Rubber covered vacuum touch roll in the crescent tissue paper machine
The touch roller is the main part of the dryer section of the paper machine and is usually located below the dryer cylinder. For dewatering of paper and paper
General touch roll include rubber-coated flat rolls, grooved rolls, and vacuum roll.
Vacuum rollers are mainly used in high-speed toilet paper machines. Due to the low weight of toilet paper, the rollers need to have strong dewatering capacity at high vehicle speeds. The vacuum rollers satisfies this requirement very well.
