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 characterized 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 ) cannot be cut and resealed after installation, without leaving traces on the object to be sealed. |
