摘　　要：带束层是子午线轮胎的重要部件．是子午线轮胎在高速行驶时主要受力部位，其位于胎面与胎体之间．由2-4层交叉的钢丝帘布组成。最靠近胎体一层称为过渡层，帘线角度为55°～65°，主要作用是使由径向排列的胎体帘线角度过渡到接近周向排列的小角度带束层，这样可以减小层间的剪切力，避免带束层与胎体帘布层之间的脱层；第2层及以上是带束层结构中主要承受应力的帘布层，称为工作层。工作层帘线方向与轮胎行驶方向成小角度，The quality of belt directly impacts on the wear-resistant, traction, handing, safety and many other properties of radial tire. To ensure the belt＇s building quality, improving product performance and achieving device optimization, in this article, according to the adjustment of width, height and centrality of expanding and shrinking guide frame of the former auxiliary drum, which is the important equipment affecting belt quality, it makes good effect in improving belt quality.
