Abstract
A cross gluing cylinder has spaced peripheral glue application bars which apply glue to a paper web. The overall circumferential length of the cross gluing cylinder can be changed by shifting the glue application bars and cooperating intermediate cylinder sections radially outwardly or inwardly.
Claims6
A cross gluing cylinder usable to apply glue to a movable web comprising:
- a rotatable cross-gluing cylinder;
- first and second glue application bars supported on a peripheral surface of said cross gluing cylinder, said first and second glue application bars being diametrically oppositely spaced on said peripheral surface of said cross gluing cylinder;
- means for radially shifting said first and second glue application bars for varying the circumferential length of said cross gluing cylinder;
- and
- a plurality of intermediate cylinder sections cooperating with said spaced first and second glue application bars to form said peripheral surface of said cross gluing cylinder, said intermediate cylinder sections being radially shiftable with said first and second glue application bars.
