Rubber covered vacuum reverse roll in the paper making machine
The reverse roller is mainly used to transfer the endless felt to the paper making process through the transfer of the roller. It is an indispensable part of the papermaking machinery. Common rubber roller return rollers and vacuum return rollers are commonly used.
Due to its unique internal structure, the vacuum return roller can achieve a greater degree of dewatering of the wet paper sheet.
It consists of a roller body, a vacuum box, a water spray pipe, an adjusting screw, a pressure, and a vacuum indicating instrument.
