successively passing through the roll openings adjusted by the displacement of
the rolls.
The roll
surface temperature is controlled by supplying steam or water. Uniform heating
is provided by steam circulation in special peripheral channels.
The
instrumentation ensures control of heating temperature, rotational speed of the
rolls and the roll opening; provision is made for audible and light warning.
The calender
is equipped with an original wedge device which makes it possible to improve
