[0002] For a long time, when sewing fabrics for umbrellas, awning tents, the fabric is in the shape of an equilateral triangle with a 60-degree angle during the cutting process. If flat cutting is used during fabric pulling, about 60 cm of corner edges will be formed at both ends of the fabric and cannot be used normally, resulting in a high waste of factory raw materials.

[0003] To solve the above problems, this application designs an adjustable-angle fabric pulling machine. The factory can adjust the required diagonal cutting angle according to the angle of the cut pieces, so that both ends of the fabric can be used normally and the loss of the fabric can be reduced.
