Use 2m paper, the specified book back should be flat, solid, no foaming, book thickness 8-20mm147×2(0 32 For the semi-automatic type, the rated cutting intensity of B5% is 5.3. According to the provisions of 5.3.1, cutting is carried out, and the cutting quality is checked according to the method in the appendix (the appendix of the standard), and the cutting accuracy is improved by random rotation. The cutting accuracy meets the requirements of 4.2. If the manufacturer has the conditions, the machine noise is measured by ordinary sound level. The height of the measuring point is (machine height + 1) / 2]. The four measuring points are 1m from the symmetrical center line of the machine. The machine noise is the calculated average of the sound values of the four measuring points. The point meets the requirements of 4.4. 5.5 After the rotation test, the bearing temperature is measured with a point thermometer, and the temperature rise is calculated to meet the requirements of 5. 5. (Under static conditions, the ground pressure is measured with a force measuring device, which shall meet the relevant requirements of Table 1. 5.
