The strip comprises flanges (28) extending from a core (24), which when the strip is inserted in the strip track (26) as the result of friction against the strip track walls is folded backwards, when viewed in the direction of insertion. Through the effect of resistance against the strip track walls the withdrawal of the strip out of the track is counteracted. - The flanges are formed as rounded bodies with a shaft end, with which they are fastened to the strip core. The bodies after insertion in the strip track, under deformation, execute a rolling function between the strip core and the strip track wall with the strip movement relative to the track, which produces the resistance effect. The core is band-shaped with flanges extending from the band side(s). - (Dwg.13/13) |
