GKS-243D Heat Sealing Stitching Machine

• Optional Bag Mouth Cleaning: The bag-mouth cleaning function can be included as an optional stage before the sealing process. • Inner Bag Heat Sealing: The inner PE liner is heat sealed using four heating blocks. This establishes the internal closure before the outer bag is stitched. • Pressure Roller Processing: The sealed bag mouth is processed through pressure rollers before the next preparation stage. • Bag Mouth Trimming: A cutter trims the bag mouth to prepare the outer paper bag for stitching. • Outer Bag Stitching: The outer paper bag is stitched using the integrated sewing system. The catalogue specifies GS-7C as the sewing head. • Hot-Melt Adhesive Tape: Hot-melt adhesive tape is then applied to the outer closure area. • Final Heat Sealing: The adhesive tape is heat sealed using three heating blocks, activating the hot-melt adhesive and completing the external closure. • Final Pressure Processing: Pressure rollers process the final adhesive-sealed area to complete the documented workflow.
