Abstract (en)

[origin: EP0656434A1] The pressure roller possesses a roller core (1) and a covering (3) attached to the roller core (1) and consisting of elastomeric material. It is characterised by an addition of finely distributed electrically conductive material, for example metal powder, at least in the region of the circumferential surface of the covering (3). The electrically conductive material can be contained in a coating (4) arranged on the circumferential surface of the covering (3). The pressure roller is intended for cooperation with a drivable counter-roller (5) for the movement of fibre material. The addition of electrically conductive material counteracts electrostatic charges, primarily when the charges may be derived, and thus reduces the risk that fibres from the fibre material to be moved are wound on to the pressure roller during operation. <IMAGE>
