A optimum model is proposed for the split plate design of the labelling machine using self-adhesive labeds. the results shows that the curvity radius of split plate edge is of a optimum value that the driving work will be minimal.

• 探讨了用解析的方法解决压敏标签贴标签机的剥离刀口的优化设计问题，分别提出了剥离刀口处的张力功、摩擦功、弹塑性变形功和剥离功的计算模型，并对结果进行了讨论，结果表明，剥离刀口的曲率半径存在一个最优值，此值分别与纸带预张力、压敏胶的特性、标签的瞬时剥离宽度、底纸带特性等有关。
