<p>PURPOSE:To make the peelability of paper ever so better and simultaneously improve durability in a feeding device as well as to prevent a contact failure from occurring, by installing a conductive contact maker embeddedly in a conductive ground layer, which has lamellarly unitized a feeding brush on an insulating support body layer. CONSTITUTION:A feeding brush 3 consists of an insulating adhesive 11 applied to the surface of a support body of an insulator, a ground layer 12 composed of a conductive fiber and a contact maker 13 of a conductive fiber embeddedly installed in this ground layer 12. The contact maker 13 being energized with current via the ground layer 12 comes into contact with each of strip electrodes 5a and 6a of first and second electrodes 5 and 6, and impresses the voltage. When high voltage is impressed in space between paired brushes 3 from a DC power source E, these electrodes 5 and 6 are energized with a continuous rating current via these strip electrodes 5a and 6a whereby electrostatic suction force is produced in a suction film layer 7, peeling paper from the top of a belt 2, thus shifting from conveyance to discharge is smoothly carried out. In addition, the contact maker 13 will in no case bring about a contact failure due to wear by friction with these strip electrodes 5a and 6a.</p> |
