Processing equipment and method for guaranteeing breadth of woven bag body

The invention discloses processing equipment for guaranteeing the breadth of a woven bag body, which comprises a circular weaving machine, an unwinding mechanism, an unwinding tensioning mechanism, a winding mechanism and a winding tensioning mechanism, the unwinding mechanism is arranged on one side of the circular weaving machine, a plurality of unwinding cylinders are arranged on the unwinding mechanism, the unwinding tensioning mechanism is arranged between the unwinding mechanism and the circular weaving machine, and the winding tensioning mechanism is arranged on the other side of the circular weaving machine. The weft yarns are tensioned through the unwinding and tensioning mechanism, so that the weft yarn density is ensured; a winding mechanism is further arranged outside the circular weaving machine, and a winding tensioning mechanism is arranged between the winding mechanism and the circular weaving machine. A spinning shuttle is arranged in the circular weaving machine, warps are clamped on the spi
