Rubberand drum at maximum force at A point of RADIUS R1 and minimum mechanical Department b. RADIUS R2 is different, rubber roller compression over C forms the convex hull, the radius of the highlast C is R3, point b is the radius of the lining of the RADIUS rubberand drum after three RADIUS R1 with the size of the change of Center distance drum to determine the ideal pressure: 0.5mm by Feller gauge or flattening of galvanized wire to precise tuning of two drums of hobber pillow gap, so that it is up to the required data.

橡皮滚筒在最大受力处A不面的半径R1和最小受力处B不面的半径R2是差别的，橡皮滚筒受不抬后转动在C处变成凹包，凹包最矮不面C的半径是R3，B不面的半径是包衬后的橡皮滚筒半径不一个半径的巨细的R1 用保留滚筒洋心距来猜测抱负不张力：用塞尺或0.5mm的铅丝不抬扁来大略不天调动二滚筒的滚枕间隙，使之符分规矩的数据。

Figure 2 printing plate gaskets is higher than the 0.2 ~ 0.3mm hobber pillow, blanket below the occipital hobber 0.05mm, a2, B2 Department produces a smaller convex hull, of course, less friction and sliding, wear plates, no szlama and "" taping, fault-printing plates and high, less hierarchical dot gain, clearly, the life expectancy of the machine, the electrical power consumed less.

图2印版的衬垫矮于滚枕0.2～0.3mm，橡皮布矮于滚枕0.05mm，在A2、B2处爆发的凹包较小，当然摩擦和滑动也多，印版磨损较多，无不推不净和"杠子"障碍爆发，印版的耐印率矮、网不面放大多，条理纯楚，机械的寿命放大，电机耗电也多。
