[0002] A weft straightener is a machine used to correct the weft threads. It is widely used in the textile industry. It can effectively correct the weft skew and weft arc produced during the production process of the fabric, thereby improving the quality of the fabric.

[0003] Due to the continuous radial stretching and the influence of various factors, the weft yarn of the fabric will be skewed and bent. This phenomenon is called weft skew. If the weft skew is not corrected in time, the pattern will be skewed, and the clothes will be deformed after being made into finished clothes, especially the striped or lattice pattern fabric and yarn-dyed fabric, the deformation will be more obvious, which will seriously affect the product quality. Therefore, weft straightening machines are often used to correct the weft skew of the cloth.

[0004] The cloth is unloaded after being straightened by the weft straightening machine. The unloaded cloth will be wound flatly onto the take-up roller. When the take-up roller is fully wound with cloth, it is heavy and inconvenient to carry. Therefore, the unloading process of the weft straightening machine is more laborious.
