发明名称 METHOD AND ASSEMBLY FOR GUIDING A WEB OF PAPER OR BOARD WEB DURING MANUFACTURE
摘要 Method and assembly for guiding a web of paper or board or, alternatively, a n edge strip sheared therefrom, in a paper machine or finishing equipment, the method being particularly suited for threading the web tail or edge strip through the machine in conjunction with a production shutdown or after a web break. According to the invention, the web (6) or its tail sheared from the web so as to form an edge strip is supported electrically by means of taking surfaces or electrodes (3, 5) disposed on opposite sides of the web (6) to different potentials. Particularly advantageously, the web (6) or the edge strip can be adhered to a roll (16), a belt (7) or a wire by taking said support element to a lower potential and disposing a higher-potential electrode (5) or a number of electrodes to the opposite side of the web.</SD OAB>
