Title (EN) METHOD AND APPARATUS FOR APPLYING NARROW, CLOSELY SPACED BEADS OF VISCOUS LIQUIDS TO A SUBSTRATE
(FR) PROCEDE ET APPAREIL D'APPLICATION DE PERLES ETROITES, A ESPACEMENT SERRE DE LIQUIDES VISQUEUX SUR UN SUBSTRAT
Abstract:
(EN) Apparatus (10) for applying multiple narrow, closely spaced beads of viscous liquid (12), such as hot melt adhesive, to a substrate (14) comprises first and second blades (100 and 102) between which there is a thin shim (104) having a plurality of parallel, closely spaced slots (18) open to and in fluid communication with a slot cavity (112) in one of the blades such that high pressure, viscous liquid supplied to the slot cavity (112) exits onto the substrate (14) from between the blades through the slots (18) in the shim (104).
(FR) Appareil (10) d'application de perles multiples, étroites, à espacement serré d'un liquide visqueux (12), tel qu'un adhésif de fusion à chaud, sur un substrat (14). L'appareil comprend des première et seconde lames (100 et 102) entre lesquelles est placée une cale mince (104) présentant plusieurs fentes parallèles étroitement espacées (18) débouchant dans une cavité (112) et en communication fluide avec cette cavité ménagée dans l'une des lames de sorte qu'un liquide visqueux à haute pression envoyé dans la cavité (112) sort sur le substrat (14), en passant entre les lames et au travers des fentes (18) de la cale (104).
