Automatic Thread Trimmer
Equipped with photocells, the electronic trimmer automatically activates at the start and/or end of the seam, ensuring a clean finish without manual intervention.
Automatic Presser Foot Lifter
Electronically controlled, the presser foot automatically lifts before and/or after sewing via built-in photocells, boosting efficiency and simplifying operation.
Acceleration and Deceleration
Increased responsiveness with 14.3% faster reaction time: acceleration from 0 to 5,500 rpm in just 100 ms and deceleration to zero in 180 ms for precise and efficient control.
Three Sewing Modes
Choose from three flexible operation modes:
• Manual: Full control via pedal.
• Semi-automatic: Pedal for sewing, automatic thread trimming and presser foot lift via photo sensors.
• Automatic: Fully controlled by photocells (no pedal required).
• Manual: Full control via pedal.
• Semi-automatic: Pedal for sewing, automatic thread trimming and presser foot lift via photo sensors.
• Automatic: Fully controlled by photocells (no pedal required).
Wide Adaptability
The dual feed system significantly improves fabric feeding, allowing stable and easy sewing of dense multi-layer materials without creases.
Mesh Fabric Mode
Prevents false triggers when sewing thin or transparent fabrics such as tulle or organza by disabling photocell activation until tight contact with the fabric is detected.
Short Thread Trimming
The automatic electric trimmer via photo sensors precisely trims the thread (8 mm in front and 5 mm in the back), minimizing waste and replacing manual trimming.
Industry 4.0
Thanks to the built-in Wi-Fi module, you can remotely configure equipment parameters and monitor performance via the app. Note: One Jack Gateway is required for every 50 machines.
Jack C5T-5-A04/435 is a high-speed computerized 5-thread overlock with built-in differential feed (walking foot / top feed), designed specifically for heavy-weight materials (denim). Engineered for maximum reliability, durability, and ease of operation. It provides unmatched fabric pulling power, effectively preventing layer shifting in dense and heavy materials, while the built-in servomotor guarantees smooth, precise, and energy-efficient sewing.
