Description

Blastic sealing strip

The innovation is an elastic, rubber or the like. existing sealing strip with a U-shaped profile.

Sealing strips made of rubber have already become known which have a U-shaped profile in cross section. The legs of such seals have also been provided with a fine tooth-like profile on the inside in order to achieve a better seal, which has proven to be particularly advantageous when sealing glass panes in motor vehicle windows. However, it has been shown that for. sealing of cut edges gross plates, for example, such fine-profiled Dichtungsatreifen are not suitable or of plywood planks in wagon used.

The goal of the innovation is now, on the one hand, the cut edges of wood or the like. to protect against moisture binding and, on the other hand, unavoidable tolerances during installation, e.g. B. in the steel frame of freight cars, to be compensated by an elastic sealing strip. According to the innovation, it is proposed that the two legs of the U-profile be provided with expansion grooves on the inner and / or outer surface. The incompatible Werkatoii Guanii has the opportunity to do so during the installation
