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.

Abstract: The described process involves the production of a product comprising a fibrous substrate to which an adhesive with long-term effect and a removable protective strip are applied in order to permit use of the adhesive to be deferred. The process is particularly useful with substrates whose surface to which the adhesive is applied contains irregularities. The adhesive is heated to a temperature at which it becomes paste-like and readily flowable 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 to be deposited on the substrate as a strand that is preferably continuous. The temperature of the adhesive on the substrate is then lowered in order to increase its viscosity until it becomes paste-like just prior to the point of turning solid.
