ABSTRACT:
Folded printed sheets are delivered by a first conveyor into the radially extending pockets of a turret-shaped second conveyor for delivery onto successive saddles of a gathering conveyor which transports stacks of superimposed interfitted folded sheets to a stapling apparatus. The fold lines are disposed at the leading ends of sheets which enter the pockets of the second conveyor to engage suitable abutments, and the sheets are thereupon acted upon by centrifugal force to move radially outwardly against stops in their pockets prior to being withdrawn and simultaneously partially spread out for deposition on the oncoming saddles of the gathering conveyor. The second conveyor rotates about a horizontal axis which is located at a level above the gathering conveyor and at the level of or below the discharge end of the first conveyor.
