摘要:
The machine for producing a corrugated board includes a first corrugating roller (3) and a second corrugating roller (5) defining a corrugating nip (7) through which a first web material (N1) passes. A gluing unit (9) applies a glue on crests of the first web material (N1) formed in the corrugating nip (7). A pressing member (11) cooperates with the second corrugating roller (5) to press a second web material (N2) against the crests of the first web material (N1). A pressure regulating system adjusts the pressure of the pressing member (11) against the second corrugating roller (5). At least a first pressure chamber (27C), which contains a pressure liquid and a pressure transducer, is associated with a first abutment (33) for said pressing member (11). A control unit (69) opens a stop valve (39) when the pressure detected by the pressure transducer (37) is outside a tolerance range.
