Title
(EN) Manufacturing method of run-flat tire
(ZH) 缺气保用轮胎的制造方法
Abstract
(EN)
A method of manufacturing a run-flat tire capable of manufacturing a run-flat tire with excellent uniformity due to its less occurrence of eccentricity than in conventional methods by simple facility and steps. The method comprises a step for disposing an inner liner rubber (19), reinforcement rubber members (18) reinforcing side wall parts on both sides, and a carcass ply (14) at the prescribed outer peripheral positions of a molding drum, a step for disposing a pair of first beads (1a) and bead fillers (12) and toroidally deforming the inside of the first bead (1a), a step for curling up and stamping the end part (14b) of the carcass ply (14), a step for stamping rubber members (13a) and (13b) forming annular swelled parts on the sides of the bead filler (12) of a toroidal formed product, and a step for forming second beads (1b) by spirally stamping cords (BW) on the formed product while rotating the formed product after that stamping about the axis thereof.

本发明提供一种缺气保用轮胎的制造方法,由于与以往方法相比,该制造方法难以产生偏心,因此可以借助简单的设备及工序制造出均匀性良好的缺气保用轮胎。该制造方法包括以下工序:在成型鼓外周规定位置分别配设气密层橡胶(19)、帘布层(14)和用于加强两侧胎侧部的加强橡胶构件(18);配设一对第1胎圈(1a)及填充胶条(12),使比该第1胎圈(1a)靠内侧的部分变形为环状;卷起上述帘布层(14)的端部(14b)并对其进行粘贴;在环状成形物的上述填充胶条(12)的侧方粘贴构成环状鼓出部的橡胶构件(13a、13b);一边使粘贴后的成形物绕轴心旋转、一边将帘线(BW)粘贴成螺旋状而形成第2胎圈(1b)。
