Abstract

In vacuum corrugation feeders as disclosed in U.S. Patent 4,324,395, a need has been shown to reduce air knife flow for more rapid sheet acquisition. This is especially desirable when acquisition times are long (> 200ms) or when system timing would prefer a short acquisition time as in high performance recirculating document handlers. Long acquisition times occur mainly when the sheet stack is "high" with respect to the vacuum plenum ports, and the stack is "stiff" i.e., curl up, high stack, heavy weight paper.
