Abstract

A pulsed spray dampener system wherein, during low press speeds, nozzles are controlled to release pulses of dampening fluid having a fixed pulse width and fluid output is adjusted by varying the interval between dampener pulses. During high speed operation, the interval between pulses is fixed and pulse width is varied. Furthermore, the outermost nozzles of a spray bar are operated by dedicated control channels to permit better spray patterns.
