At a conveyor device following an infeed conveyor, individually controllable grippers are arranged in spaced relationship at a revolvingly driven buffer chain. These grippers serve to engage folded printed products at their leading edges and which are infed in imbricated formation. The links of the buffer chain are interconnected by pivot bolts. These pivot bolts are alternately displaceably mounted in guide members. By reducing the spacing between these guide members, there is increased the spacing between the grippers. By increasing the spacing between the guide members it is possible to again reduce the spacing between the grippers. At a product take-over region the printed products are engaged by the grippers. At a subsequently arranged product acceleration region the spacing between the grippers is enlarged so that the printed products, in this acceleration region, no longer are in overlapping formation. At a product singling region a drag drive acts upon the links of the buffer chain. In a subsequently arranged product deceleration region the spacing between the grippers is again reduced and the printed products are placed into a suspended position. In subsequent product transfer region, the printed products are delivered to an outfeed conveyor.
