[0017] The beneficial effects of the present application are as follows:

[0018] Through the cross locking of the multi-layer woven tape structure (a, b, c, d layers) and the multi-layer heald control, the woven tape can effectively disperse the pressure when stressed, avoiding the bursting phenomenon caused by local stress concentration. The bottom and top surfaces of the woven tape have good bursting resistance, and the bursting value can reach more than 40 kg, significantly improving the safety and service life of the product.

[0019] The reasonable matching of the porous heald and the single-hole heald, combined with the threading sequence and the alternate locking edge technology, forms a firm connection between the layers of the woven tape, avoiding delamination or loose structure, further enhancing the tensile and bursting resistance of the woven tape. Through the design of the flower chain and the precise control of the heald, the bottom structure, surface structure and four-layer main structure of the woven tape are simultaneously woven and locked, ensuring the stability and clear hierarchy of the woven tape structure, meeting the process requirements of high-end products.

The arc-shaped cavity formed in the middle of the woven tape facilitates the embedding and fixing of the steel ring and other materials, improving the functionality and wearing stability.
