PROCESS FOR BONDING WEBS

An improved method for bonding webs. The method includes overlapping two webs, slitting the two webs (10, 11), reoverlapping the two webs and bonding the two webs together. The steps of reoverlapping the two webs may be accomplished with a number of different types of devices including but not limit...

Beschreibung
Zusammenfassung:	An improved method for bonding webs. The method includes overlapping two webs, slitting the two webs (10, 11), reoverlapping the two webs and bonding the two webs together. The steps of reoverlapping the two webs may be accomplished with a number of different types of devices including but not limited to: a bumpered roll (12), a notched roll (13), a crowned roll, a bowed roll (14), an out of plane roll, and variable speed rolls. La présente invention concerne un procédé perfectionnant la liaison entre nappes. Ce procédé consiste à superposer deux nappes, à fendre les deux nappes (10, 11), à superposer de nouveau les deux nappes, puis à lier les deux nappes entre elles. Les opérations de nouvelle superposition peuvent se réaliser en employant plusieurs types de dispositifs différents comprenant notamment un cylindre à bosses (12), un cylindre à encoches (13), un cylindre bombé, un cylindre incurvé en creux (14), un cylindre hors plan, et des cylindres à vitesse variable.
