DT 254 Computerized double needle belt loop sewing machine

The DT 254 is a fully automatic double needle belt loop attaching machine designed for one-time forming and sewing of belt loops on jeans, casual pants, workwear, and other trousers. It integrates automatic screening, length cutting, folding, and bartacking into one seamless process, requiring no manual assistance throughout the entire operation.

This machine is the ideal solution for garment manufacturers looking to eliminate labor-intensive belt loop operations, improve consistency, and dramatically increase production speed.

Applications

The DT 254 is suitable for belt loop attaching on a wide range of trousers and bottoms, including:

• Jeans – classic 5-pocket denim with single or multiple belt loops

• Casual pants – chinos, cargo pants, and everyday wear

• Workwear – durable trousers requiring reinforced belt loops

• Uniforms – consistent belt loop placement for mass production

• Shorts – belt loops on casual and denim shorts

The machine can handle belt loop widths of 7–20mm and finished belt loop lengths of 45–78mm, covering most standard garment requirements.

Key Features

1. Suitable for Jeans, Casual Pants, and More

The DT 254 is specifically engineered for belt loop attaching on jeans, casual pants, workwear, and similar garments. Its robust design handles denim and other medium-to-heavyweight fabrics with ease.

2. Easy to Program Personalized Patterns

The machine allows you to easily program any personalized pattern required, in addition to the normal bartacking design. This flexibility means you can create custom bartack shapes, stitch counts, and belt loop configurations directly from the control panel.

• No mechanical cam changes

• Store multiple patterns in memory

• Quick recall for different styles and orders

3. Automatic Belt Detection and Positioning

The DT 254 automatically feels the belt and requires no manual operation, ensuring exactly the same position every feeding. This intelligent detection system:

• Eliminates human error in positioning

• Maintains consistent belt loop placement on every garment

• Reduces rejects caused by misaligned belt loops

4. Automatic Folding After Cutting

After cutting, the machine automatically folds the belt loop and sends it to the next step. This integrated folding mechanism ensures:

• Uniform fold shape and size

• No separate folding station required

• Smooth transition from cutting to bartacking

5. Continuous Double Bar Tacking Without Stopping

The machine does not require stopping to finish the double bar tacking. This continuous operation allows:

• Faster cycle times

• Increased throughput

• Smooth, uninterrupted production flow

6. Automatic Belt Cutting up to 75mm on Y Direction

The DT 254 automatically cuts the belt material, with a cutting range up to 75mm on the Y direction. This allows flexible belt loop lengths to be produced without manual cutting.

7. Adjustable Working Table Height

The height of the working table can be easily adjusted to match the operator's height. This ergonomic feature:

• Reduces operator fatigue during long shifts

• Improves comfort and productivity

• Allows different operators to work at their optimal height

Common Questions

1. What type of machine is the DT 254?

The DT 254 is a fully automatic double needle belt loop attaching machine designed for one-time forming and sewing of belt loops for jeans and casual pants.

It integrates automatic screening, length cutting, folding, and bartacking into one process, requiring no manual assistance throughout the entire operation. From raw belt material to finished attached belt loop, the machine handles every step automatically.

2. What are the core advantages of this machine?

The DT 254 offers several key advantages:

Highly Integrated: Automatically completes feeding, cutting, folding, and bartacking of belt loops. One operator can manage multiple machines simultaneously, significantly reducing labor costs.

Extremely Efficient: Sewing time per belt loop is only 1.2 seconds (with 28 stitches), increasing production efficiency by over 70% compared with traditional methods.

Labor Saving: Replaces 4 workers in processes such as belt loop cutting, folding, bartacking, and handling. This translates into substantial cost savings and faster return on investment.

Consistent Quality: Automatically detects and removes waste material at belt loop joints, ensuring finished product quality. The automated process eliminates variations caused by operator fatigue or skill differences.

Easy Adjustment: Belt loop length, width, and bartacking dimensions can be digitally set on the operation panel—no mechanical adjustments required. This enables quick style changeovers and flexible production.

3. What types of belt loops is it suitable for?

The DT 254 is suitable for belt loop sewing on jeans, casual pants, workwear, and similar garments.

It can handle:

• Belt loop widths: 7–20mm

• Finished belt loop lengths: 45–78mm

This wide range covers most standard belt loop specifications used in the apparel industry, making the machine versatile enough for various trouser styles and customer requirements.

4. Can the machine sew different bartack patterns?

Yes. In addition to the normal bartacking design, the DT 254 allows you to program any personalized pattern required. Bartack dimensions, stitch counts, and shapes can be digitally adjusted and saved, providing maximum flexibility without mechanical changes.

5. How does the automatic belt detection work?

The machine is equipped with sensors that automatically detect the belt material as it is fed. This ensures that each belt loop is positioned in exactly the same place every time, eliminating manual positioning errors and guaranteeing uniform results.
