Automatic cut & sewing process

Описание: 1. Automatic Cutting Process

🔹 Purpose:

To cut fabric layers accurately according to pattern shapes before sewing.

🔹 Main Steps:

1. Fabric Spreading:

Fabric is spread layer by layer automatically using a spreading machine.

The system ensures even tension, alignment, and no wrinkles.



2. CAD Pattern Input:

Patterns are created using CAD (Computer-Aided Design) software.

The cutting marker is generated to minimize fabric waste.



3. Automatic Cutting:

CNC (Computer Numerical Control) cutting machines or Auto-cutters (Gerber, Lectra, Bullmer, FK Group) are used.

Uses vacuum suction to hold layers tight during cutting.

Cuts multiple layers simultaneously using knife, laser, or water jet.

Output: Precisely cut garment pieces labeled and bundled by size/style.




🔹 Advantages:

High cutting accuracy (±1 mm)

Saves time and fabric

Reduces manpower

Consistent quality

🪡 2. Automatic Sewing Process

🔹 Purpose:

To stitch garment parts automatically with minimal human intervention.

🔹 Types of Automatic Sewing Machines:

1. Pattern Sewing Machines

Used for pocket attachment, label sewing, or bar tacking.

Example: Brother BAS series, Juki AMS series.



2. Automatic Seam Machines

Specialized for collar, cuff, waistband, or placket joining.



3. Overlock & Flatlock Automation

Automatically feed fabric and trim edges for knit garments.



4. Button & Buttonhole Machines

Fully automated – place, sew, and cut thread automatically.



5. Unit Production System (UPS) or Conveyor Sewing Lines

Garment parts move automatically through each operation station via conveyor.




🔹 Integrated Technology:

PLC/Computer Controlled operation.

Sensors detect fabric position & seam end.

Robotic arms for folding, aligning, or feeding.

Vision systems (AI cameras) for seam accuracy checking.


🔹 Advantages:

Higher production speed (up to 2–3× manual)

Consistent seam quality

Lower skill dependency

Reduced defect rate

Real-time data tracking for quality & efficiency
