A jumbo bag side seam often runs along most of the bag-body height. Folded edges, reinforcement fabric, or coated woven material may create additional layers at certain positions. Equipment selection should therefore consider bobbin-thread capacity, feeding structure, stitch range, and the ability to pass through thickness transitions—not only maximum sewing speed.
The DS9800 FIBC Sewing Machine uses a large shuttle hook that accommodates more bobbin thread for heavy-thread side seam sewing. Because the exact bobbin capacity is not specified, a fixed continuous sewing length should not be claimed.
The large shuttle hook provides a larger bobbin-thread reserve, reducing the need for frequent bobbin replacement during long bag-body seams. The actual replacement interval depends on thread size, stitch length, bag height, and the number of seam rows.
For double-row or multiple-row side seams, thread consumption should be evaluated according to the seam drawing rather than estimated from a single seam line.
A side seam may change from two layers of woven fabric to folded or locally reinforced areas. The DS9800 uses an upper-and-lower compound-feed mechanism to move both material layers during sewing, making it suitable for long, straight seams in multilayer PP woven fabric.
Before production, sample sewing with the actual bag material should be conducted. Operators should check layer displacement, seam deviation, skipped stitches, and needle-hole condition before adjusting the presser foot, needle, thread, and stitch length.

This FIBC Sewing Machine is primarily used for jumbo bag side seams, long bag-body joining, folded-edge seams, and local reinforcement-fabric connections. It can also process other heavy industrial packaging bags that require heavy-thread sewing. Load-bearing areas such as lifting-loop joints require separate confirmation of the specified stitch pattern, number of seam rows, and applicable load tests.
No. Its main functions are increased bobbin-thread capacity and heavy-thread compatibility. Seam strength also depends on the fabric, thread, stitch length, number of seam rows, and seam structure.
Not by default. The 800–1000 stitches/min value is the maximum sewing-speed range. The operating speed should be adjusted for fabric layers, thread size, and thickness transitions.
Woven fabrics differ in weight, coating condition, and overlapping thickness. Sample sewing allows the operator to check feeding, needle holes, skipped stitches, and layer displacement before production settings are finalized.
