ABSTRACT:
A device is provided in a reel-up in a paper machine in which paper is produced in a web running in the reel-up and supported by a surface winding drum and wound onto exchangeable reeling drums in contact with the surface winding drum in order to form reels of paper. The device applies an adhesive agent on the web when changing full-width reels and in the event of web ruptures in the reel-up. A screen is mounted on the stand of the reel-up, upstream of the surface winding drum, and extending transversely to the machine direction. A spray rack, supported by the screen, extends transversely to the web across its entire width and comprises a plurality of nozzles distributed uniformly across the web to spread spray jets of liquid containing said adhesive agent onto the web to form a coherent adhesive area perpendicular to the machine direction. The adhesive area is brought into contact with an empty reeling drum or an already commenced reel of paper.
