Abstract

Dispositif de transport avec des compartiments de transport (2) pouvant être déplacés les uns à la suite des autres le long d'une voie de transport, qui présente des surfaces porteuses (S) disposées dans les compartiments de transport et sur lesquelles des objets plats (G), notamment des produits imprimés, peuvent être transportés à plat. Les surfaces porteuses (S) sont chacune formées par une bande porteuse (5) souple. Afin de régler différents angles entre la surface porteuse (S) et la voie de transport (1), chaque compartiment de transport (2) présente un élément de réglage (3) qui agit sur la bande porteuse (5) dans une région située entre deux extrémités de bande qui sont fixées en deux points de fixation (10, 11) mutuellement distants et parallèles à la voie de transport (1). L'élément de réglage (3) est en outre conçu pour, dans un compartiment de transport voisin (2'), presser des objets (G) contre la surface porteuse (S), permettant ainsi un transport pendant lequel la surface porteuse (S) est très inclinée ou est disposée au-dessus des objets (G). Le dispositif de transport convient notamment pour regrouper des objets plats (G) et pour transférer sélectivement les objets regroupés à un autre dispositif de transport.
