  • Patent number: 5443678
    Abstract: The process relates to the production of a product consisting of a substrate to which an adhesive with long-term effect and a protective band are attached to permit use of the adhesive to be deferred. The process is characterized by the use of a substrate whose surface to which the adhesive is attached may present irregularities. The adhesive is heated to a temperature at which is becomes paste-like and almost liquid, and is brought to an opening situated above a plane surface on which the substrate has been placed. The adhesive is then caused to flow simultaneously with a relative movement between the substrate and the opening. This results in the adhesive being deposited on the substrate as a strand that is preferably continuous. The temperature of the adhesive is then lowered in order to increase its viscosity until it becomes paste-like to the point of turning solid.
