For conveying flat articles (10) in dense conveying streams, grippers (3) conveyed one behind the other by conveying elements (1) are used, each gripper (3) holding one of the articles gripped in an edge zone. For increasing the possibilities for changing the orientation of the flat articles (10) during such conveyance, the grippers (3) are attached to the conveying elements (1) by asymmetrically-projecting gripper arms (2) and the grippers (3) are designed to be rotated through 360° around the gripper arm axis. The device can be used universally, particularly for held conveyance of printed products and it is very easily adjustable for differing applications.

Apparatus as claimed in one or more of the claims 1 to 5, characterised in that it comprises a second sensor for detecting that the rear end of the sheet (9) has left the printer (1). 7. Apparatus as claimed in one or more of the claims 1 to 6, characterised in that a measuring device is associated with the second pair of roller means (33, 24), said measuring device registering the length of the sheet. 8. Apparatus as claimed in one or more of the claims 1 to 7, characterised in that the roller means (23, 24, 33) are provided with overrunning clutches so as to ensure that the sheet can be pulled freely forwards in the advancing direction when the advancing device of the printer (1) starts to advance the inverted sheet (9). 9. Apparatus as claimed in one or more of the claims 1 to 8, characterised in that a redirecting member (42) is provided for directing the front edge of a sheet at the guiding slit (18) in a direction downwards and into said guiding slit (18) at the arrival from the printer (1). 10. Apparatus as claimed in claim 9, characterised in that the redirecting member (42) comprises a Z-shaped sectional guide freely pivotally journalled about a horizontal axis above the outlet area (12), where the body of said Z-shaped sectional guide in the rest position extends obliquely downwards and abuts by its lower end the edge of the upper guiding wall (13) of the guiding slit (18) adjacent the printer (1), and together with this guiding wall (13) it forms an acute angle facing the outlet area (12) while the lower web (46) of the sectional guide projects obliquely upwards from the guiding wall (13) towards the printer (1). 11. Apparatus as claimed in one or more of the claims 1 to 10, characterised in that the frame (16) is tiltably and detachably mounted on the support (2) of the printer (1). 12. Apparatus as claimed in one or more of the claims 1 to 11, characterised in that an additional guide (38, 41) is provided between the two pairs of roller means (23, 24, 33) and the second pair of roller means (24, 33) and the outlet area (12), respectively.
