ABSTRACT:
Apparatus for opening folded paper sheets, each of which has a first and a second set of layers and each of which has an edge portion along which the layers are pivotable relative to each other, has a horizontal conveyor which transports each of a succession of folded sheets in such a way that the edge portion is located at the top and the layers extend downwardly. A group of suction heads, one for each layer of a set of layers, is adjacent to one side of the path of movement of successive folded sheets, and the suction heads orbit about axes which are inclined with respect to the vertical so that each suction head moves upwardly during that stage of each of its orbital movements when it approaches and attracts the respective layer and flexes it outwardly whereby the inner side of the layer can be intercepted by a stationary retaining element which follows the respective suction head. The foremost suction head flexes the outermost layer of a set of layers, the next suction head flexes the next-to-the outermost layer, and so forth.
