Transporting roller, holding-down means and transporting system for flat articles

Abstract

The invention relates to transporting rollers () for transporting essentially flat articles, to holding-down means () for pressing the articles onto transporting rollers (), and to a transporting system (). In this case, the transporting roller () is of at least two-part configuration and comprises a spindle element and at least one track element (), the latter enclosing the spindle element in a tubular manner. The invention consists in designing transporting rollers () such that the spindle element is flexurally rigid, and in presenting an essentially cylindrical holding-down means () which is of at least two-part configuration and comprises a spindle () and at least one sleeve (), wherein the internal diameter of the sleeve is larger than the external diameter of the spindle, the spindle () and the sleeve () of the holding-down means are coupled, and a pin-like carry-along element which is oriented away from the spindle () and engages in a cutout () on at least one side of the sleeve () is fitted on the spindle (). The invention allows articles to be processed continuously, while keeping to the correct track as precisely as possible, with careful handling, in the case of which, under a wide range of different conditions in respect of temperature, pressure and surrounding medium, the workpieces are exposed to only a low level of mechanical loading.
