Abstract

An apparatus for processing folded printed sheets includes a work station for processing the folded printed sheets and a conveying device driven with a transporting movement in a direction along a conveying path that is arranged alongside the work station. Saddle-shaped supports are attached to the conveying device and have supporting edges on which the printed sheets can be supported respectively along their fold by straddling the supporting edge of the respective saddle-shaped support. The saddle-shaped supports are conveyed along the conveying path so that the supporting edges are positioned transverse to the conveying path at a distance to each other and move successively past the work station which cooperates with the saddle-shaped supports respectively while the saddle-shaped supports are transported past the work station. A mechanism movably attaches the saddle-shaped supports on the conveying device and guides the respective supporting edges along a movement path in which, in a region of cooperation with the work station, a relative speed component of the supporting edges parallel to the conveying path, with respect to the work station, is smaller than a relative speed for …
