Heating zone

Before the glass sandwich reaches the pre-heating zone, its thickness and width
are measured and sent to the control system. The calculated values for the subsequent
transport allow an automatic passage through the heating zones at speeds between
0,2 and 8,0 m/min. At the same time,  thyristors regulate the infrared radiators, so that the
rays will be perfectly absorbed by the film. Temperature detectors control the air heater
which serves to warm up the glass.

Presses I and II now automatically adjust the vertical clearance to the thickness of the
package and establish the distribution of compression of the upper press calendars.
Well-balanced heating and regular air evacuation are thus guaranteed for each package.
