The conveyor device comprises rollers, located side-by-side at a distance apart, whereof the axes are located in one plane and which have the same diameter. The roller at one end can be driven by the rotating inlet roller of a printing unit and all the rollers are connected to each other in pairs and preferably by an endless toothed belt respectively, so that they are driven in synchronism with the conveying speed of the printing units. The tangential plane located on the upper side of all the rollers defines the plane in which the sheets are conveyed. Located between the rollers are stationary guide plates the surfaces of which are located in the conveying plane. Mounted above each roller are pressure rollers, which are each provided on their periphery with a rubber ring and which are pressed by springs against the rollers. This conveyor device for sheets to be installed between two printing units is particularly suitable for sheets having a small format, which are already cut to their final format. |
