ABSTRACT:
A separating jet blast air control assembly utilizes a regulating valve to control the amount of compressed air supplied to separating and fanning blowers of a sheet feeder. A valve disc that dumps excess compressed air is biased against a valve seat by a biasing spring. The force applied by the biasing spring is adjustable in accordance with an output from a controller in response to production speed, sheet characteristics and other variables.
