ABSTRACT OF THE DISCLOSURE A sticky, plastically deformable material, particular- ly an adhesive bead, is cut by means of a jet-like cutting me- dium, preferably by means of a fluid jet, particularly by means of an air jet having a diameter of approximately 0.15 mm and a pressure of between 80 to 100 bar. The method can be used in a method of automatically applying a profiled adhesive bead to the surface of a glass pane along the edge thereof. Thereby, the adhesive material is extruded through a profiled extruding nozzle. The extruding nozzle is led along the edge of the glass pane by means of a robot. Simultaneously, that portion of the extruded adhesive bead which lies in the region of the start point of the extrud- ing nozzle and which does not have the desired final shape is cut off from that portion of the extruded adhesive bead which has the desired final shape by means of a first cutting opera- tion performed in a direction transverse to the extension of the adhesive bead. Then the portion of the adhesive bead which does not have the desired final shape is removed from the sur- face of the glass pane. Finally, the profiled adhesive bead extruded by said extruding nozzle is cut to such a length that the two free ends of the adhesive bead congruently touch each other by means of a second cutting operation performed in a direction transverse to the extension of the adhesive bead and running parallel to the direction of the first cutting opera- tion.
