing, sheet-like sample (9) in a space formed by the scale support part (2) such that the sample (9) is spread out and suspended; and a friction element (5) that has a portion of a spheroidal surface that is a surface of rotation around the central axis of the friction element (5), is supported such that the central axis is horizontal and parallel to the sheet surface of the sample (9) held by the measurement tool (4), is capable of translation, in a direction within a surface orthogonal to the central axis that intersects with the sheet surface, between a first position in which the friction element (5) is not in contact with the sample (9) and a second position in which the spheroidal surface is in contact with the sheet surface of the sample (9), and is such that the part of the spheroidal surface in contact with the sample (9) is capable of rotating around the central axis in the direction of gravity at the second position. The scale (3) outputs an indication value for when the friction element (5) is at the first position and an indication value for when the friction element (5) is rotating at the second position.
