<p>The profile has a rubber profile (1) provided with continuous closed hollow space (4) at the interior of the rubber profile. The hollow space is associated with atmosphere via a return valve (2), so that air at the hollow space is exhausted, and the rubber profile is pretensioned at cross-section. The hollow space is filled with the air during opening of the valve, so that the clamping profile swells elasticity of the rubber profile using force. The profile is accommodated in two U-profiles (5, 6), which are pulled together. Clamping surfaces of the rubber profile are provided with a spring.</p> |
