The paper-cut handicrafts are diverse in shape, ever-changing, and highly valued in art appreciation. They are very suitable for children's enlightenment education. Such paper-cut patterns have been widely used in children's education abroad; however, traditional paper-cutting methods are used to make such paper-cut patterns. , the pattern consistency is poor, not suitable for mass production.

For this reason, a method suitable for mass production is adopted, that is, a pattern cutter for processing a cut pattern, which is a thin blade with a sharp edge that is bent into a pattern to be processed and embedded in the flat plate. Fixed, and then use this pattern cutter to press cut paper or similar flat sheet material, the cut material forms the same single art pattern as the thin blade pattern, which is the desired product, such as to produce different shapes of products, It is only necessary to change the pattern cutter of different shapes; for example, the "one paper cutter" of the Chinese invention patent No. 01209608. 3 belongs to the pattern cutter, and the pattern cutter can realize large The effect of cutting the paper pattern in batches, but there are also obvious disadvantages: (1) Since the thin blade with the same contour of the pattern is difficult to process and takes a long time, the pattern cutter is expensive to manufacture; Since the pattern cutter must be used on a flat plate made of a non-rigid material having a certain hardness (such as plastic material PP, PC, ABS, AS, nylon 66, etc.), It ensures that the normal cutting of the flat sheet material reduces the damage to the blade edge of the pattern cutter, so the operation requirements are high and the use is not convenient; (3) The paper pattern formed by the pattern cutter can only be formed. It is a flat sheet-like flat pattern. It has no three-dimensional effect and is not vivid enough to express the layering of the pattern. A paper press disclosed in Chinese Patent No. 200620058230.4 can only suppress a three-dimensional artistic paper product, that is, there is only one layer of the convex piece for pressing the three-dimensional pattern on the mold, and the pressed pattern is not rich in layers, three-dimensional Poor.
