CS247130B1 - Apparatus for automatically determining the structural nephomomogenicity of fibrous materials on a paper machine - Google Patents

Abstract

The device for automatic determination of structural inhomogeneity of fibrous materials on a paper machine is used in the production of paper and cellulose. The device includes a measuring block, a light source, a light sensor and a means for renumbering the measuring block along the guide surface, connected to the control block and placed above the transport means of fibrous material. To increase the accuracy of the measurement, the measuring block has a polarizing prism placed with the possibility of rotation around the optical axis of the light source, the light source being in the form of an optical quantum generator.
