Abstract: An elevator system with a car or platform to transport passengers and/or goods as well as with a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material, containing a first exterior surface, and with at least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—that is embedded in the first layer of the suspension element. A manufacturing procedure for one of the suspension elements is provided.

Abstract: There is provided a steel cord including a plurality of untwisted core filaments of steel aligned in parallel, and a layer of sheath filaments of steel twisted around the core filaments so as to be unevenly distributed around the core filaments, wherein interstices between the filaments are maintained during vulcanization thereby achieving improved rubber penetration (sufficiently adhering rubber to the core filaments). Since the cross sectional length of the steel cord 10 is greater than the minimum cross sectional length, interstices A are maintained between sheath filaments 14 under the tension and pressure p of the surrounding rubber 16 applied to the steel cord 10 during vulcanization. Rubber 16 penetrates into the steel cord 10 through the interstices A, and sufficiently adhere to core filaments 12 to achieve high rubber penetration.

Abstract: A process for producing a steel cord for pneumatic tyres with a bunch of wires, the core of which consists of wire filaments (10) arranged in a bunch parallel and adjacent to one another. There are advantageously at least three wire filaments (10, 20), where at least two wire filaments (10) are spirally wound as filaments (10) forming a core (60) and run parallel and beside each other and at least one wire filament is spirally wound around the two core filaments (10) as the wrapping wire (20). According to the invention, the spiral deformation of the wire filaments (10) is obtained by false twisters (40). This spiral deformation of the wire filaments (10) especially prevents migration of the filaments from the cord composite. It is an advantage if residual torsional stresses between the core filaments and in connection with the restoring forces of the wrapping wire are relieved. The steel cord also advantageously has a flattened, especially oval, shape.
