BUILT FOR INDUSTRIAL SEAMS

Why a Double-Thread Chain Stitch?

Industrial bag seams need strength while still allowing the material to flex during handling, stacking and transportation. The DN-2HS uses two threads to create a secure chain stitch suited to demanding bag materials.

  • Strong two-thread seam
  • Flexible stitch construction
  • Suitable for heavier materials
  • Consistent industrial sewing

FROM MATERIAL TO FILLED BAG

How the DN-2HS Fits the Process

The DN-2HS creates the sewn bag from prepared material. If the bag will also be filled at the same operation, filling and final bag closing typically follow as separate, small-scale steps.

01
MATERIAL

Prepare Material

Paper, woven PP or PE, jute or another compatible bag material is prepared for the required construction.

02
SEW

Sew With the DN-2HS

The DN-2HS joins and hems the material to create the required seams and form the empty bag.

03
FILL

Fill

If product packaging is performed at the same operation, the finished empty bag can then be filled manually or with an appropriate filling method.

04
CLOSE

Close

After filling, the open top can be sewn closed using portable or stationary bag-closing equipment suited to the production level.

SMALL-SCALE PACKAGING OPTIONS

Filling & Closing the Finished Bag

Operations making bags with a DN-2HS typically do not require a large automated packaging line. When those bags are also filled on site, a simpler closing setup may be more appropriate.

SIMPLE / MANUAL

Manual Fill + NP-7A

Fill Bag NP-7A

For low-volume production, the bag can be filled manually and sewn closed using the Newlong NP-7A portable bag closer.

SMALL STATIONARY SETUP

Fill + A1-PB / DS-9C

Fill Bag A1-PB + DS-9C

For a stationary closing setup, the A1-PB can be paired with the DS-9C sewing head. A small conveyor can also be incorporated when additional bag handling is appropriate.
