Overview of the Shibang-2628 Cylinder-Type Sewing Machine

The Shibang-2628 is engineered with a specialized cylinder arm design that enables sewing on curved, tubular, or irregular surfaces. Unlike flat-bed machines, the cylinder arm allows operators to maneuver and stitch leather, canvas, and other thick materials more easily. This makes it ideal for manufacturing footwear, gloves, bags, and other products with complex shapes.

Key highlights include:

• Cylinder-type arm for flexible material handling

• Single needle lockstitch mechanism ensuring strong, durable stitches

• Heavy-duty construction suited for thick and tough materials

• Adjustable stitch length and speed controls for precise tailoring

• Reliable feed mechanism for consistent fabric movement

Design and Build Quality

Cylinder Arm Configuration

The defining feature of the Shibang-2628 is its cylinder arm, a narrow tubular arm extending from the base that allows fabric to be wrapped and stitched around it. This design is especially beneficial when working with footwear uppers, sleeves, or cylindrical bags, where flat-bed machines are ineffective.

Robust Frame and Components

Manufactured with high-grade cast iron and steel, the machine’s frame guarantees stability and longevity even in high-volume production environments. The durability ensures minimal vibration during operation, enhancing stitch quality and operator comfort.

Needle System and Presser Foot

Equipped with a high-precision single-needle system, the Shibang-2628 produces consistent lockstitch patterns. The presser foot is designed to hold materials firmly in place without damaging delicate surfaces.

Advanced Feed Mechanism

The integrated feed dog system works in sync with the needle to advance material steadily, preventing puckering or slipping. This ensures uniform stitch length and a professional finish.

• Securely mount the machine on a sturdy worktable.

• Connect the power supply and motor (direct-drive recommended for smooth operation).

• Thread the machine according to manufacturer's guidelines, ensuring proper tension.

Material Preparation

• Choose the appropriate needle and thread based on material thickness and type.

• Position materials carefully on the cylinder arm for optimal stitching.

Stitch Adjustments

• Set stitch length according to the material and application.

• Adjust the presser foot pressure to avoid material damage.

Sewing Technique

• Guide materials gently and steadily.

• Monitor stitching speed and adjust to avoid skipped stitches.

Maintenance and Troubleshooting

Regular Lubrication

Utilize the built-in automatic lubrication system to keep moving parts well-oiled, reducing friction and wear.

Needle and Thread Checks

Replace needles regularly to avoid fabric damage and stitch defects. Use the correct thread size and quality.

Cleaning

Remove lint and debris from the feed dog and bobbin areas daily to ensure smooth operation.

Common Issues and Solutions

• Skipped stitches: Check needle condition and thread tension.

• Material feeding problems: Inspect the feed dog height and presser foot pressure.

• Motor overheating: Allow the machine to cool and check the motor specifications.

Comparison with Other Industrial Sewing Machines

Cylinder vs. Flat-Bed Machines

Cylinder-type machines excel at sewing curved and tubular materials where flat-bed machines fall short. The Shibang-2628 is particularly effective for footwear and leather applications.

Single Needle vs. Double Needle Machines

Single-needle machines like the 2628 provide greater flexibility for intricate and tight areas, while double-needle machines offer efficiency in parallel stitching but lack the maneuverability.

Manual vs. Computerized

While computerized machines provide automation and programmability, the Shibang-2628's mechanical design offers reliability, easier maintenance, and cost-effectiveness for straightforward stitching needs.
