Product Description

Paper Machine Spare Parts Steel Vacuum Couch Roll  

Product Description

The vacuum couch roll is located at the end of the wire section of the paper machine. Its structure is basically the same as that of the suction roll. It is composed of a roll body, a vacuum box, a bearing seat on the operating side and the transmission side, a water spray tube, an air cushion tube, a rubber wheel, and a vacuum regulating valve. The roller shell is made of bronze or stainless steel, and the thickness of the roller shell is determined by the required rigidity and strength.
