Description
Technical field
The present invention relates to a kind of method that tire layer-stepping is repaired, belongs to tyre repair technical field.
Background technology
In tire production process, often there are some tires because manufacture reason causes local flaw, such as some bad symptom：Tire
Face shoulder bubble, tyre surface pressure thing etc..By excavating bad position sizing material, refilling sizing material post-cure can place under repair, with
When do not affect product quality, reduce factory's loss.But some flaw position is due in sizing materials such as tire tread shoulders
Thicker position, produces at bad symptom often relatively deeply, sizing material surface easily occurs and produce over cure in secondary sulfurizing course, and
There is under cure situation in the inside.Often depth is deeper, and filler gum is more, and repairing difficulty is bigger, slightly may cause accidentally
Repair failure.
