ABSTRACT:
The transport apparatus comprises an endless guide device extending in a closed path and at which there are guided a number of entrainment elements. These entrainment elements are interconnected by a toothed belt deformed into a substantially wave-shaped configuration by attachment elements secured at the entrainment elements. At each of the starting region and terminal region of the conveying-active path of the transport apparatus, there are rotatably mounted two parallel cam discs rotatable in a predetermined direction of rotation by related drives. Recesses in the cam discs act upon the entrainment elements such that the latter are driven at the starting region and terminal region of the conveying-active path and are dispositioned in a predetermined mutual position. The spacing between the entrainment elements at the conveying-active path and at the non-conveying active path is compensated by the resilient action of the wave-shaped deformed toothed belt. Differences in the operating cadence or in the phase position between printed products delivered to the transport apparatus and outfed away therefrom are compensated by increasing or reducing the spacing between the entrainment elements.
