发明名称 ROLL COVER APPARATUS
摘要 A roll cover apparatus (12) is disclosed for covering a roll (14) of a papermaking machine. The apparatus includes a synthetic cover (16) which is applied to the outer peripheral surface (18) of the roll, which is of an electri-cally conductive material. A plurality of fibers (20, 21, 22) are randomly dispersed within the synthetic cover such that the plurality of fibers are disposed between the outer peripheral surface of the roll and an outer face (24) of the synthetic cover. An electrically conductive material (26) is applied to the external boundary (28) of at least some of the fibers (20, 22) such that during use of the apparatus, when slippage occurs between a web of paper (W) being treated by the apparatus and the outer face (24) of the cover, an electrostatic charge (30) generated by the slippage is discharged by the conductive material (26) from the outer face of the cover to the electrically conductive roll (14) so that scorching of the web by discharge of the charge (30) through the web is eliminated.
