摘要：The coating (10) of the fibrous web (1) is brought into contact with an indicatorsurface (2), during or after drying and before smoothing. After the fibrous web is ledaway from it, the indicator surface is inspected for coating adhesion. The fibrous web isbrought into contact with a smooth indicator surface (2), which runs with the web. Some
of the coating is scraped off directly after application. Following coating, drying iseffected at least partially without contact. Optical inspection examines the indicatorsurface for coating adherence. To smooth the fibrous web, it is passed through
smoothing nips. These are opened when the indicator surface demonstrates adherence,or the adherence exceeds a set limit. The indicator surface is cleaned after testing. It isarranged at least 20 meters ahead of smoothing, at which location the web takes 0.5-2 sto reach the first smoothing nip. In the equipment used, contactless drying is by infra redradiation, or hot air blowing. A camera is used for optical testing. The indicator surface isdark. It is on a rotating roller, especially a guide roller (9). It is cleaned by a rotary brush.A control unit connected to the testing unit (3), operates the smoothing rollers. Anindependent claim IS INCLUDED FOR corresponding test equipment.
