a laminating process in which an adhesive composition which is freely flowing or can be rendered freely flowing is discharged from a coating appliance in the form of a substantially continuous or interrupted film , out of a slot nozzle with lateral film boundaries , and is applied and fixed to the surface of at least one web - type substrate , if applicable after being deposited on an advancing transfer substrate , such as a roller , and then transferred to the web - type substrate , and in which the film is guided outward to the substrate via the nozzle slot , clamped or hemmed in at its edges by the film boundary elements , heat is drawn off to the surrounding atmosphere via at least one heat exchange element provided along the film boundary elements .
