Method for manufacturing tire component member

The invention relates to a method for manufacturing a tire component member. Test conditions including the number of windings of winding a ribbon rubber around a forming drum and a feed pitch for moving the ribbon rubber in an axial direction of the forming drum for each rotation of the forming drum are set, and a test sample is prepared under the test conditions. A thickness distribution in a width direction of the prepared test sample is measured, and the thickness distribution in the measured width direction is compared with the target shape to specify the ribbon rubber located at a portionin which a thickness deviation amount exceeds a predetermined range. Then, the feed pitch of the specified ribbon rubber is changed to prepare the tire component member. 本发明涉及一种轮胎构成部件的制造方法。设定测试条件，并按照所述测试条件制作测试样本，其中所述测试条件包含将所述条带橡胶卷绕于成型鼓的卷绕次数和所述成型鼓每旋转一周时使所述条带橡胶沿所述成型鼓的轴向移动的输送间距。针对所制作出的测试样本测量宽度方向上的厚度分布，并对测量出的宽度方向上的厚度分布与目标形状进行比较，确定位于厚度的偏差量超出给定范围的部位的条带橡胶。然后，变更所确定的条带橡胶的输送间距来制作轮胎构成部件。
