And the thickness of the edge part is reduced by one layer, so that smooth transition of a ring part material can be effectively achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a steel wire bead wrapping cloth for a full-steel tire load-bearing structure. Background Art

[0002] There are two types of nylon wrapping: one is two-side wrapping; the other is single-side overlap.

[0003] The performance of the tire bead of the load-bearing products in the existing technology needs to be improved. The wire bead wrapping in the existing technology cannot well protect the wire end points, reduce stress and heat generation, and the wire wrapping bonding form does not meet the construction performance requirements. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the utility model provides a steel wire bead wrapping cloth for a full steel tire load-bearing structure to solve the above technical problems.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wire grommet wrapping for a full steel tire load-bearing structure, comprising a wire wrapping, wherein two mutually symmetrical first films are arranged on the upper surface of the wire wrapping, and a second film is overlapped and bonded to the bottom of the wire wrapping.

[0008] Preferably, one end of the second film extends in a direction away from the wire cloth.

[0009] Preferably, the steel wire cloth needs to be cut by a small-angle cutting device.

[0010] Preferably, the two first films are laid flat along two sides of the wire cloth.

[0011] Compared with the prior art, the present invention provides a steel wire bead wrapping for a full steel tire load-bearing structure, which has the following beneficial effects:

[0012] 1. The utility model increases the contact area of ​​the films between the steel wire cloth and the tire body by laying a first film flat along both sides of the upper surface of the cut steel wire cloth and laminating a second film on the lower surface of the steel wire cloth before the steel wire cloth is curled, thereby effectively reducing heat generation. The second film overlapped on the back can well protect the inner end point of the steel wire cloth, thereby effectively reducing internal cracks in the tire. When the steel wire cloth is laid flat, it is conducive to the discharge of gas during the molding process and effectively reduces the generation of bubbles at the bead of the tire after molding. Compared with the U-wrapped form on both sides in the prior art, the thickness of the edge is reduced by one layer, which can effectively ensure a smooth transition of the bead material.
