FIELD: adhesives.
SUBSTANCE: invention relates to a system and method for applying an adhesive composition to a moving belt of material. During the process, the belt of material is transported very quickly next to the nozzle of the glue applicator. The deflection device periodically deflects the belt into contact with the nozzle surface. An adhesive flow control device is used to control the flow of adhesive through the nozzle. The adhesive flows through the nozzle and is synchronized with the deflection device. In one version, the flow of adhesive is initiated prior to contact with the tape. In this way, treated discrete areas of the adhesive composition can be formed on the tape.
EFFECT: treated discrete areas can have lengths that are minimized by the process of the present invention, which allows the adhesive to be applied at extremely high speeds.
