A web-fed printing press with apparatus for the making of a longitudinal fold in the conveying direction of the printed copies, the longitudinal fold being preferably produced after a cylinder cross-fold. The folding device includes a folding blade disposed parallel to the conveying direction, the folding blade being moved in a reciprocal vertical fashion through the intermediary of drive cranks. Without sliding guide parts, the vertical reciprocating motion is executed towards the printed copy, and the additional crank is driven through the intermediary of a toothed belt. |
