Roller Covered with Rubber for Paper Making
In the immersing-pond sizing pressing operation, the sizing pressing rolls must be used in pairs; and one hard roll and one soft roll can provide proper pressure for the highly efficient paper-sheet sizing operation and reduce loss of the paper sheets. The hard sizing pressing cladding materials must keep the stable hardness and the medium-high curve at the temperature of 110 DEG C so as to ensure uniform pressure area strength and avoid the uneven wearing of the cladding materials of the soft roll. And the hard sizing pressing cladding materials must also keep a certain surface smoothness so as to achieve the optimum paper-sheet transfer/separation effect and avoid the cracking of the rubber films.

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.
