Abstract

The device for joining at least two paper strips (1a-1e) to form a paper web comprises two sandwich rollers (3) between which the paper strips are fed and from which they are brought together to form a web. First and second rollers are used, which have a highly conductive or semi-conductive outermost layer (34). Charging devices are available, which electrically charge the outermost layer of the first roller. The device incorporates an inductor electrode (2), arranged at a distance from the first roller. A further inductor electrode is spaced from the second roller, the outermost layer of which is charged electrically with a counterposed charge to that of the first roller. The first and/or second rollers have/has a semi-conductive outermost layer (34), beneath which is a highly conductive layer (33) and beneath which is an insulating layer (32) and a core (31).
