Embodiment Construction
[0010] A method for repairing exposed lines in a tubeless finished tire, comprising the following steps: First, subsidize the parts of the finished tire that need to be repaired due to the exposed lines in the tire, the subsidized film is the same as the sealant used in the finished tire, and the main components are Masterbatch, sulfur, accelerator DM, accelerator TMTD; secondly, using the water tire working cylinder outer cylinder of the waste LDK tire air setting machine, the capsule is inserted into the cylinder outer cylinder as a whole, and the capsule is filled with air at the same time The central mechanism of the setting machine is lowered, and the capsule is smoothly pulled into the cavity of the finished tire; then, the finished tire is put back into the vulcanization tank and vulcanized by hot water under internal pressure, so that the pockmarked effect of the repaired part in the tire can reach the effect of a normal finished tire. The internal pressure hot water vu...

The invention relates to a tyre cavity thread exposure repairing method for a tubeless finished product cover tyre. The method includes: a first step of pasting an adhesive patch to the position needed to be repaired because of tyre cavity thread exposure of the finished product cover tyre; a second step of, by utilization of an outer cylinder of a curing bag working cylinder of a tyre air forming machine, nesting a whole capsule into the outer cylinder, feeding air into the capsule and allowing a capsule forming machine center mechanism to drop, so that the capsule is pulled into the tyre cavity of the cover tyre; and a third step of putting the finished product cover tyre back into a vulcanizer, and vulcanizing by utilization of internal pressure hot water, so that the pitted surface of the repairing position achieves an effect of a normal finished product cover tyre. According to the method, the capsule is inserted back into the tyre cavity of the cover tyre, put back into the vulcanizer, and vulcanized by utilization of the internal pressure hot water, thus overcoming difficulties in secondary reset of the capsule returning to the cavity of the cover tyre, easy cover tyre trademark double images, easy font double images, and the like, and achieving small contrast of the pitted surface effects of the tyre cavity defect repairing position with effects of positions around, good pitted surface effects and air exhausting thread effects, and other effects acceptable by a user.
Description
technical field [0001] The invention belongs to the technical field of tire processing, in particular to a method for repairing finished tires. Background technique [0002] For a long time, bias-ply finished tires have been repaired by subsidized film electric heating or returning to the vulcanization tank for vulcanization and grinding with polishing tools. In recent years, in order to increase the air conductivity of water tires, all water tire models have been treated with pockmarks; in the past two years, the production of bladder shaped and vulcanized engineering tires has increased rapidly, and the surface of the bladders is all pockmarked. Existing repair techniques cannot achieve pitted surface defects, and the appearance and visual difference between repaired defective parts and normal parts is very large, which is difficult for customers to accept, resulting in a large number of engineering giant tires being unsalable. [0003] We have tried the following repair ...
