Abstract
A gatherer-stitcher has a folded-sheet feeder and an apparatus for transferring folded sheets from the feeder to a transporting configuration of the gatherer-stitcher. The apparatus has a plurality of shafts or drums with grippers for gripping the folded sheets. The apparatus opens the folded sheets and places them astride the transporting configuration. The apparatus also has a blowing configuration which, as a folded sheet is transferred from one shaft or drum to another, subjects the folded sheet to a surge of air in time with a folded-sheet transportation.
