Abstract
A washing system for cleaning a moving web includes an array of a plurality of stationary nozzles arranged in sets controlled by a control valve and operated in groups. The array includes sufficient nozzle sets each having a spray width of from 5% to 50% of the web width, such that the combined spray width of all nozzle sets is necessary and sufficient to cover substantially the entire web width with cleaning spray. Groups of valves may be operated such that some nozzle sets are turned on while other remain off, thus conserving washing fluids. The nozzles operate at pressures of 1500 to 3500 psi, or 2000 to 3000 psi. Preferably the web is a continuous loop web.
