Abstract
A diverter and on-edge stacker for diverting and on-edge stacking of envelopes comprises: an envelope conveying path; a device for selectively diverting a conveyed envelope by intercepting a lateral portion of the leading envelope edge and thereby skewing the envelope; a stepper-motor-driven spider wheel having legs and gaps therebetween for receiving diverted envelopes; revolving rollers to capture and drive the skewed envelope away from the conveying path into a gap of the momentarily stationary spider wheel; and, a sensor to sense an envelope that has been driven into a spider wheel gap and, consequently, to control rotation of the spider wheel by one gap pitch.
