For the horizontal positioning of serially supplied, flat objects (1) to be conveyed onward, the objects (1) are supplied suspended, one of their main surfaces (10) facing downstream and the other main surface (11) facing upstream. Prior to positioning, lower edge zones (13) of the objects (1) are selectively accelerated or retarded relative to the upper edge zones (12), so that the objects (1) are brought into a position inclined relative to the vertical. Thereupon the upper edge zones (12) are released and the objects (1) with the assistance of the force of gravity are positioned on an onward conveying means, selectively either the downstream or the upstream main surface (10 or 11) facing upwards. For retarding. resp., accelerating the lower edge zones (13), for example, a conveyor belt or two conveyor belts adjoining one another is or are utilized, the speed (v.3) of the conveyor belts being adjustable for a conversion from accelerating operation to retarding operation. The principle advantage of the method and device described is the easy convertibility. Method and device, for example, can be utilized for collating printed products or printed part products.

Pour le positionnement horizontal d'objets plats (1) fournis séquentiellement en vue d'être convoyés, les objets sont suspendus, l'une de leurs surfaces principales (10) se trouvant en aval et l'autre surface principale (11) en amont. Avant ce positionnement, le rebord inférieur (13) des objets est ralenti ou accéléré de manière sélective par rapport à leur rebord supérieur (12), de manière que les objets sont inclinés. Le rebord supérieur est alors relâché et les objets, suivant la force de gravité, sont déposés sur un transporteur à courroie en mouvement, la surface principale avant ou arrière tournée vers le haut. Pour ralentir ou accélérer la position du rebord inférieur des objets, on fait appel à un ou deux transporteurs à courroie contigus dont la vitesse (v.3) peut être réglée pour passer de l'accélération au ralentissement. Le principal avantage de la méthode et du dispositif décrits ici est leur grande polyvalence, tous deux pouvant servir, par exemple, à l'assemblage de produits d'imprimerie ou de pièces d'imprimerie.
