You can test both the super calendar and the soft calendar with this one device.
The super calendar can be set up with a metal roll, and by changing to a cotton roll or soft roll for the soft calendar, it allows for testing in a dual role.
Inquire About This Product
basic information
The final process in paper manufacturing is called calendaring. In this process, calendaring (applying pressure to press) is performed on the surface of the paper, which retains a few percent of moisture from the previous process. This enhances the gloss and smoothness of the paper, improving its quality. Therefore, this device is a testing apparatus that can simulate the final stage of paper production.

Applications/Examples of results
Super calendars produce higher paper gloss and smoothness with higher nip pressure. For regular printing paper and art paper, a nip pressure of about 10 nip is applied. During this process, the thickness of the paper decreases. If you want to minimize the thickness of the paper as much as possible, a soft calendar is used. A soft calendar raises the roller temperature instead of reducing the nip pressure. This allows the nip pressure to be reduced to one-fifth, thereby minimizing changes in paper thickness.
