Local FIBC damage does not always occur on a flat bag-body panel. Filling spouts, discharge spouts, bag corners, folded edges, and tubular sections may provide limited operating space and require the material to be rotated along the original seam.
The GB6-180-2 FIBC Sewing Machine uses a cylinder-bed structure. Bag material can be positioned around or over the cylinder bed, providing a different handling method for narrow sections and curved repair seams.
The specified cylinder diameter is 91 mm. This value describes the structural size of the cylinder bed; it does not mean that the machine can only process a 91 mm-wide bag, nor does it indicate maximum sewing thickness.
Actual access depends on the bag opening, repair location, material flexibility, number of overlapping layers, and whether the damaged area can be positioned correctly under the needle. A physical sample or dimensions of the repair area should be provided before selection.
For local repair, the required bag section can be placed around the cylinder bed and gradually rotated during sewing. For circular seams or curved positions close to a spout, the seam path should be planned first so that the remaining bag material does not block the feeding direction.
The upper-and-lower compound-feed mechanism moves multilayer material through the needle area, while the operator controls bag rotation. Low-speed sample sewing should be performed to check stitch formation, fabric folding, and seam deviation at turning positions.
| Repair Position | Operating Focus |
|---|---|
| Filling-spout edge | Inspect the circular seam and bag-body connection |
| Discharge-spout edge | Check whether folded fabric can rotate freely |
| Bag corner | Control material accumulation and turning angle |
| Inside folded edge | Position the repair area around the cylinder bed |
| Local repair patch | Keep patch edges within the visible sewing area |
| Opened bag-body seam | Arrange the bag according to the seam direction |
Repairs involving lifting-loop roots or other load-bearing sections require separate evaluation against the specified stitch pattern and load requirements. Suitability cannot be determined from the cylinder-bed structure alone.

This FIBC Sewing Machine is mainly used for repairing seams in narrow areas of FIBCs, jumbo bags, and industrial packaging bags. Typical positions include spout edges, the inside of folded sections, bag corners, and local patches that are difficult to position on a flat-bed machine. The 91 mm cylinder bed provides space for inserting and rotating the material, while actual repair accessibility should be confirmed with the bag structure and sample sewing.
The operator should first confirm that the damaged area can be positioned safely around the cylinder bed. It is also necessary to check whether rotating the material will pull or distort other seams. For circular or curved repairs, the sewing path can be marked before a low-speed trial begins.
No. The 91 mm value is the specified cylinder diameter, not a minimum bag-opening size. Actual compatibility depends on the opening structure, material flexibility, and repair location.
No. It can also be used for bag corners, inside folded edges, and other local seams that are difficult to position on a flat-bed machine. The handling method should be verified by sample sewing.
The 800 stitches/min value is the maximum sewing speed. Narrow sections, curved seams, and turning positions may require a lower operating speed depending on the available space and material condition.
