JACK A5E-B AMH2 LARGE SPACE COMPUTERISED LOCKSTITCH SEWING MACHINE WITH ELECTRONIC STITCH LENGTH

The JACK A5E-B AMH2 Large Space Computerised Industrial Lockstitch Sewing Machine is an advanced single-needle, direct-drive industrial sewing machine designed for professional garment manufacturing, tailoring, textile production and commercial sewing applications.

Featuring JACK's innovative Smart Fabric Adaptive System, Octopus Dual-Core AI Chip and Vigorous Ape Dual-Drive Motor, the A5E-B intelligently adapts its sewing performance to changing fabric thicknesses, delivering consistent stitching quality across a wide range of medium-weight materials.

The machine features an extended 305mm working space between the needle and machine body, providing additional room for handling larger garments, fabric panels and bulky sewing projects.

Unlike conventional industrial lockstitch sewing machines, the JACK A5E-B AMH2 incorporates an electronically controlled stitch length and bartacking system, operated by a precision stepper motor. This provides accurate stitch adjustments, consistent reverse stitching and improved control during production.

The integrated automatic thread trimming system cuts the thread to approximately 3.5mm, reducing the need for manual trimming and helping improve productivity.

A convenient set of three function buttons positioned near the needle bar provides quick access to half-stitch positioning, additional stitch insertion and bartacking functions.

The machine also features a semi-dry head lubrication system, eliminating the oil supply to the needle bar drive mechanism to help minimise the risk of oil stains on fabrics.

With a maximum sewing speed of 5,000 stitches per minute, intelligent fabric adaptation and an energy-efficient direct-drive motor, the JACK A5E-B AMH2 combines advanced technology with the speed and reliability required for professional industrial sewing environments.

Ideal for clothing manufacturers, fashion designers, tailoring workshops, alteration businesses, textile factories, colleges, universities and professional sewing rooms.

SMART FABRIC ADAPTIVE SYSTEM

The JACK A5E-B AMH2 Smart Fabric Adaptive System is designed to automatically respond to changes in material thickness during sewing.

Traditional industrial sewing machines often require manual adjustments when switching between different materials or sewing over thicker seams.

The A5E-B uses intelligent electronic control to help maintain consistent sewing performance when fabric thickness changes.

The system combines advanced processing technology with a responsive motor to optimise needle penetration and fabric feeding.

Benefits include:

• Automatic response to changing fabric thickness
• Improved stitching consistency across varying material layers
• Reduced need for manual machine adjustments
• Smoother sewing over suitable raised seams
• Improved productivity during garment manufacturing
• More consistent sewing performance

This technology is particularly useful when sewing garments containing multiple seams, folded edges and varying fabric thicknesses.

EXTENDED 305MM LARGE WORKING SPACE

The JACK A5E-B AMH2 features an extended machine body, providing 305mm of working space between the needle and machine body.

This additional workspace makes it easier to position and manoeuvre larger pieces of material compared with standard industrial lockstitch machines.

The increased working area is particularly useful for:

• Large garment panels
• Jackets and coats
• Dresses and workwear
• Curtains and soft furnishings
• Larger textile products
• Bulky fabric assemblies
• Commercial garment production

The extended machine body provides additional flexibility when handling materials that require more room during stitching.

OCTOPUS DUAL-CORE AI CHIP

The Octopus Dual-Core AI Chip is one of the JACK A5E-B's main technological features.

Designed to monitor and respond to changes in sewing conditions, the chip processes information relating to material thickness and automatically adjusts relevant machine parameters.

This intelligent system works alongside the motor and electronic controls to maintain consistent sewing performance.

Key advantages:

• Real-time fabric thickness adaptation
• Intelligent machine performance adjustment
• Improved needle penetration control
• Consistent stitching across varying material layers
• Reduced operator intervention
• Improved efficiency during continuous production

The Octopus Chip helps make the A5E-B suitable for production environments where operators frequently encounter changing fabric thicknesses.

VIGOROUS APE DUAL-DRIVE MOTOR

The JACK A5E-B features the advanced Vigorous Ape Dual-Drive Motor, designed to provide rapid motor response and increased needle penetration force.

According to the supplied manufacturer information, the motor delivers:

• 11.3 Nm peak torque
• Up to 4 times faster motor response
• 22.5% higher power density
• Enhanced needle penetration performance
• Responsive speed control
• Consistent power delivery during sewing

The motor works together with the Octopus Dual-Core AI Chip to provide intelligent control over sewing performance.

Its high-torque design is particularly useful when sewing through suitable multi-layered materials or transitioning between different fabric thicknesses.

ELECTRONICALLY CONTROLLED STITCH LENGTH

Unlike conventional industrial lockstitch machines that rely on mechanical stitch-length adjustment systems, the JACK A5E-B AMH2 features an electronically controlled stitch-length mechanism.

A precision stepper motor controls stitch length and bartacking functions, helping provide accurate and repeatable stitching adjustments.

Advantages include:

• Precise electronic stitch-length adjustment
• Consistent stitch formation
• Electronically controlled reverse stitching
• Improved bartacking accuracy
• Reduced reliance on conventional mechanical adjustment
• Greater flexibility during garment production

The machine supports a maximum stitch length of 5mm, according to the supplied technical specifications.

AUTOMATIC THREAD TRIMMING

The JACK A5E-B AMH2 features an integrated automatic thread trimming system, designed to improve sewing efficiency and reduce manual finishing work.

The system trims the sewing thread to approximately 3.5mm, helping minimise excess thread remaining after sewing.

This is particularly beneficial for garment manufacturing and production environments where operators perform repeated stitching operations throughout the working day.

Benefits include:

• Automatic thread cutting
• Approximately 3.5mm remaining thread length
• Reduced manual thread trimming
• Improved productivity
• Cleaner finishing
• Faster transitions between sewing operations

Actual remaining thread length may vary depending on the thread, material and machine setup.

SEMI-DRY HEAD LUBRICATION SYSTEM

The JACK A5E-B AMH2 incorporates a semi-dry head design to help minimise the risk of oil contamination during sewing.

Unlike conventional industrial lockstitch machines that supply oil to the needle bar drive mechanism, the semi-dry head design eliminates the oil supply to this area.

This helps reduce the possibility of oil reaching the sewing material.

Advantages include:

• Reduced risk of oil staining
• Cleaner sewing environment
• Improved protection for sensitive materials
• Reduced oil contamination around the needle bar mechanism
• Suitable for professional garment production

Please Note: Semi-dry head does not mean the entire sewing machine is oil-free. Other internal mechanisms may still require lubrication according to the manufacturer's instructions.

CONVENIENT NEEDLE-BAR FUNCTION BUTTONS

The JACK A5E-B features three convenient function buttons positioned near the needle bar, providing quick access to frequently used sewing functions.

These include:

1/2 Stitch Function: Allows precise needle positioning by moving the machine through half a stitch cycle.

Add Stitch Function: Enables the operator to insert an additional stitch when required.

Bartack Function: Provides convenient access to reverse stitching for reinforcing the beginning or end of a seam.

These controls help reduce unnecessary interruptions and allow operators to perform common adjustments without repeatedly accessing the main control panel.

USB CONNECTIVITY

The JACK A5E-B includes a USB connection port, providing connectivity for supported external devices and manufacturer-approved functions.

Available functionality depends on the machine's control system and manufacturer specifications.
