Abstract: The invention relates to a method for producing extruded profiled elements (3) from an elastomer material. In said method, the extruded profiled element (3) is formed from the elastomer material in a first step, the extruded profiled element (3) is entirely or partly surrounded by a thermoplastic material, the elastomer material that is surrounded by the thermoplastic material is cured, and the thermoplastic material is finally removed again once the elastomer material has been cured.

Abstract: The invention relates to a wiper blade (10) with a wiper strip (14) made of elastic material and having a wiper strip head (20) and a wiper lip (26) which can be placed on a window (22) to be wiped, wherein the wiper lip (26) is designed as a wedge-shaped extension (24) of the wiper strip head (20) and has a point angle (42) of between 60 degrees and 150 degrees, said point angle leading into a contact surface (44) having a radius (46) of smaller than 100 micrometers, and also to a method for the production of said wiper blade.

Abstract: A process for producing a strand-like extrudate (5) composed of a rubber material which is vulcanized after extrusion, in which the vulcanization is carried out in a bath (7) by means of heat treatment medium (9) present therein. The strand-like extrudate (5) is transported through the heat treatment medium (9) in an essentially vertical direction. An apparatus for carrying out the process, in which the bath (7) is configured in the form of a closed channel which has openings for entry and exit of the strand-like extrudate (5) and is arranged so that the strand-like extrudate (5) can be conveyed through it in an essentially vertical direction.

Abstract: A wiper blade for cleaning motor vehicle windows includes a wiper strip (12) which is held by a support bracket system (10) and is encompassed by a laterally closed protective profile (14, 22, 24). The protective profile (14, 22) is closed in the longitudinal direction (38, 40) on at least one end by a cover (16, 18, 20), which can be used to open and close the protective profile (14, 22).

Abstract: A wiper blade is proposed, which has a head piece made of a diene-type rubber and a flexing piece and wedge made of chloroprene rubber.

Abstract: A wiper blade for cleaning motor vehicle windows has a wiper strip (12) which is held by a support bracket system (10) and is encompassed by a protective profile (14, 58) to which a wiper element (16, 18, 20, 22) is fastened on the side oriented toward the window. The protective profile (14, 58) is comprised of an elastic material and has the capacity to be largely adapted to curvatures of the window by means of elastic deformation.

Abstract: The invention relates to a wiper blade having a head (1) for fastening in the wiper holder bracket, a tilting rib (2), and a lip (3). It is characterized in that the head (1) comprises a stiff polymer, hardened by halogenation, with a Shore A hardness of 60 to 85; the tilting rib (2) comprises a comparatively soft, elastic polymer that is not hardenable or not substantially hardenable by halogenation, with a Shore A hardness of 50 to 75; and the lip (3) comprises a polymer hardenable by halogenation having a Shore A hardness of 60 to 85. The Shore A hardness of the polymer comprising the tilting rib (2) is less expediently by at least two units than the Shore A hardness of the polymer or polymers that form the head (1) and the lip (3).
