Method for preparing tire through wavy zero belt

A wave-shaped and belt-shaped technology, which is applied to the reinforcement layer of pneumatic tires, tire parts, tires, etc., can solve the problems of large tension difference between the middle and side parts of the pneumatic belt layer, easy to produce abnormal wear, and high material cost. To achieve uniform distribution in the circumferential direction, reduce cost and tire weight, and achieve the effect of overall flatness

Embodiment Construction

[0021] A belt structure of an inflatable all-steel radial tire, the belt structure is composed of a No. 1 belt 11, a No. 2 belt 12, a No. 3 belt 13, a wave-shaped zero-degree belt 14, a shoulder Pad glue 15 forms.

[0022] A method for preparing a tire using a wave-shaped zero-degree belt, the specific steps of which are:

[0023] (1) Preparation of wavy belt strips: design a special extrusion die, and extrude wavy belt strips with a lower density than conventional zero-degree belt layers;

[0024] (2) Coiling of wavy belt strips: the extruded wavy zero-degree belt layer is wrapped with a plastic film with good fresh-keeping effect and coiled;

[0025] (3) Belt layer bonding: according to the normal belt structure method, the first, second, and third layer of belt layers are centered;

[0026] (4) Wave-shaped zero-degree belt winding: wind the first layer of wave-shaped belt at the corresponding belt layer position, and use the winding machine to form an angle of 0°-2° with ...

Abstract

The invention relates to the technical field of tires, in particular to a method for preparing a tire through a wavy zero belt. A belt ply structure is composed of a first belt ply, a second belt ply, a third belt play, the wavy zero belt and tire shoulder pad rubber. The method relates to the belt ply structure for an all-steel radial tire, the density of a zero belt ply is decreased by half, and the zero belt ply is wound by two circles; and the upper layer and the lower layer are arranged in a staggered mode, so that the effect that only one bet ply exists actually is achieved. Since each steel cord is wound by two circles, the strength of joints is guaranteed. The original zero belt ply is restrained and hooped tightly, the cost and the weight of the tire can be reduced, more importantly, the bet plies are smooth and uniform in thickness on the whole, and the high-speed performance and abrasion resistance of the tire can be greatly improved through the belt ply structure; and meanwhile, framework materials are distributed more evenly in the circumferential direction, and thus the uniformity and comfort of the tire can be improved.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a method for preparing tires using a wave-shaped zero-degree belt. Background technique [0002] In the existing tire structure, the conventional 3+0 belt structure is adopted; the belt layer I, the belt layer II, and the belt layer III are sequentially wound with two layers of the same zero-degree belt layer 4, and the shoulder pad rubber 5 placed under the belt. The zero-degree belt layer adopts two layers of the same structure, and the material cost is high; the belt layer is thin in the middle and thick on both sides, and the tension difference between the middle part and the side part of the inflatable belt layer is large, and the stress is concentrated, which is prone to abnormal wear and production during use. Shoulder empty due to excessive heat. Contents of the invention [0003] In view of the above problems, the present invention proposes a method for preparing tires...
