    Abstract: A method and apparatus for applying a coating of a hot flowable adhesive to one surface of a thin flexible substrate. The adhesive is heated to above the degradation temperature of the substrate, so as to coat the substrate. The adhesive is first applied to an intermediate carrier sheet while the opposite surface of the intermediate carrier sheet is in intimate contact with a heat sink, the heat sink being cooled to a temperature substantially below the degradation temperature such that heat is conducted away from the intermediate carrier sheet so that the intermediate carrier sheet does not reach its degradation temperature and is consequently undamaged. The adhesive is then contacted to a surface of a substrate that it is desired to coat with adhesive, while said adhesive is still above the minimum bonding temperature of the adhesive. This allows the adhesive to bond to the substrate. The adhesive is then cooled and bonded to the substrate permitting later removal of the intermediate carrier sheet.
