Therefore, in order to facilitate the forming of the bag strips, a bag cloth guide device is arranged between the unwinding and the sewing, and comprises a support, a left arc-shaped guide plate and a right arc-shaped guide plate which are fixed on the support and used for folding and guiding the bag cloth from two sides to the middle part, wherein the left arc-shaped guide plate and the right arc-shaped guide plate can gradually draw the left side edge and the right side edge of the bag cloth together.

However, the above-mentioned bag cloth guide device has the following disadvantages in practical operation:

1) the relative positions and angles of the left arc-shaped guide plate and the right arc-shaped guide plate are fixed, so that the use function is limited, and once the width of the filter bag cloth is adjusted, the guide effect cannot be achieved.

) The bag cloth can be folded only by a certain distance between the bag cloth guiding device and the unwinding roll, the bag cloth is not supported for a long distance, the bag cloth spans downwards, the subsequent fusion or sewing quality of the filter bag is directly influenced, and the caliber uniformity of the filter bag cannot be guaranteed.
