Title: Continuous measurement of water retention in paper coating -  is through brilliance values of measured reflected light at coating station
Inventor: LAFAYE JEAN-FRANCIS
IPC: G01N21/35
Filed: 1991-10-09
Abstract: To give a continuous measurement of the dynamic water retention in a coated web, partic. paper after fluid coating application, a wave train (1,2,3) in a known frequency spectrum is generated at a plane in relation to the moving web (4) and at a different incidence angle from the standards to the plane defined by the web, at a gap of 0-2m from the coating station (9). The receivers (7,8) are on the same plane as the signals of the wave train reflected from the web (4). The values of the received signals are used to register the volume of the damp applied coating layer. Each measurement is repeated at an interval which is greater than the gap between the first measurement and the coating station, but less than 2-20m from the coating station, to gives values of the same level to show the changes over time to base the control for a constant web speed of travel. The mean rise in the change indicates the penetration speed of the fluid in the web and the sought-for dynamic retention of the fluid in the web. ADVANTAGE - The method gives a continuous measurement of the dynamic water retention of a fluid coating on a paper web, at the application station, and gives an analysis of the weight of the damp coating.
