Description

30-Inch Long-Arm Sewing for Oversized Materials

The HighTex 728-30 is built for applications where a conventional industrial sewing machine simply doesn’t provide enough room to manage the workpiece.

Its extended arm provides approximately 762mm (30 inches) of clearance to the right of the needle, giving operators a dramatically larger working area for bulky and oversized materials.

The high 145mm under-arm clearance further improves access when positioning large assemblies beneath the machine arm.

This makes the 728-30 particularly valuable for manufacturers working with products that are difficult to fold, rotate, or maneuver around a standard sewing machine.

762mm / 30-Inch Working Clearance

The defining feature of this machine is its exceptionally long arm.

762mm (30″) clearance

That’s approximately three times the working length of a conventional industrial sewing-machine arm.

The extended workspace is especially useful for:

• Large tents
• Tarpaulins
• Parachutes
• Geotextile tubes
• Heavy canvas
• Large upholstery panels
• Industrial covers
• Oversized textile assemblies

The additional room allows large sections of material to remain supported while they move through the sewing area.

---

Double-Needle Compound-Feed System

The 728-30 combines a double-needle configuration with a synchronized triple-feed system.

The compound feeding mechanism coordinates:

• Bottom feed
• Needle feed
• Walking-foot top feed

This helps maintain controlled movement through multiple layers of heavy material and reduces unwanted shifting during sewing.

For large industrial products, consistent feeding is particularly important because even small variations in material movement can affect long seams.

---

Two Extra-Large Vertical-Axis Hooks

The 728-30 is equipped with two extra-large vertically mounted hooks and bases.

These large-capacity hook assemblies are designed specifically for heavy-thread applications and provide substantially greater bobbin capacity than conventional industrial hooks.

The machine can accommodate very thick thread, with the source specification listing:

Upper thread: #8–#0

Lower thread: #8

Up to approximately Nm 10/3

This makes the 728-30 suitable for both heavy structural seams and prominent decorative stitching.

The increased hook capacity also helps reduce interruptions during long sewing cycles.

---

Heavy-Duty Needle Penetration

Large industrial textile products often contain several layers of material, reinforced sections, folded edges, and overlapping seams.

The 728-30 is designed with strong needle penetration capability to help sew through these demanding areas while maintaining controlled stitch formation.

This is particularly useful for:

• Reinforced seams
• Cross seams
• Multiple material layers
• Folded canvas
• Heavy webbing assemblies
• Thick upholstery
• Industrial textile products

---

23mm Presser-Foot Lift

The machine provides up to 23mm of presser-foot lift, giving the operator generous clearance for thick and bulky materials.

The walking-foot system has a 9mm alternating stroke, allowing the presser foot to negotiate differences in material thickness as the workpiece moves through the machine.

This is particularly valuable when sewing reinforced or overlapping sections of large textile products.

---

10mm Stitch Length

The 728-30 can produce stitches up to 10mm long.

This provides flexibility for both heavy-duty assembly seams and bold decorative topstitching.

Longer stitch lengths can be particularly useful when working with heavy canvas, upholstery, industrial textiles, and products where a substantial stitch appearance is desirable.

---

Safety Clutch Protection

A built-in safety clutch helps protect important mechanical components if the machine becomes jammed or overloaded.

The clutch is designed to help reduce the risk of damage to components such as the:

• Hook
• Bevel gears
• Other critical drive components

This is an important feature on a machine designed to handle exceptionally heavy materials and thick thread.

---

Low-Speed Servo Control

The 728-30 is powered by a Kinedyne HM-1000SH low-speed servo motor.

Although the machine is capable of sewing at up to 1,200 stitches per minute, the servo allows the operator to work at much slower, controlled speeds when precision is required.

This is particularly useful when:

• Following complex seams
• Working around corners
• Positioning large panels
• Sewing reinforced areas
• Starting heavy seams
• Performing detailed stitching

The result is better operator control without sacrificing the machine’s heavy-duty capability.

---

Designed for Large Industrial Products

The 728-30 is particularly suited to manufacturers working with large flexible materials.

Tent & Canvas Manufacturing

• Industrial tents
• Heavy canvas structures
• Temporary shelters
• Canvas covers

Industrial Textile Products

• Tarpaulins
• Geotextile tubes
• Industrial covers
• Reinforced textile assemblies

Specialized Applications

• Parachute-related textile work
• Heavy technical textiles
• Large upholstery products
• Oversized fabric assemblies

Its large arm clearance is especially valuable when the workpiece cannot easily be compressed or folded during sewing.

---

Parts Interchangeability

The 728-30 is designed with parts interchangeability in mind for manufacturers already familiar with comparable long-arm industrial platforms.

The source identifies compatibility with machines such as:

• Consew 745R-30
• Seiko JW-28BL-30
• JUKI LG-158

This can be advantageous for workshops that already maintain equipment based on these platforms and want greater flexibility when sourcing compatible components.

---

Single-Needle Version Available

For applications that do not require double-needle stitching, a single-needle 718-30 version is also available.

This gives businesses the option to select the long-arm configuration that best matches their particular production requirements.

Why Choose the HighTex 728-30?

The 728-30 is designed around one fundamental requirement: large-scale sewing with large-scale materials.

Its 30-inch working arm provides the workspace necessary to handle oversized products, while the double-needle compound-feed system provides controlled feeding through multiple layers.

The combination of dual extra-large hooks, heavy-thread capability, 23mm foot lift, powerful needle penetration, safety clutch protection, and low-speed servo control makes this a serious industrial machine for demanding textile production.

For manufacturers producing tents, tarpaulins, parachutes, geotextile tubes, heavy canvas, upholstery, and other oversized textile products, the 728-30 provides the workspace and heavy-duty sewing capabilities required for these applications.
