The invention belongs to the field of tire component production, and particularly relates to an air-impervious liner contour roll and an air-impervious liner. The contour roll comprises a middle cylinder, and a first side slope transition trapezoidal column, a second side slope transition trapezoidal column and a side cylinder are symmetrically, coaxially and sequentially arranged on the two sidesof the middle cylinder. The diameter of the cross section of the contour roll is transitionally increased from the middle cylinder to the side cylinder through the first side slope transition trapezoidal column and the second side slope transition trapezoidal column in sequence. According to the contour roll, even distribution of air-imperious liner materials at all the points of a tire is achieved, an air holding phenomenon of the end point of the air-imperious liner is avoided, and the generated problems of seam allowance bubbles are reduced.
本发明属于涉及轮胎部件生产领域,具体为一种气密层型辊及气密层,所述型辊包括中间圆柱体,中间柱体两侧对称并同轴依次设置有第一边部斜坡过渡梯形柱、第二边部斜坡过渡梯形柱以及边部圆柱体,型辊的横截面的直径从中间圆柱体到边部圆柱体依次通过第一边部斜坡过渡梯形柱、第二边部斜坡过渡梯形柱过渡增加。本发明型辊、实现轮胎各点气密层材料的均匀分布,避免气密层端点出现窝气现象,减少子口气泡问题的发生。
