Device for decelerating and/or accelerating printed sheets or exemplars separated from a sheet like print substrate

摘要

The apparatus has two devices (13, 14) rolling on an upper side and a lower side of a printed sheet and/or exemplar (11), respectively, where the devices are coated with polyurethane at its contact areas (15, 16). The devices are driven by using a drive in such a manner that the contact areas comprise a circumferential speed when the devices contact the printed sheet and/or the exemplars, where the circumferential speed corresponds to an initial speed of the printed sheet and/or exemplars.
