Abstract (en)
For transferring single sheets from a stack (16) to a receiving or working plane (14a) a device is used provided with a series of suckers (48) transversally aligned with respect to the transfer direction of the sheets and connected to a vacuum source consisting of an ejector (182, figure 6) actuated by a compressed air source (170) with which the device is provided, such a series of suckers (48) being movable between two positions, lifted and dropped respectively on the top sheet (17) of the stack (16) of sheets to be transferred and being integral with a carriage or slider (50) movable in the direction of the sheet transfer against the opposing action of a return spring (162). The synchronisation of the different movements is provided by a plurality of cams (32, 34) mounted to a single cam shaft (30) rotated by a motor (20) timely actuated with the single steps of the operating cycle of the sheet placing device. <IMAGE>
