立式平压模切机的主要作用是将纸板按要求完全切断和清晰压痕。由于纸板尺寸往往很大，要求机器两大平板平面度很高，平行度也很高。虽然设计与制造者努力按要求去做，但由于大平板衬板的平度、模切板的平度以及受力变形等因素，仍很难做到一次全部切断，要完全切断和压痕清晰 Vertical die-cutting machine’s main role is to press the cardboard completely cut off and clear indentation. Due to the large size of the cardboard, the plane requires two flatness of the machine is high, parallelism is also high. Although the design and manufacture of hard to do as required, but due to the flatness of flat-panel liner, the flatness of the die-cutting board and the force deformation and other factors, it is still very difficult to achieve a total cut, to completely cut off and indentation clear
