What is Couch Roll
The couch roll is located in the wire section immediately after the suction box and is the roll closest to the dry section in the wire section.
Function
1) Accept the paper sheets from the suction box, and then dehydrate them to improve the dryness of the wet paper delivered to the press section;
2) Bear all or part of the load driving the papermaking wire;
3) is the starting point for the wet paper to transfer the paper sheet to the press section.
Type
There are two types of couch rolls: vacuum couch roll and ordinary couch roll. The ordinary couch roll is composed of upper and lower rolls, and the lower roll is a rotating roll. The wire surface is first squeezed and dehydrated by the upper roll, and then enters between the upper and lower couch rolls with the highest pressure. There are round holes on the surface of the vacuum couch roll, and a vacuum chamber (single-chamber or double-chamber) is arranged in the roller, and a vacuum is generated by a vacuum pump for dehydration.
