CALENDER

摘要

The invention provides a calender for in-line use in a paper machine. The calender comprises two pairs of deflection rolls controllable by zone, forming closely following roll gaps. One roll of each pair is provided with an elastic covering having a hardness of at least 85.degree.Shore D, while the other roll of each pair is a hard roll. This allows in-line calender operation at higher speeds than with known calenders.
