[0002] Glass fiber cloth is a high-strength, high-temperature-resistant, and chemical-resistant material, commonly used in aerospace, automobile manufacturing, construction engineering, and other fields. In the production process of glass fiber cloth, in order to improve the cutting efficiency of glass fiber cloth, multiple layers of glass fiber cloth are generally cut together, but this will cause the glass fiber cloth between each layer to shift. Welding equipment is needed to combine multiple layers of glass fiber cloth together so that each layer of glass fiber cloth is relatively fixed for easy cutting.
