Calender section of a paper machine

The calender part of the paper machine consists of a calender and other equipment. The paper runs between the plates to further smooth, which also makes it more even thickness. The pressure applied to the web by the rollers determines the finish of the paper and the paper has three types of finish.

The first is the Calender machine finish, or MF paper, which can be made from rough / mute (matte), looks smooth and high quality finish.

The second is called Super Finishing or MG Paper (Machine Glaze), which is glossy / glazed and suitable for highly fine halftone printing.

The third type of finishes are called plating, and the first two types of finishes are achieved by the calender itself, by placing the cut paper between the stacked zinc or copper plates and then placing them in pressure and heating under. A special surface treatment of linen finish can be achieved by placing a linen between the plates and the paper, or an embossed roll can also be used.

After calendering, the water content of the web is about 6% (depending on the ingredients). Which is wound on a roll called a roller and stored for final cutting and transport.
