Title:
シート製造装置
Document Type and Number:
Japanese Patent JP6939349
Kind Code:
B2
Abstract:
To provide a rigidity measuring device with which it is possible to detect the rigidity of a sheet material, and a sheet manufacturing device.SOLUTION: This rigidity measuring device comprises a space that tolerates the deformation of a sheet material, and a detection unit for detecting the amount of deformation of the sheet material in the space, characterized in that the rigidity of the sheet material is calculated from the detection result detected by the detection unit. The detection unit is an optical system and designed to measure the distance of a deformed part of the sheet material, detecting the amount of deformation of the sheet material that is flexurally deformed by the deadweight.SELECTED DRAWING: Figure 3
