[0002] Tarpaulin is a waterproof material with high strength, good toughness and softness. It is often used as canvas, polyester with polyurethane coating or made into polyethylene plastic. Tarpaulin usually has strong eyelets at the corners or edges to facilitate rope binding, hanging or covering. Tarpaulin is usually divided into two categories: coarse tarpaulin and fine tarpaulin. Coarse tarpaulin, also known as tarpaulin cover, is strong and fold-resistant, with good waterproof performance. It is used for automobile transportation and open-air warehouse covering and outdoor tents; the warp and weft yarns of fine tarpaulin are used to make labor protection clothing and supplies.

[0003] At present, the produced tarpaulin is in a regular rectangular shape, and then it needs to be cut and processed into the required shape. During the cutting process, the tarpaulin is laid flat on a cutting table and cut by a cloth cutting machine. However, when cutting irregular shapes, large cloth cutting machines cannot meet the needs. It is necessary to manually hold the knife and draw the cutting line along the tarpaulin for cutting. The tarpaulin needs to be flattened and pressed before cutting, which is slow, inefficient and inconvenient to use. Utility Model Content
