The invention relates to a sealing profile (1) with partial colouring for windows, windscreens, sliding roofs, doors or similar vehicle parts, the sealing profile being made of rubber and having at least a partial colouring (2), which is in the form of a layer. By means of an on-line process, the profile (1) is produced in one operation using a multiple-manifold die ring, to which for example three extruders are assigned, the meeting of the different components in the die ring taking place in a controlled manner. The partial colouring is carried out during this operation, the partial colouring being an element of the coextrusion. Polyolefin, which has an increased affinity to the base material, rubber, is preferably used. <IMAGE> |
