Title:
WEB SMOOTHNESS IMPROVEMENT PROCESS
Document Type and Number:
WIPO Patent Application WO2003085192
Kind Code:
A9
Abstract:
The present invention provides a process for improving smoothness of a web surface by subjecting the web surface to an untreated smooth roll traveling at a different speed than the web and thereby producing heat generated by friction to plasticize the very top fibers in the mat. Surprisingly, the inventors found that no abrasive was needed to generate the amount of heat required to achieve the smoothness gain.
