1. Arrange the data in the order of volume, volume content, file and reference table, and then punch holes in the file with a punch.
2. The punched document can be clamped by dovetail clamp, which makes the document not easy to be scattered and convenient for threading and binding.
3. Put the binding needle on the cotton thread to ensure that it is a single strand. Pass through the middle hole on the back of the file.
4. After passing through the front, you can choose to pass through the upper hole or the lower hole to see your personal habits.
5. Pass the line through the back of the file again, then lead it from the hole in the middle of the front to the back, and then lead it from another hole to the front.
6. Finally, tie a fast knot at the end of the line, cut off the redundant line, ensure the rope is tight, and prevent the file from loosening. After completing the above steps, the file will be bound.
