As the finishing equipment of paper machine and coater, soft roll calender has been developed rapidly because of its superior performance, easy operation, less broken ends of paper web calendering, improvement of paper quality after calendering and high operation rate of equipment.
The soft roll calender is composed of a cold cast iron roll which can be heated and regulated and a soft roll which can control the middle and high outer coating of elastic materials. Compared with ordinary paper machine calender, it has the characteristics of increasing smoothness, reducing bulk thickness loss and maintaining paper strength.
Because of the springback of the soft roll surface material, the roll surface can adapt to any bad evenness and quantitative change of the paper web, so it can have more uniform smoothness and uniform tightness than the conventional hard calender.
Another advantage of soft calendering is that the web can run under the condition of high moisture on the premise that the problems of black pressing and stain are basically eliminated. This is not only conducive to the calendering and finishing of the web, but also keeps the moisture content of the paper roll higher.
