Abstract
A support cylinder for guiding freshly processed substrate material between printing units or at the delivery end of a printing press is provided with a low coefficient of friction, semi-conductive covering for supporting and transporting the freshly processed substrate material without smearing the ink or causing indentations on the surface of the substrate. Radially projecting surface portions define electrostatic precipitation points and reduce the surface area available for frictional engagement. The low friction and electrostatically neutral properties of the semi-conductive base covering permit free movement of the freshly processed substrate relative to the support cylinder surface. Electrostatic charges carried by the processed substrate are discharged through the semi-conductive base covering into the support cylinder, thus eliminating electrostatic cling attraction between the freshly processed substrate and the support cylinder.
