CALENDAR ASSY

Calendars are used to modify the surface attributes of uncoated or coated paper, as well as to produce paper with a specific density. The paper industry makes a distinction between a number of calendars, including two-roller calendars, multi-roller calendars, super-calendars for glazing, and highly heated multinip calendar systems, which operate both independently of and in conjunction with paper machines’ calendars (offline and online). Changes in paper quality necessitate ongoing adjustments to calendaring procedures. In many situations, existing systems can be modified with the requisite skills and finely tuned to the new tasks before expensive new installations are required.

The final phase in the production of paper that affects the characteristics of the paper and the board is calendaring. The most crucial surface qualities, smoothness and gloss, are improved by compression of the paper surface and its construction. Before coating or size press, calendars are also used as pre-calendars. Calendaring is mostly used to enhance the paper’s surface characteristics and manage the calliper profile.

All grades of paper and board can be calendared, according to Supreme Technologies. The pace and deckle of the calendar paper machine operation, as well as the quality of the paper or board, influence the sort of calendaring approach that is used. Choosing the appropriate concept for each application is crucial.

The Soft Nip Calendar method makes use of rolls with a soft, elastic cover that creates a nip that mimics the surface of the tempered roll with a hard surface, so improving the qualities of the paper. The end typically improves the web’s printability and performance aspects.
