ABSTRACT:
Uniformity of hot melt coatings on thermally sensitive plastic and other webs is maintained by use of a silicone or other rubber-like web back-up roll the dimensional stability of which is maintained during hot melt coating of the webs by a heat-conducting idler roll directly contacting the back-up roll temperature and a heat transfer source for temperature deficiencies on the silicone roll surface, aiding constant nozzle-to-web spacing irrespective of temperature variations and line speeds. Provision is also made for the introduction of chilling, if required.
