ABSTRACT:
Continuously conveyed flexible flat structures, especially printed products, infed in an imbricated formation, are turned such as to retain their original imbricated product formation. This is accomplished by accelerating the flexible flat structures such that they are singled and then in such singled condition are deflected about a deflection axis directed transverse to the product infeed conveying direction. Thereafter the singled turned flat structures are decelerated and transported away in an opposite conveying direction. Between an infeed device and an outfeed device for the structures there is arranged a deflection mechanism comprising at least one endless revolving driven traction element guided between its two substantially linearly extending runs about a deflection wheel. This traction element has mutually spaced outwardly extending carrier or support elements, at the outer ends of which there are mounted controlled grippers for engaging a respective one of the flat structures. The acceleration and deceleration of the controlled grippers and thus the flat structures respectively occurs during the run-on and run-off of the traction element at the deflection wheel, because then the outer ends of the outwardly protruding carrier or support elements carrying the grippers describe a substantially arcuate-shaped path which is appreciably longer than the wrapping path of the traction element about the deflection wheel.
