ABSTRACT:
A turnover-sequencer staging apparatus for sheets comprises: a receiver, a turnover-sequencer, and a staging segment. The receiving device receives at least two side-by-side sheets and supplies these to the turnover-sequencer wherein the sheets are overturned and rerouted in a substantially orthogonal direction, the relationship between sheets having been converted to sequential whereby the sheets become disposed seriatim and imbricated. The overturned and rerouted seriatim-imbricated sheets are selectively de-imbricated in the staging segment by separation of selected consecutive sheets. Separation is effected by braking or stopping of the conveying motion of the trailing one of two consecutive sheets. In other embodiments, separation can be accomplished by changing the speed of conveying of one of two consecutive sheets; either by speeding up of the leading sheet or by slowing down of the trailing sheet.
