[0054] The non-woven fabric enters the forming device c from the ironing handle device b to be folded. The two handles are folded inward under the action of the cross plate. The non-woven fabric after folding passes through the input guide roller assembly d2 to enter the edge inserting device d and is sleeved outside the guide frame d43. The two edges needing heat sealing enter between the ultrasonic welding pressure head and the edge covering wheel to be heat sealed. The non-woven fabric bag after heat sealing forms a ring shape and is sleeved outside the edge inserting metal plate d41 along the guide frame d43. With the advancement of the non-woven fabric bag, the edge inserting disc d42 inserts the edge of the non-woven fabric bag. The non-woven fabric bag after edge inserting leaves the edge inserting device through the output guide roller mechanism d5. The driving output guide roller d51 is driven by the guide roller motor d53 to provide power for the advancement of the non-woven fabric bag in cooperation with the passive output guide roller d52.

[0055] The non-woven fabric enters the slitting device e along the conveying direction. The bottom edge is heat sealed in the slitting device. The non-woven fabric is cut into individual non-woven fabric bags.
