In order to stack sheets of paper or cardboard (1) transported by a stream feeder onto pallets (4), devices are known which comprise a stacking platform (5) which can be raised and lowered, and on which the piles (3) are formed. During the stacking process, the longitudinal edge of a sheet (1) is guided by a separating plate (12) which is suspended on a holding element fixed in the machine frame, and is connected to a vibrator (13) in the form of a shaking element. According to the invention, in order to improve the shaking effect of the separating plate (12), a holding plate (18) is fixed, by means of rubber elements (19), to the holding element fixed in the machine frame, in such a way that it is decoupled from vibrations, the separating plate (12) and vibrator (13) being suspended from the holding plate in a rigid manner.

Pour empiler des feuilles (1) de papier ou de carton transportées par margeur à nappe sur des palettes (4), les dispositifs connus comportent une plate-forme (5) pouvant être levée et abaissée, sur laquelle les piles (3) peuvent être formées. Le bord longitudinal d'une feuille (1) est guidé, lors de l'empilage, par une tôle de séparation (12) suspendue à un support fixé au bâti de machine et reliée à un vibrateur (13) en tant qu'élément d'agitation. Selon la présente invention, pour améliorer l'effet d'agitation de la tôle de séparation (12), une plaque de retenue (18) est fixée par l'intermédiaire d'éléments en caoutchouc (19) de manière à être découplée des vibrations à un support fixé au bâti de machine, la tôle de séparation (12) et un vibrateur (13) étant suspendus de manière rigide à ladite plaque de retenue.
