Dewatering system with adjustable width suction slots

摘要

A suction dewatering system for a papermaking machine has a suction device with an opening extending longitudinally in a direction transverse to the path of material travel through the machine. Elongated wear strips are supported on opposite sides of the opening to define a suction slot therebetween. A guide channel extends longitudinally through at least one of the wear strips in a direction parallel to the suction slot. An adjusting plate is shiftable longitudinally within the guide channel. Oblique cam slots in the adjusting plate coact with fixed guide members to laterally adjust the position of the one wear strip relative to the other wear strip to thereby vary the width of the suction slot.
