A process and device are disclosed for applying an elastoplastic band as a spacer when producing insulating glass panes. The device comprises a take-off reel for the band, a plurality of driven band-guiding rollers and a band compression head movable relative to a first glass pane. Unlike in the prior art, an elastoplastic band is used whose lateral surfaces are not coated with an adhesive. Instead, the adhesive is applied to the band shortly before the band is applied. For this purpose, opposite nozzles are arranged between the take-off reel and the compression head and coat the band lateral surfaces with adhesive.

Ce procédé et ce dispositif permettent d'appliquer une bande élastoplastique (1) comme élément d'écartement lors de la fabrication de plaques de verre isolant. Le dispositif comprend un dévidoir (2) de bande, une pluralité de rouleaux entraînés (4, 6, 7, 8) de guidage de la bande et une tête (20) de compression de la bande mobile par rapport à une première plaque de verre (40). Au contraire de l'état de l'art, on utilise une bande élastoplastique dont les surfaces latérales ne sont pas enduites d'adhésif. L'adhésif est plutôt appliqué sur les deux surfaces latérales de la bande immédiatement avant son application. A cet effet, des ajutages opposés (11, 12) sont agencés entre le dévidoir (2) et le tête de compression (20) et enduisent d'adhésif les surfaces latérales de la bande.
