Abstract

La presente se refiere a un aparato dispensador que comprende unidades de válvulas primera y segunda (9, 10), cada una de las cuales tiene una salida para entregar un líquido bajo presion; un medio para la aplicacion de líquidos acoplado a dichas unidades de válvula, teniendo el medio para la aplicacion de líquidos una superficie de contacto (2) y por lo menos dos salidas separadas, co-extensivas (5; 6) en dicha superficie de contacto que se comunican independientemente con dichas salidas de dichas unidades de válvula primera y segunda, desembocando dichas salida co-extensivas en sucesion dentro de un canal (7) que está rehundido con respecto a dicha superficie de contacto; desembocado dicha canal en un extremo de arrastre de dicha superficie de contacto además de tener una seccion transversal de flujo que aumenta escalonadamente para cada líquido adicional que se descarga sucesivamente a través de dichas salidas co-extensivas. La presente se refiere también a un método para dispensar líquidos con un sustrato que se mueve en una direccion de avance bajo contacto con un aparato dispensador, que comprende el paso de formar mediante dicho aparato un filamento de líquidos combinados sobre el sustrato, en el que el segundo líquido se transforma en un filamento que encapsula el primer líquido previamente dispensado sobre el sustrato.This refers to a dispensing apparatus comprising first and second valve units (9, 10), each of which has an outlet for delivering a liquid under pressure; a means for the application of liquids coupled to said valve units, the means for the application of liquids having a contact surface (2) and at least two separate, co-extensive outlets (5; 6) on said contact surface that they independently communicate with said outputs of said first and second valve units, said co-extensive outlets flowing in succession into a channel (7) that is recessed with respect to said contact surface; said channel into a trailing end of said contact surface in addition to having a cross section of flow that increases stepwise for each additional liquid that is successively discharged through said co-extensive outlets. The present also refers to a method for dispensing liquids with a substrate that moves in a forward direction under contact with a dispensing apparatus, comprising the step of forming by means of said apparatus a filament of combined liquids on the substrate, in which The second liquid is transformed into a filament that encapsulates the first liquid previously dispensed on the substrate.
