Abstract

Un método para aplicar un revestimiento sobre la superficiede objetos de vidrio (10), que comprende los pasos de:transportar los objetos (10) a través de un túnel de revestimiento (2); soplar un gas que incluye una sustancia generadora de revestimiento a través del túnel de revestimiento (2);caracterizado por efectuar una separación entre la atmósfera gaseosa en el interior del túnel de revestimiento (2) y el aire exterior por medio de por lo menos una cortina de gas (141, 142), consistente en un flujo que tiene un número de Reynolds menor de 8000, y preferiblemente menor de 2300, de un gas puro, preferiblemente aire puro, dicho flujo siendo sustancialmente transversal a la dirección de transporte de los objetos (10) en el túnel (2). Un aparato de revestimiento (100), que comprende: un túnel de revestimiento (2); un medio de transporte (6) para transportar objetos (10) a través del túnel de revestimiento (2); por lo menos una boquilla de soplado (31,41) dispuesta en la proximidad del medio de transporte (6); por lo menos una boquilla de descarga (36; 46) dispuesta en la proximidad del medio de transporte (6), sustancialmente opuesta a la boquilla de soplado (31; 41); caracterizado por al menos un aparato cribador de cortina de gas (111; 113) dispuesto directamente antes de una entrada del túnel de revestimiento (2) y/o directamente después de una salida del túnel de revestimiento (2), y adaptado para proporcionar por lo menos una cortina de gas (141; 142) consistente en un flujo sustancialmente laminar o flujo de transición de gas puro, preferiblemente aire puro.A method of applying a coating on the surface of glass objects (10), comprising the steps of: transporting the objects (10) through a coating tunnel (2); blowing a gas that includes a coating generating substance through the coating tunnel (2); characterized by effecting a separation between the gaseous atmosphere inside the coating tunnel (2) and the outside air by means of at least one gas curtain (141, 142), consisting of a flow having a Reynolds number less than 8000, and preferably less than 2300, of a pure gas, preferably pure air, said flow being substantially transverse to the direction of transport of the objects (10) in the tunnel (2). A coating apparatus (100), comprising: a coating tunnel (2); a transport means (6) for transporting objects (10) through the lining tunnel (2); at least one blowing nozzle (31,41) arranged in the vicinity of the transport means (6); at least one discharge nozzle (36; 46) arranged in the vicinity of the transport means (6), substantially opposite to the blowing nozzle (31; 41); characterized by at least one gas curtain screening apparatus (111; 113) arranged directly before a liner tunnel entrance (2) and / or directly after a liner tunnel exit (2), and adapted to provide for at least one gas curtain (141; 142) consisting of a substantially laminar flow or transition flow of pure gas, preferably pure air.
