Abstract

Dispositif pour transférer des feuilles imprimées en positionnement exact à des moyens de retournement d'une presse d'impression recto et verso, dans lequel la feuille imprimée est tendue sur un tambour de transfert à son bord arrière par des suceurs. Selon l'invention, ce dispositif est caractérisé en ce qu'au moyen d'un dispositif de succion disposé en avant du tam our de transfert et divisé au moins en deux portions, la feuille peut être aspirée au rythme de la presse et peut être aplatie par écartement du dispositif de succion transversalement à la direction de déplacement de la feuille.A device for transferring printed sheets in exact positioning to turning means of a double-sided printing press, in which the printed sheet is stretched over a transfer drum at its rear edge by nozzles. According to the invention, this device is characterized in that by means of a suction device arranged in front of the transfer drum and divided at least into two portions, the sheet can be sucked up at the rate of the press and can be flattened by spreading the suction device transversely to the direction of movement of the sheet.
