Tissue Machine

Tissue paper is produced by feeding paper pulp into a steam-heated drying cylinder known as a Yankee dryer. This takes the pulp from about 40% dryness to around 90%. It is then crinkled, or creped, before being rolled to a final finish.

The Yankee dryer cylinder is sprayed with adhesives, which makes the paper stick. A doctor blade scrapes the dry paper off the cylinder surface, causing creping. This creping is controlled by a combination of the adhesive strength, blade geometry, speed of the Yankee, and properties of the original pulp.

Drying the paper has an impact on the web integrity and surface quality of the paper that must be monitored. In addition, the success of the creping process can be verified by an on-line, real-time inspection system that can spot defects.
