Twisting method and installation with tension control for the production of reinforcing cords for tires

The method for producing a wire element by interlacing at least a first strand and a second strand, during which strand tension control is effected by includes defining an assembly tension set point representative of a state of longitudinal tension to be obtained in the first strand when said first strand reaches the assembly point. The method also includes measuring the actual assembly tension applied in the first strand, said measurement being taken at a first tension measurement point located along the first strand and upstream of the assembly point. The method proceeds with operating a tension regulating member such as a capstan, which acts on the first strand upstream of the assembly point such as to cause the actual assembly tension within said first strand to converge automatically towards the assembly tension set point.

BRAIDING, WINDING OR SPIRALLING MACHINE AND METHOD FOR OPERATING SAME

The invention relates to a method for operating a braiding, winding or spiraling machine for braiding around, wrapping around or spiraling around a strand-like material, in particular a cable, with at least one elongate material strand formed from at least one elongate material fibre, in particular from at least one wire. In the method, a diameter of the strand-like material is measured and a feed rate of the strand-like material and/or a rotational speed at which the at least one elongate material strand moves about the longitudinal axis of the strand-like material is controlled by open-loop or closed-loop control depending on said diameter measured. A predefined degree of coverage of the strand-like material by the at least one elongate material strand can be kept substantially constant by means of an open-loop or closed-loop control of the relative feed rate of the strand-like material depending on the diameter measured.

SYSTEMS AND METHODS FOR FORMING A CABLE

Systems and methods are provided for forming a cable. In one embodiment, a system for forming a cable comprises a non-driven roll station having a plurality of rolls for forming a shape of one or more strands associated with a first layer of the cable. Movement of the plurality of rolls of the non-driven roll station occurs passively during travel of the one or more strands associated with the first layer of the cable. The system further comprises a driven roll station having a plurality of rolls for forming a shape of one or more strands associated with a second layer of the cable. The plurality of rolls of the driven roll station are actively driven to effect movement and speed of the one or more strands associated with the second layer of the cable.
