Woven Bag Conversion Line

Product Description

A entire production system or assembly line used for the production and conversion of woven bags is referred to as a woven bag conversion line. It makes use of numerous tools and procedures to convert raw materials into completed woven bags that are prepared for use or distribution. Depending on the intended bag type, size, and output, a woven bag conversion line's precise configuration may change.

Here are some essential elements that are frequently present in a woven bag conversion line:

1. Extrusion Machine: Using this device, plastic resin, such as polypropylene (PP) or polyethylene (PE), is melted and extruded to create a continuous flat tape. The fundamental material for weaving the bags is the extruded tape.

2. Circular Looms: The main fabric used to make woven bags is tubular fabric, which is created by weaving flat tapes on circular looms. A woven structure is produced by these looms' numerous shuttle mechanisms, which move the tapes both horizontally and vertically.

3. Printing Machine: If required, a printing machine can be added to the production line to imprint special patterns or branding on the woven fabric prior to the creation of bags. It might make use of gravure or flexographic printing processes.

4. A bag cutting machine is used to cut the woven fabric into individual bag panels or certain bag sizes, as was previously indicated. It may be fitted with a variety of cutting tools, such as revolving blades or cutters in the guillotine fashion.

5. After being cut, the bag panels are fed into bag sewing machines where they are stitched. To produce sturdy and long-lasting seams, these machines use specialised stitching methods including double-fold sewing or bottom folding.

6. Gusseting Machine (Optional): A gusseting machine is used to fold and shape the fabric before sewing, assuring the ideal bag form and volume. This is done for bags with gussets (expandable sides or bottoms).

7. Printing Registration Machine (Optional): A printing registration machine can be added to the line if perfect printing alignment is necessary. Before stitching, it aids in correctly aligning the printed design on the bag panels.

8. Various finishing procedures, such as heat cutting to seal the edges, punching holes for handles or ventilation, or affixing attachments like zippers, Velcro, or handles, may be integrated into the bag-making process.

9. Quality Control Systems: Quality Control Systems may be used to check the woven bags for flaws like incorrect stitching, printing mistakes, or dimensional accuracy along the conversion line. This guarantees the final bags' constant quality.

10. Finally, the final bags are gathered and packaged using packing equipment and conveyors for storage, distribution, or additional processing.

A well-planned woven bag conversion line assures consistent bag quality and output while increasing production efficiency and reducing manual labour. It is a full solution for the entire production of woven bags, from raw materials to finished goods.
