Description
Coated paperboard is calendared in the finishing process after coating. For paperboard thicker than ordinary paper, it is necessary to provide the desired smoothness and gloss while maintaining its bulk. The gloss calendar is used to achieve this target, composed of steel roll and rubber roll, thereby ensuring specified quality including white gloss of the coated surface and printability. This simplified machine has been developed by improving the heat calendar. It has a roll configuration (steel and rubber) like the practical calendar, giving heat and pressure to the specimen, thereby offering desired gloss.
