1. During the production of the paper slitter machine, there is a problem of transverse warpage of the steel plate, which results in poor max-width='100%' width dimensions. This is because the measurement of the product cut in the state of transverse warpage is larger than the setting value of the knife.

2. In the process of paper slitter equipment, if there is a lateral swing of the tool, then it will lead to the generation of poor dimensions, such as the lateral swing of the tool and the outer diameter of the tool size is different and poor. As the tool lateral swing value can not be zero. Usually its load of lateral swing value of about 0.03-0.05mm. the reason is the knife thickness, inner diameter, spacer max-width='100%' width and other precision errors, thick board shear lateral stress generated by warping.

3. is due to the production of paper slitting machine equipment with the operation of the spacer sleeve, cutter, etc., there are some matching errors. Normally, the spacer, cutter and other thickness accuracy of 0.005. Matching knife when the number of pieces is larger, the cumulative error becomes larger. This is due to poor upper tolerance setting. It is important to know that the max-width='100%' width of the product cut by the paper slitter is always slightly lower than the product side dimensions of the matching knife tolerance state. Therefore, it is necessary to anticipate the extent of this lower tolerance in advance. This is used as a reference when determining the size of the knife time spacer on the product side. Finally, it is also necessary to take into account the shearing method used. In contrast, the paper slitter equipment using straight pull type shear, then the steel coil tension increases, lateral warping will disappear, the size will go down the difference.
