DT 8752E Computerized direct drive double needle lockstitch sewing machine with split needle bar

The DT 8752E is a professional direct drive computerized double needle lockstitch sewing machine featuring a split needle bar system. It is engineered for high-quality double stitch sewing, producing two perfectly parallel seams in a single pass. The machine combines synchronized needle bar and feed dog feeding, intelligent automation, and energy-efficient direct drive technology, making it an ideal choice for garment manufacturers producing shirts, uniforms, jeans, coats, and similar products.

With its robust construction and advanced features, the DT 8752E delivers superior stitch consistency, dramatically improved work efficiency, and reduced operating costs.

Applications

The DT 8752E is suitable for sewing a wide range of garments and products where double-needle stitching is required. Typical applications include:

• Shirts – plackets, cuffs, collars, and side seams

• Uniforms – professional double seams on workwear and corporate clothing

• Jeans – side seams, inseams, and decorative topstitching

• Coats and jackets – double-needle seams on outerwear

• Bags and accessories – zipper attachment and reinforced seams

• Decorative stitching – parallel topstitching for high-end finishes

The machine offers strong adaptability to different seam materials and prevents seam material slippage because needle feeding and feed teeth feed simultaneously. This makes it especially suitable for high-quality double stitch and decoration processes where precise, even stitch lines are essential.

Key Features

1. Synchronized Needle Bar and Feed Dog Feeding

The DT 8752E features synchronized fabric feeding of the needle bar and feed dog, effectively preventing fabric slip and ensuring fine adaptation to different fabrics. This results in:

• Precise stitch formation

• No shifting between fabric layers

• Nice, even stitches

• Excellent performance on high-quality double stitch and decorative sewing work

This synchronized feeding mechanism is critical for maintaining parallel stitch consistency, especially on slippery or multi-layer materials.

2. Intelligent Sewing Functions

The machine is equipped with multiple smart sewing features that dramatically improve work efficiency:

• Automatic thread trimming – cuts both needle and bobbin threads at the end of each seam

• Needle positioning – programmable needle up/down position for easy fabric handling

• Needle counting – tracks stitch count for maintenance and production monitoring

• Reverse sewing – automatic backtacking at seam start and end for reinforcement

• Thread swapping – simplified thread change process

• Many other smart sewing modes – customizable settings for different production needs

These automation features reduce manual operations and allow operators to focus on fabric handling, increasing overall productivity.

3. Direct Drive Computerized Servo Motor System

The machine adopts a direct drive computerized servo motor system, offering power saving of more than 40% compared with traditional clutch motors.

Benefits include:

• Significant energy cost reduction

• Low vibration and quiet operation

• Fast response and accurate needle positioning

• Less maintenance (no belt wear)

• Stable performance during long runs

4. Automatic Mini-Oil Lubricating System

The DT 8752E is equipped with an automatic mini-oil lubricating system with a liquidometer in the body. This allows operators to easily observe whether oil is present and ensures proper lubrication at all times.

• Automatic oil supply to critical components

• Transparent oil level indicator

• Prevents premature wear and extends machine life

• Reduces manual oiling tasks

5. Best Design of Outlook and Interior Structure

The machine features an optimized exterior and interior structure design, making it easy to maintain and use.

• Clean, modern appearance

• Logical internal layout for quick access

• Simplified maintenance procedures

• Durable construction for long-term reliability

Common Questions

1. What is the main purpose of the DT 8752E? Which industries is it suitable for?

The DT 8752E is a professional synchronous double needle machine. It is primarily used for sewing two perfectly parallel lines at once, making it ideal for:

• Jean side seams and inseams

• Pocket styling and decorative topstitching

• Shirt plackets and cuffs

• Bag zippers and reinforcements

• Uniform seams and workwear construction

It is widely used in garment manufacturing, especially in the production of denim, shirts, uniforms, workwear, coats, and bags.

2. How is it different from a single-needle machine? What are its advantages?

The key difference is the DT 8752E's ability to sew two perfectly parallel and consistent stitches in one pass. This doubles efficiency compared with a single-needle machine and ensures far superior consistency than sewing two lines separately.

Advantages include:

• Increased productivity – two stitch lines in one operation

• Guaranteed quality – perfectly parallel and evenly spaced stitches

• Simplified operation – guide feet or edge guides ensure straight lines

• Professional finished appearance – clean double topstitching

• Reduced handling time – no need to reposition fabric for second pass

3. What material thickness can it handle?

The DT 8752E is designed for medium to heavy-weight materials. Its robust feeding system, high-torque motor, and sturdy construction allow it to easily sew through multiple layers of:

• Denim

• Canvas

• Leather (non-extreme thickness)

• Synthetic leather

• Coated fabrics

The exact capability depends on stitch length and material stiffness. For specific application advice, please consult our team with your material details.

4. Is the spacing between the two needles adjustable? What are the common spacings?

Yes, this is a key feature of the split needle bar design. The needle spacing on the DT 8752E is typically changed by replacing the needle bar and presser foot assembly to achieve different gauges.

Common needle spacings include:

• 1/4 inch (approx. 6.35mm)

• 3/16 inch (approx. 4.76mm)

• Other gauges from 3/16"to 1/2"depending on configuration

You can configure or purchase different gauge sets based on your needs when ordering or through after-sales service.

5. What are the key points for using double needles?

To achieve the best results and avoid common issues, follow these key points:

1. Always use matched, high-quality twin needles of the same specification. Mismatched needles can cause uneven stitches or fabric damage.

2. Threading must be correct – each thread must pass independently through its own tension path without interference.

3. Match needle and thread size to the fabric – use heavier needles and thread for thick materials to prevent breakage.

4. Clean the hook area regularly – double-needle sewing generates more lint, which can affect stitch quality if not removed.

6. Can it be converted to a single-needle machine?

Technically, the DT 8752E can be converted to single-needle operation by changing the needle bar, presser foot, and related components. However, frequent conversion is not recommended.

The machine is optimally designed for double-needle operation, and repeated conversions can affect performance and alignment. If you frequently need to switch between single and double needle sewing, we recommend using dedicated machines for each purpose to maintain efficiency and stitch quality.
