Strength position for ultra high performance pneumatic tires in radial construction, in particular for the production of tyre carcasses, as well as a method for the construction of the strength position on a tire building drum

摘要

The invention relates to a strength position for ultra high performance pneumatic tires in radial construction, in particular for the production of tyre carcasses, wherein the strength layer of a plurality of successively to a web of material strength layers arranged sections, which are transverse to the longitudinal direction, are embedded in rubber reinforcement elements, as well as a method for the construction of the strength position on a tire building drum. It is the object of the invention to provide a strength position, which meets the requirements with respect to a carcass in an ultra high performance - tire is met, and with the manufacturing process of the tire of a carcass structure is substantially simplified and can be kostenvergünstigt. The production should tyre building drums can be carried out in a conventional. The object is achieved in that the reinforcement elements (2, 7) consist of rayon, that two adjacent strength layers sections (6a, 6b) at their mutually facing edge regions that are arranged in overlapping manner and at least on one (transversely -) edge of the overlapping strength layers sections a hem (4a, 4b) is formed, in which the reinforcement elements (7) a smaller diameter than the reinforcement elements (2) have outside of the hem.
