ABSTRACT:
Freshly printed sheets are transferred from one printing unit to another by transfer cylinders each having an ink repellent, electrically conductive, striped flexible jacket covering that is movable relative to the sheet support surface of the transfer cylinder. The jacket covering is made of a flexible fabric material that is pre-stretched, pressed flat, cut to size and treated with an ink repellent compound and is also treated with an anti-static ionic compound or is otherwise rendered electrically conductive by one or more conductive strands. Electrostatic charges carried by the freshly printed sheets are discharged through the ink repellent, electrically conductive, flexible jacket covering into the grounded transfer cylinder. A low friction, electrically conductive cylinder base covering that includes center alignment marks is secured to the transfer cylinder for engaging the flexible jacket covering. The ink repellent, electrically conductive flexible jacket covering is provided with alignment center marks and alignment stripes so that the flexible jacket covering can be precisely aligned with ease and secured over the gripper edge, tail edge and side edges of the transfer cylinder. The low frictional coefficient of the conductive cylinder base covering is further reduced by nodes and/or openings.
