Conventional Paper Trim Handling Systems vs the BERVAC ...

A pulper exhaust system is not required. Dimensioning and detailing of a BERVAC system requires a thorough study of the winder, and minor changes are occasionally required at the machine in order to obtain a smooth removal of trims. These changes often make it possible to increase the maximum trim width up to 250 mm.

Procedure for boosting the ventilation in the hood of a ...

Aug 27, 1985· Endeavours have all the time been directed to increasing the humidity of the exhaust air from the paper machine hood. In the case of open hoods, the humidity of the exhaust air was 50-80 g per kg of dry air. With closed hoods the value of 100 g per kg of dry air was reached in the 1960's, and this was brought up to 120 g per kg of dry air in ...
