分析了折页模式的描述格式，根据印张折痕的位置关系及变向特性对折页模式进行了分解，将复杂折页模式分解为了一系列平行折的顺次组合。结合平行折研究了折页模式与折页单元之间的组配关系，归纳了折页模式与折页单元的组配规则。以JDF定义的85种常用折页模式为参照，提出了一种基于折页模式与折页单元组配的折页机工作效能分析方法。

The describing format of the folding pattern was analyzed. The folding pattern was decomposed according to the relative location relationship and direction changing character of folds, on which the complicated folding pattern was decomposed as a combination of a series of ordinal parallel folding patterns. Combined with the parallel folding patterns, the matching relationships between folding patterns and folding units were studied, and the matching rules of folding patterns and folding units were induced. Using the 85 folding patterns defined by JDF as reference, a working ability analysis method of folding machine based on the matching relationship between folding pattern and folding unit was put forward.
