Abstract (en)

[origin: WO0189971A1] The invention relates to a method and device for the merging and finishing of at least two paper webs (1, 2, 3, 4), controlled in the longitudinal register, which are distinctly different in quality and in finishing steps to be undertaken. The device comprises at least two web-specific processing regions (13A, 13B, 13C), a merging unit (21), a common processing region (22), controlled in the longitudinal register and means for the control of the longitudinal register (14), essentially comprising one longitudinal register sensor per paper web. Markings are placed on the paper web with periodic separations. Longitudinal register sensors (14) recognise said markings and transmit signals to the control unit, which determines possible variations and controls the means for regulation of the longitudinal register in such a way that variations in the longitudinal register are compensated. The device further comprises means for setting the web tension of the individual paper webs, with at least two tension-adjusting devices (19A-D, 20A-D) in the course of the paper webs and, on at least one paper web, at least three adjusters, with which the web tension may be adjusted independently of each other in at least two partial regions, defined by the above. The partial regions preferably essentially correspond to the web-specific and the common processing regions. The web tension in the web-specific processing regions can thus be optimally adjusted to match the paper quality and the finishing process requirements.
