STATIC REDUCTION ROLLER AND METHOD FOR REDUCING STATIC ON A WEB

摘要

The present disclosure describes a looped pile static reduction roller (100, 200, 300), an apparatus (400) including the looped pile static reduction roller, and a technique to neutralize static and static patterns from a polymeric film surface during processing, to enable higher speeds and fewer defects during web transport. The looped pile static reduction roller includes a static reduction engagement cover (160, 260, 360) that is resilient and can facilitate discharge of static from the web to ground before, during, and after contact with a charged web (320, 420).

主权项

1. A static reduction roller, comprising:
a roller having a low-conductivity major surface, a central axis, and two ends; a static reduction engagement cover having an inner surface and an outer surface, the inner surface adjacent the major surface of the roller, the static reduction engagement cover comprising:
a resilient engagement surface; andelectrically conductive fibers,wherein the electrically conductive fibers are disposed throughout the resilient engagement surface such that a portion of the electrically conductive fibers are proximate the outer surface.
