Abstract: A method and the device serve to supply a heating press with electrical energy. At least one fuel cell is used. In particular, the fuel cell is located in a tire heating press or in close proximity to the tire heating press.

Abstract: A handling device for tires having at least one extension arm, wherein the at least one extension arm is secured with a first extension arm pivot location to a receiving member in such a manner that a pivoting of the at least one extension arm relative to the receiving member is supported and the at least one extension arm has a second extension arm pivot location so that at least one gripping tool is coupled to the at least one extension arm. At least a second gripping tool is coupled to the second extension arm pivot location, and the at least two gripping tools can be pivoted relative to at least one extension arm pivot location. The invention further relates to a method for carrying out a loading and unloading cycle with tires of a tire vulcanization machine.

Abstract: A belt package for a pneumatic vehicle tire has at least two belt plies. The belt plies are built up in at least two sub-packages, which are automatically placed on a belt drum and automatically spliced independently of one another. The sub-packages are then joined together to form the complete belt package.

Abstract: A pneumatic tire for a vehicle has a casing that extends over the periphery of the tire, a belt that extends radially on the outside of the casing over the entire periphery of the tire and in an axial direction over at least the width of the pneumatic tire. The belt is made of one or several belt plies with rigid supports which are embodied diagonally in the direction of the periphery of the tire and are embedded in a parallel manner in the rubber or plastic material. A bandage extends radially on the outside of the belt over the periphery of the tire. One or several parallel reinforcement supports are wound about the external belt position which is constructed on the construction body in a helical or spiral-shape in the axial direction of the construction body which is oriented, substantially, in the direction of the periphery which is constructed on a pivotable, rotationally-symmetrical construction body which is radial to the outer belt position of the belt in order to produce the bandage.

Abstract: An apparatus and method are provided for the helical winding of an essentially band or strip-shaped reinforcing element onto at least one ply of a pneumatic tire blank. The apparatus includes a rotating tire or belt build-up drum, a winding wheel disposed upstream of the drum and connected with devices for applying tension to the reinforcing element, and sensors that detect the position of the reinforcing element on the winding wheel, and the tension applied to the reinforcing element, and convey these values to a control device. The winding wheel is connected with a motor for driving or slowing the winding wheel, whereby at least two tensioning and guide rollers are radially spaced relative to the winding wheel such that the reinforcing element, which is guided over the winding wheel, forms a defined looping angle.

Abstract: A pneumatic vehicle tire of radial construction, especially for automobiles, is provided. The tire has a profiled tread strip, a belt structure of at least two belt plies, bead regions having bead cores, and a carcass having load-carrying members of steel cord. In the tire the carcass forms a C-ply construction and contains steel cords of three or five steel filaments, which all have the same diameter of 0.12 to 0.1 5mm.

Abstract: A reinforcing cord for a belt ply or a carcass ply of a pneumatic vehicle tire is provided and comprises a core filament and four to six ply filaments. The core filament is comprised of an elastically or plastically deformable polymeric material, or is encased with such a material, which fills the space surrounded by the ply filaments and/or penetrates into the gaps between the ply filaments.
