<p>The tongue material (2) is shaped, in a hot state, immediately after the extrusion thereof, preferably by means of a gear wheel acting upon the tongue material. The tongue material (4) is preferably longitudinally drawn after cooling below the solidification point thereof, with preferably a doubling in length. The final tongue profile (7) is thus achieved which displays a higher stiffness due to the stretching and may be adjusted to length or cut to length. The tongue (7), produced in the above manner, is finally mounted on the base body (8) of the drawn seal (1) by a spray application and forms the final drawn seal (1), together with the sealing body, also preferably mounted to the base body (8) by a spray application. The above is characterised not only by the good stability, but by the adjustable length of the tongue (7) and also a high security on manipulation. The final drawn seal (1) can not be cut and resealed after installation, without leaving traces on the object to be sealed.</p> |
