Abstract (en)

[origin: EP0128873A2] The machine comprises a supporting structure (2) to which are attached an approximately vertical-axis cage (12) for stacking signatures, and conveyor means (3) arranged to receive a continuous stream of signatures and feed these signatures to the stacking cage (12). Two plattorms (18, 19) located one above the other, are movable axially relative to the stacking cage (12), the upper plattorm (18) (blade) being intended to receive the signatures fed to the stacking cage (12) and being lowerable as the signatures are stacked thereon, towards the lower plattorm (19) in synchronism with the feed movement of the signatures. The upper platform (18) can then be withdrawn from the stacking cage (12) to transfer the pile of signatures formed thereon onto the lower platform (19). Above the stacking cage (12) isaguide element for the signatures (26), this guide element (26) being at least partially movable relative to the structure (2) in the direction of stacking of the signatures themselves. The arrangement is such that the guide element (26) is kept constantly in a position of substantial contact with the last signature fed to the cage (12), its position being varied as a result of momentary variations in the speed of stacking of the signatures in order to prevent jamming of the signatures themselves.
