For example, in the textile industry, laser cloth cutting machines are used to cut cloth. As the name suggests, cloth cutting is to cut or split one side or both sides of the cloth. Using a laser cloth cutting machine to cut the cloth during processing can make the edge of the cloth smooth and beautiful, and can also prevent the edge from curling.

[0003] However, currently when the cloth is placed on the laser cloth cutting machine for cutting, since some cloth is prone to warping and curling, it is necessary to manually flatten and fix the cloth, so as to reduce the occurrence of poor cutting effect, incomplete cutting and over-cutting caused by uneven cloth, which affect product quality. Manually flattening and fixing the cloth is time-consuming and labor-intensive, which affects the overall cutting efficiency of the cloth. Therefore, further improvements can be made.
