Title
(EN) NOZZLE AND APPLICATOR SYSTEM FOR FABRIC BONDING
(FR) BUSE ET SYSTÈME APPLICATEUR POUR LE COLLAGE DE TISSUS
Abstract
(EN)
Nozzle assemblies and methods of bonding fabric by jetting an adhesive are disclosed. A method of bonding fabrics with an adhesive includes receiving the adhesive from an adhesive supply into a nozzle assembly (100). The nozzle assembly (100) has a valve seat (104), a valve stem (48b) configured to slidably move towards and away from the valve seat (104), and a plurality of outlet channels (108). The method further includes jetting the adhesive from the plurality of outlet channels (108) onto a first fabric and applying a second fabric to the first fabric to adhere the first and second fabrics to each other.

L'invention concerne des ensembles buses et des procédés de collage de tissus par projection d'un adhésif. Le procédé de collage de tissus avec un adhésif comprend la réception de l'adhésif dans un ensemble buse (100) à partir d'une alimentation en adhésif. L'ensemble buse (100) comprend un siège de soupape (104), une tige de soupape (48b) conçue pour se déplacer de manière coulissante vers le siège de soupape (104) et loin de celui-ci et une pluralité de canaux de sortie (108). Le procédé comprend en outre la projection de l'adhésif à partir de la pluralité de canaux de sortie (108) sur un premier tissu et l'application d'un second tissu sur le premier tissu pour faire adhérer les premier et second tissus l'un à l'autre.
