ABSTRACT:
Cellulosic webs can be embossed using an extended nip structure with embossing means in a controlled nip dwell zone. Single and multiply wipes and towels produced by plying together two or more such webs can be embossed. Webs having common caliper and basis weight can be processed using the extended nip structure with an appropriate embossing means. The tendency of the embossed relief to relax and disappear after processing can be substantially alleviated by controlling dwell time to ensure reliable embossing.
