Abstract

A delivery fan, comprising sets of blades at constant circumferential spacings, receives therebetween the sheets successively falling from an overhead infeed conveyor. The sheets fall off the delivery fan on hitting a set of abutment tines arranged interdigitatingly with the fan blades. A stack of sheets thus formed on a retractable platform is unloaded therefrom onto a delivery conveyor. A temporary sheet holder is provided which is angularly displaceable about the delivery fan axis between a working position, where it temporarily receive the sheets falling off the delivery fan pending unloading of the preformed stack of sheets, and a retracted position where the sheet holder allows the sheets to fall from the delivery fan onto the platform. The sheet holder is mounted to the shaft of the delivery fan via a pair of overrunning clutches and sprung from the retracted toward the working position. Consequently, when unlocked from its retracted position upon stacking of the sheets to a predetermined height on the platform, the sheet holder turns to the working position at the same angular velocity as the delivery fan.
