[0002] Paper cutting refers to the process of cutting paper into the required size and shape. This process may involve various types of paper, such as manuscript paper, cardboard, wrapping paper, etc. First, you need to accurately measure and mark the size and shape of the paper to be cut. You can use a ruler, a scale and a pencil to mark to ensure the accuracy of the cutting. Generally, a whole stack of paper is cut at the same time. After the measured paper is moved to the cutting table, the stacked paper may be displaced due to the movement, causing the edges around it to become uneven. Therefore, one end of the paper needs to be adjusted to restore the stacked paper to a flush state, and manual adjustment is more laborious. Utility Model Content
