Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] refer to figure 1 , a method for stitching and repairing radial tire flaws, comprising the following steps:

[0037] 1. Observe whether the injured part of the tire is within the repairable range:

[0038] The upper part of the wound should not exceed the tire shoulder, the lower part should not be close to the tire opening, the overall width of the wound should not exceed 55mm, and the maximum length and maximum width cannot exist at the same time, that is, it can be repaired. There are generally three types of wounds that can be repaired:

[0039] 1. Only one wound.

[0040] 2. Two wounds separated upper and lower.

[0041] 3. The side wall is injured and the internal injury is not leaking but bulging.

[0042] Second, the plastic treatment of the wound:

[0043] 1. Use a curved rubber digging knife to dig in a square or a rectan...

Abstract

The invention provides a method for sewing mechanical damage of a radial ply tire, which comprises the following steps: a. digging out a rectangular opening taking the biggest edge of the original damage as the side; b. starting sewing from one angle of the rectangular opening; c. passing the thread end to the inner side of the tire from the rectangular opening, pulling out the thread at the edge of the rectangular opening opposite to the position of starting sewing by a crochet hook, passing the thread end to the inner side of the tire from the rectangular opening again, pulling out the thread at the edge of the rectangular opening opposite to the position of starting sewing by the crochet hook again, repeating the steps until the rectangular opening is sewed, wherein the threads are arranged vertically along the direction from the inner side of the tire to the outer edge of the tire, and two adjacent needle holes at the same side are not in different horizontal lines. The repairing method comprises: polishing performed between the steps a and b; performing the rubber heat curing treatment after the step of c; and performing cold curing treatment and appearance treatment on a patch. The tire repaired by the method is not broken.

Description

technical field [0001] The invention relates to the technical field of tire repair, in particular to a method for sewing radial tire flaws and a repair method. Background technique [0002] Due to collisions and other reasons, the tires have flaws, and most of them cannot be repaired and can only be scrapped. Many of these scrapped tires are tires with a short mileage, so it is a pity and unbearable for us to discard them as garbage and waste products. This is not only a loss for the majority of car owners, but also an economic waste to the country and pollution to the environment. [0003] For the repair technology of radial tire sidewall flaws, most tire shops are currently unable to repair them, and only a few shops can repair them. The methods generally include the following: [0004] 1. The tires with small wounds are not sutured, but are directly vulcanized by rubber, and then reinforced with corresponding larger patches to avoid or reduce bulges and improve safety. ...
