ABSTRACT:
An apparatus is disclosed for assisting in the release of a web from contact with the heated surface. The apparatus includes a material which is urged into contact with the heated surface upstream relative to the contact of the web to the heated surface. The material is devoid of metallic content and the arrangement is such that when the web contacts the heated surface downstream relative to the material, thermal energy is transferred from the surface to the web. The web is released from the heated surface subsequent to the transfer of the heat, such release being facilitated by the material being urged against the surface.
