ABSTRACT:
Papermachine felts and wires are cleaned and maintained by pressurized fluid jets or showers which are oscillated transversely across the felt running direction over a fixed oscillation stroke distance. Superimposed on the fixed stroke distance is a periodic shift of the stroke reference point so that successive oscillations are not terminated at the same point. The oscillation drive mechanism is enclosed within a low pressure, gas-tight housing serviced by a pressure regulated gas supply. A reversible A-C motor is used to drive the mechanism.
