Abstract
A web treatment device is disclosed capable of heating and creping a fibrous web with control systems for uniform operation. The web is pressed between two belts in a compression zone, where is it also subject to a temperature gradient that can assist in water removal. Durable coatings on the press belts can assist in maintaining good performance. The system can be used to apply texture to a fibrous web or drive chemical reactions or other physical changes in the web.
