1. During the production of the paper slitter equipment, due to the lateral warpage of the steel sheet, the width dimension is poor. This is because the product cut in the lateral warping state is measured more than the setting value of the knife.
2. During the operation of the paper slitting machine, if there is a problem of lateral swing of the tool, it will result in poor dimensionality, such as the lateral swing of the tool and the difference in the outer diameter of the tool. Since the lateral swing value of the tool cannot be zero. Usually the lateral swing value of its load is about 0.03-0.05 mm. The reason is the accuracy error of the blade thickness, the inner diameter, the spacer sleeve width, and the warpage caused by the lateral stress when the thick plate is sheared.

3. Because of the production operation of the paper slitting machine, there are certain fitting errors in the spacer sleeve and the cutter. In general, the thickness accuracy of the spacer sleeve and the tool is 0.005. When the number of pieces is large with the knife, the cumulative error becomes large. This is due to poor upper tolerance setting. It should be noted that the width of the product cut by the paper slitter is always slightly lower than the tolerance of the product side of the knife. Therefore, it is necessary to predict the degree of this difference in advance. Refer to the dimensions of the spacer sleeve when the knife is placed on the side of the product. The cutting method used is also considered later. In comparison, if the paper slitter is straight-pulled, the tension of the coil will increase, the lateral warp will disappear, and the size will go down.
