US Classification:

162209
Abstract:

The wet end of a fourdrinier paper machine includes a transversely disposed roll beneath the wire. The roll is shaped and mounted for rotation at a speed which is different from the speed of the wire to create pulses of negative pressure beneath the wire for drawing liquid from the web of fibers formed thereon. Also disclosed is a fin apparatus transversely disposed beneath the wire to create a wave of positive pressure thereunder to urge the formed web off of the wire.
