Test Calender (Simplified Super-calender Type)

Calendaring is performed in the finishing process of raw paper or coated paper. This process gives gloss to paper surface, improves smoothness, and adjusts sheet thickness. Various mechanical constructions and roll composition are used for specific purposes. They are classified broadly into three kinds of combination: metal and metal rolls (machine calendar), metal and elastic rolls (super calendar), and metal and resin rolls (soft or gloss calendar). It is desirable to select a test calendar most suitable for the intended purpose, considering many items including material used, paper width, linear pressure, temperature, pressurizing method, heating method, sheet paper or continuous paper.
