Abstract
A vacuum control system and method for dewatering fabrics on a papermaking machine including a suction pipe and a vacuum pump connected to the suction pipe to supply a desired vacuum level. The fabric is passed over a slot in the suction pipe so that suction applied therethrough will dewater the fabric. Controls are connected to the suction pipe and to the vacuum pump responsive to an increase in the vacuum level in the suction pipe as fabric permeability decreases to correspondingly lower the speed of the vacuum pump and retain the desired vacuum level in the suction pipe.
