Paper Machine Suction Couch Roll
Suction Couch Roll Description
The Suction Couch Roll dewaters the sheet as the felt belt passes through to improve the moisture uniformity of the sheet to the extent required for felt feeding. Suction Couch Rolls are usually heavily countersunk to maximize open porosity and are coated with high wear-resistant rubber or composites to minimize wear on the coating.
