ABSTRACT:
A conveying method permits conveying of printed products, particularly in the form of a scale flow, with a constant or variable speed over conveying distances of random length, which can also contain rising or falling portions in the conveying direction, as well as curves. The method is based on the fact that each individual printed product or small group of printed products is conveyed by a conveying a element over a step length (S) which is small compared with the entire conveying distance and is then taken over by the next conveying element, while the first conveying element is moved back to its starting point. This process is repeated in a time cycle with the cycle length (T). The corresponding apparatus comprises a fixed support and a plurality of conveying elements, which are driven in a timed manner. A conveying distance or section can comprise a plurality of conveying modules, no transfer units being required between the individual modules. All the modules of a conveying section operate with the same timing cycle.
