Dewatering system with adjustable width suction slot.

摘要

@ A suction dewatering system for a paper making machine has a suction device (10) with an opening (12) extending longitudinally in a direction transverse to the path (P) of material travel through the machine. Elongated wear strips (20a, 20b) are supported on opposite sides of the opening (12) to define a suction slot (22) therebetween. A guide channel (26) extends longitudinally through at least one of the wear strips (20a, 20b) in a direction parallel to the suction slot (22). An adjusting plate (38) is shiftable longitudinally within the or each guide channel (26). Oblique cam slots (40) in the or each adjusting plate (38) coact with fixed guide members (34) to laterally adjust the position of the one wear strip (20a or 20b) relative to the other wear strip (20b or 20a) thereby to vary the width of the suction slot.
