正确的安装方法可使弧形辊达到最佳的展
平效果（Fig1），基材通过弧形辊的凹面，通
常要有较长的导入距离 -A- 和较短的导出距离
-E- ，距离 -A- 通常是距离 -E– 的2 倍左右，尺
寸 -E– 要接近2倍或2.5倍弧形辊的直径。
提示：安装弧形辊时，请确保弯辊和基材是对
齐和垂直水平的（Fig2）
弧形辊包角
包角W根据不同的卷材要进行适时地调整，下面根据不同的卷材推荐的包角角度。
纸行业： 成形网 25-20°湿毛毡 30-60°纸/板 15-30°。
薄膜和锡箔：PA和PP膜 1-6微米 60-90°、 8-20微米45-60°
20微米以上45°、静电膜 15-20°。
纺织行业： 普通织物 45-60° 延展布 60-90°。
Optimum effect will be achieved by mounting the spreader roll as shown in Diagram 1(Fig.1).
Long entry distance –A– short output distance –E– The material web should always pass over the con-cave side of the Bowed Roller.
Dimension “A” should always be twice the exit span “E”. Dimension “E” should be approximately two and a half times of the Bowed Roller.
Note: When install the Bowed Roller please ensure that it is aligned both vertically and horizontally onto the material web As shown in diagram1(Fig2)
