ABSTRACT:
The band or belt conveyor conveys the printed products arranged in an imbricated formation to a take-over region. In the imbricated formation, each printed product lies upon the next following or trailing printed product. An outfeed device, whose conveying direction extends in the take-over region from below towards the top, comprises grippers pivotably mounted at a revolvingly driven traction element. The conveying speeds of the band or belt conveyor and the outfeed device, respectively, are co-ordinated such that in each case two infed printed products are introduced into one open gripper. The depth of the grippers is larger than the spacing or pitch between the leading product edges of the printed products in the infed imbricated formation, so that the two printed products engaged or seized by one gripper can be outfed with unchanged mutual spacing or pitch. Imbricated formations can be thus formed during delivery or outfeed of the printed products. In such imbricated formations the printed products are arranged at an imbricated spacing or pitch which is substantially the same as the original spacing or pitch.
