Abstract: The present subject matter relates to systems and methods for advancing booklets from a group of booklets are provided. In particular, a booklet feeder can include a conveying path for supporting a group of booklets with each booklet comprising a stack of bound sheet articles, and a grip remover configured for engaging booklets in a seriatim manner in the conveying path. The grip remover can be movable to remove an engaged booklet from the conveying path and advance the removed booklet to an exit path.

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.
