Abstract
A sheet and web cleaner has a pair of substantially identical units in facing relation, providing a path for transporting a sheet or web therebetween. Each unit includes a suction hood with an inlet slot. A pair of channels adjacent and parallel thereto have a pressurized air ionizing bar which discharges ionized air at high velocity onto a moving sheet or web. A faceplate covers the channels and the inlet slot and has a tapered central elongate inlet opening which overlies the inlet slot. Elongate air discharge openings overly each of the channels adjacent the inlet opening. A plurality of spaced ridges are disposed on a side of the faceplate proximate the sheet or web oriented relative to a direction of travel of the sheet or web from a travel direction towards respective edges of the sheet or web. Spaces between the ridges communicate with the inlet and discharge openings.
