Extra-Long Arm Sewing for Large Upholstery Projects

When working on a large sofa panel, automotive seat, or marine upholstery assembly, workspace can become just as important as machine power.

The HighTex 204-76-370 addresses that challenge with an extended sewing arm providing approximately 760mm of working clearance.

This exceptionally long arm gives the operator substantially more room to position, rotate, and support large workpieces while sewing.

It is particularly suited to:

• Large sofa and couch panels
• Lounge furniture
• Automotive seats
• Marine upholstery
• Large leather panels
• Heavy canvas assemblies
• Other oversized three-dimensional workpieces

760mm Extended Arm Clearance

The defining characteristic of the 204-76-370 is its 760mm-long working clearance.

Compared with conventional industrial flat-bed machines, the extended arm gives the operator significantly more space to maneuver large materials around the sewing head.

This is especially useful for:

✓ Lounge sofas and couches
✓ Large furniture panels
✓ Automotive interiors and seats
✓ Marine upholstery
✓ Large leather assemblies
✓ Heavy canvas products
✓ Three-dimensional upholstery work

The additional workspace helps reduce the difficulty of manipulating bulky material during long seams and large-panel sewing.

Heavy-Duty Triple-Feed System

The 204-76-370 uses a synchronized triple-feed mechanism, combining the movement of the needle, walking presser foot, and bottom feed.

This compound feeding action is designed to maintain consistent material movement even when sewing heavy or multiple-layer assemblies.

Triple-feed benefits include:

• Consistent stitch length
• Improved layer control
• Reduced material shifting
• Better handling of thick materials
• Controlled feeding through bulky seams
• More uniform stitch formation

For upholstery manufacturers, this is particularly important when working with multiple layers of leather, fabric, foam-backed materials, and reinforcement.

204 Large Barrel Shuttle Hook

The machine incorporates a 204-type large barrel shuttle hook, providing the capacity needed for heavy-duty sewing and thick thread.

It can accommodate thread sizes up to:

8/3 — V415 / T-400

or approximately 1mm braided thread

The large shuttle is particularly valuable for upholstery applications requiring substantial structural or decorative thread.

Its larger bobbin capacity also helps support longer sewing cycles before the operator needs to stop for a bobbin change.

---

Designed for Thick-Thread Upholstery

The 204-76-370 is not intended only for light decorative work.

Its heavy-duty hook and feeding system allow it to work with substantial thread while maintaining controlled stitch formation.

This makes it appropriate for applications where stitching needs to provide both:

• Structural strength
• A pronounced decorative appearance

The machine supports stitch lengths up to 14mm, giving upholstery manufacturers considerable flexibility for bold topstitching and assembly seams.

---

20mm Presser-Foot Lift

The presser foot can lift up to 20mm, providing substantial clearance for bulky materials.

This makes it easier to position:

• Thick leather
• Layered upholstery
• Padded assemblies
• Heavy canvas
• Multiple material plies
• Bulky seams

The walking foot also provides up to 10mm of alternating movement, helping the machine negotiate different material thicknesses and raised sections.

---

Excellent Material Climbing

Large upholstery assemblies often contain areas where material thickness suddenly changes.

The 204-76-370’s heavy-duty feeding mechanism and substantial walking-foot stroke are designed to help the machine climb over these variations while maintaining controlled feeding.

This is particularly useful for:

• Overlapping seams
• Cross seams
• Padded sections
• Multiple leather layers
• Reinforced areas
• Thick upholstery transitions

---

Precision Sewing with Low-Speed Servo Control

The machine is powered by a Kinedyne low-speed, high-torque servo motor, providing controlled operation when precision is more important than maximum sewing speed.

The slow-speed capability is useful for:

• Following curves
• Sewing corners
• Positioning large panels
• Decorative stitching
• Working around thick seams
• Detailed upholstery work

The source specifies a Kinedyne HM-1000SH servo motor configuration, providing substantial power while allowing the operator to work at a controlled pace.

---

Pneumatic Production Controls

The 204-76-370 comes equipped with several features designed to improve production efficiency.

Standard equipment includes:

✓ Pneumatic presser-foot lift
✓ Pneumatic reverse stitching
✓ Automatic needle UP/DOWN positioning

These controls reduce repetitive manual operations and are particularly useful in professional upholstery production where the machine may be operated continuously.

---

Electronic Jog Dial

Needle-bar adjustments and machine positioning can be simplified using the integrated electronic hand wheel / jog dial.

This provides the operator with an additional control interface for making precise adjustments during setup and detailed sewing operations.

---

Built for Large Three-Dimensional Work

The long-arm configuration makes the 204-76-370 particularly useful for sewing workpieces that are difficult to manage under a conventional machine arm.

The machine is designed around the needs of professional upholstery manufacturers handling large, bulky products.
