ABSTRACT:
In a process for applying a partial surface coating to a textile substrate, the textile substrate is unwound from a supply roll, preheated to a preheating zone and partly coated in a coating station by a coating head having coating nozzles. The coating compound is melted and supplied to the coating head. The heated coating head is provided within a perforated cylinder. The nozzles of the coating head apply melted coating compound through the perforations in the cylinder onto the substrate. Hot air is applied in the vicinity of a rising portion of the perforated cylinder facing the substrate to provide a clean breaking off of the melted compound from the surface of the perforated cylinder during the application of the coating onto the substrate.
