Dewatering Paper Couch Roll In the cylinder paper-making machine, the dewatering couch roll operates relative to dewatering cylinder mould positioned behind the forming cylinder to form a low-pressure area, so the paper sheets are dewatered before being transferred to the suction cylinder or first pressing part. The cladding materials are high-wearing resistance rubber or polyurethane materials with medium softness (90 to 150P&J), so that the dewatering couch roll is characterized by high toughness, high anti-chemical corrosion and relatively long use period.

1) The roller is made of cast iron or seamless steel pope and the surface is coved by rubber;
2) Roller in side and outside surface will be processed;
3) We will process roller’s dynamic balance to improve machines’ stability;
4) Before the spindle head has been installed. We will make the second dynamic balance.
5) Before the spindle head has been installed. We will make the second dynamic balance.
6) Normally it is wooden case packages. Some larger rollers are used metal packaging.
