Once the Bag Closing System reaches operational status, the bag is fed into the machine, where a gripping chain secures the bag mouth and conveys it continuously. When the dust removal mechanism detects the bag at the designated position, it activates to remove dust from the bag mouth, deactivating promptly as the bag moves past. Upon detection by the stitching mechanism, the sewing machine engages to stitch the bag mouth; after the bag exits the sewing unit, the thread tail is cut and the bag mouth is trimmed.

When the paper tape feed mechanism detects the bag at the designated position, it feeds the tape to wrap the bag mouth before cutting the tape. Finally, the heat-sealing mechanism seals the tape, followed by pressing and counting to complete the sealing process.

Different bags require different sealing processes. Our bag closing system can be configured to meet your specific packaging needs, handling operations such as stitching, inner liner sealing, folding, tape sealing, or combined sealing methods.
