The invention is applicable to the technical field of tires, and provides a method for addressing the inner crack of a tire seam allowance. The method comprises the steps of selecting a tire blank with a seam allowance internal crack disease as an experimental object; detecting the position range of the tire blank problem on the experimental object; the tire blank problem at least comprising the seam allowance internal crack disease and a tire blank seam allowance inner side fall greater than a specified value; attaching a rubber sheet to the lining of the tire blank without the tire blank problem, wherein the attaching position of the rubber sheet is determined according to the position range of the tire blank problem on the experimental object. Compared with the prior art, the phenomenonthat the tire blank without the tire blank problem generates the tire blank problem at the same part is effectively avoided, the attached rubber sheet can effectively protect the seam allowance endpoint of the tire and reduce the fall of a turn-up endpoint on the inner side of a small-specification seam allowance, so that the transition is gentle, and the safety coefficient of the small specification is increased; and therefore, the quality of the tire is improved, the number of maintenance products and waste and inferior-quality products is reduced, and cost and manpower are saved.
本发明适用于轮胎技术领域,提供了一种用于解决轮胎子口内裂的方法,包括以下步骤:选取具有子口内裂病象的胎胚作为实验对象;检测实验对象上出现胎胚问题的位置范围;所述胎胚问题至少包括子口内裂病象和胎胚子口内侧落差大于指定值;在未出现胎胚问题的胎胚的内衬上贴附胶片,胶片的贴附位置根据实验对象上出现胎胚问题的位置范围确定。与现有技术相比,本发明有效避免了未出现胎胚问题的胎胚会在同一部位出现胎胚问题的现象,所贴附的胶片能够有效保护轮胎的子口端点,降低小规格子口内侧反包端点处落差,使其过渡平缓,增加了小规格的安全系数,使得轮胎的质量得到提升,减少维修品和废次品的数量,节约了成本和人力。
