摘要：Uniformity of hot melt coatings on thermally sensitive plastic and other webs(1) is maintained by use of a silicone or other rubber-like web back-up roll (R₁) thedimensional stability of which is maintained during hot melt coating of the webs (1) by aheat-conducting idler roll (R₂) directly contacting the back-up roll (R₁) temperature and aheat transfer source (H) for temperature deficiencies on the silicone roll surface (R₁),aiding constant nozzle(N)-to-web (1) spacing (B) irrespective of temperature variationsand line speeds. Provision is also made for the introduction of chilling, if required.
