Abstract
The dry-creping process is dependent on a balanced adhesion of the paper web to the MG-cylinder at the moment of removal of the web by the doctor blade. The adhesion of the web usually is on a layer of organic origin attached to the metal surface. The physical appearance of the intermediate layer has been studied on production machines and on various model surfaces and its chemical composition analysed. Laboratory techniques have been developed for studies of the peeling of fibrous webs from metal surfaces. Variables associated with the building-up of the intermediate layer and their effect on the peeling resistance have been investigated. Different pulps show widely different adhesion and react to different degrees to drying variables.
