ABSTRACT:
A wiping strip for a motor vehicle screen wiper is in the form of a profiled element of vulcanised material consisting of rubber or an elastomeric material, having a surface layer for reducing the coefficient of friction between the wiping strip and a glass surface to be wiped. The surface layer is formed by immersion of the profiled element in a solution, or by exposing the profiled element to the solution in atomised form. The solution consists of a solvent with a powder, such as graphite, dispersed in it. The step of forming the surface layer is carried out during the step of vulcanising the material of the profiled element.
