METHOD OF TREATING A WEB USING AN APPARATUS HAVING A CENTER BEARER RING

摘要

A method of treating a web includes directing the web toward an apparatus having a first roller and a second roller together defining a nip. The first roller is rotated in a first direction and includes two ends, a length extending between the two ends, a raised area adapted to treat the web, and a bearer ring. The bearer ring extends around the circumference of the first roller and is disposed at a location between and spaced from the ends of the first roller. The second roller of the apparatus is rotated in a second direction opposite to the first direction. The web is fed to the nip of the apparatus such that the web is contacted by the raised area on the first roller to treat the web.
