DT 928 Three needle feed-off-the-arm chainstitch sewing machine

The DT 928 is a high-performance 3-needle feed-off-the-arm chain stitch sewing machine, also known as a cylinder bed interlock machine. It features a cantilevered cylinder arm structure specifically designed for lap seaming of tubular parts such as cuffs, sleeves, and trouser legs. The machine produces three perfectly parallel chain stitch lines in a single pass, making it the preferred choice for jeans side seams, trouser leg seams, shirt cuffs, and other applications requiring multiple parallel stitches.

With its improved chain stitch mechanism, low-tension sewing, and optional puller configurations, the DT 928 delivers beautiful, wrinkle-free seams on light to heavy fabrics, from shirts and windbreakers to denim and sportswear.

Applications

The DT 928 is applicable to a wide range of garments and materials, including:

• Shirts – cuffs, side seams, and decorative triple stitching

• Windbreakers – lightweight outerwear seams

• Jeans – side seams, inseams, and topstitching

• Sportswear – stretchable and durable seams on knit and woven fabrics

• Trousers – lap seaming on tubular legs

• Sleeves – attaching sleeves to garment bodies

• Any tubular or cylindrical part requiring lap joint sewing

The machine handles materials ranging from light to heavy, making it versatile for mixed production lines.

Key Features

1. Cantilevered Cylinder-Type Structure

The special cantilevered cylinder-type structure is especially suitable for cylinder-type lap joint sewing, such as sleeves and trousers. The narrow cylinder arm allows tubular garment sections to be slipped directly onto the machine, enabling continuous circular stitching without repositioning.

• Ideal for closed tubular parts

• Reduces handling time

• Suitable for thin and mid-thick materials

2. Improved Chain Stitch Mode with Low Tension

The DT 928 has undergone thorough improvement of the chain stitch mode, achieving low tension for both needle thread and bottom thread. Through adjusting the needle mechanism and improving the curved needle and other positioning parts, the machine produces beautiful stitches instead of drape or puckering.

• Reduces thread breakage

• Eliminates puckering and wrinkling

• Produces clean, even stitch lines

• Enhances seam appearance

3. External Tug (Puller) for Smooth Material Handling

The external tug (puller) offers many advantages, including:

• Pulling material smoothly and evenly

• Producing neat stitches

• Flexible usability for different fabric types

• Preventing fabric shifting during sewing

The puller can be internal or external depending on the model variant, providing options for different production needs.

4. Independent Curved Needle Adjustment Structure

The machine features an independent curved needle adjustment structure that avoids distraction and thread breakage. The improved sewing structure with low-tension sewing prevents wrinkles and ensures consistent stitch quality.

• Independent looper adjustment for precise control

• Reduces thread breakage and skipped stitches

• Maintains stable performance on difficult fabrics

Common Questions

1. What type of machine is the DT 928 3-Needle Feed-off-the-arm Chain Stitch Sewing Machine?

The DT 928 is a 3-needle feed-off-the-arm chain stitch machine (cylinder bed interlock machine). It features a cantilevered cylinder arm structure specifically designed for lap seaming of tubular parts such as cuffs and trouser legs.

The 928 is a classic 3-needle model, widely used for processes requiring three parallel stitch lines, such as:

• Jeans side seams

• Trouser leg seams

• Shirt cuffs

• Decorative triple stitching

2. What are the core advantages of this machine?

The DT 928 offers several core advantages:

1. Cylinder arm structure: Especially suitable for lap seaming of tubular parts like cuffs and trouser legs, allowing easy loading of closed tubular sections.

2. Improved chain stitch method: Achieves low tension for both needle and looper threads, reducing thread breakage and improving seam reliability.

3. Eliminates puckering: Through significant improvements in thread tension mechanisms and looper positioning parts, the machine eliminates puckering and achieves neat, flat stitches.

4. Built-in mechanical direct-drive puller: Smoother material feeding and flatter seams, especially on heavy or slippery fabrics.

5. Wide applicability: Suitable for light to medium-weight fabrics, including shirts, windbreakers, jeans, and sportswear.

3. What are the other specifications of this machine?

The DT 928 is available in several configurations:

• DT 928: Standard three needle feed-off-the-arm sewing machine.

• DT 928-PL: Equipped with an internal puller for enhanced feeding.

• DT 928-PS: Equipped with an external puller for maximum material control.

The choice between internal and external puller depends on the specific application and fabric type. Internal pullers are more compact and suitable for standard operations, while external pullers provide stronger feeding force for heavy or slippery materials.
