The invention concerns a method for application of an adhesive or equivalent onto a moving material web, wherein the adhesive is applied by means of at least one applicator device (20) through at least one nozzle (30) onto the face of the material web to consititute an adhesive strip (G) in the longitudinal direction of the material web (W). In the method, the material web (W) is made to run at an invariable distance from the nozzle (30) end placed next to the material web (W). The adhesive is passed onto the material web (W) through the nozzle (30) in the applicator head (31) of the applicator device (20), and the applicator head (31) and the nozzle (30) for the adhesive are washed for the next cycle of use in a container space (23) in the applicator device (20). Further, the invention concerns a device for application of an adhesive or equivalent onto a moving material web (W), which device (20) comprises frame constructions (21, 22, 23), an adhesive-applicator head (31), a container spaced (23), and at least one adhesive nozzle (30). The applicator head (31) is provided with a support face (38) or support faces (34, 35), over which the material web (W) is passed so that the adhesive nozzle (30) is placed at a invariable distance from the material web (W). The device (20) comprises means (32, 33, 34) for transferring the applicator head (31) into the container space (23) and means (24) for washing same. Also, the invention concerns an adhesive nozzle for an adhesive-applicator device.
