Jack 7S-91-T
Computerized Post-Bed Machine with 4 Stepper Motors and Italian Touchscreen

The Jack 7S-91-T is a computerized post-bed machine with independent double roller feed, designed for high-end leather goods sewing: leather shoes, sports shoes, suitcases, bags, gloves, hats, and leather clothing. Its 4 independent stepper motors and 5-inch Italian touchscreen make it precise, versatile, and easy to use even for less experienced operators.

Key Technologies

• 4 Independent Stepper Motors — main motor + needle bar for needle tip feed + 2 motors on the rollers with adjustable differential: more accurate, faster, and quieter sewing
• 5-inch Touchscreen in Italian — adjust speed, stitch length, sewing mode, and advanced parameters with a touch
• Silent Backtack — controlled by a stepper motor, faster and quieter than traditional mechanical systems
• High Perforation Capacity — penetrates over 110 sheets of A4 paper, suitable for ultra-heavy fabrics of work shoes
• Ultraviolet Light + Dimmable LED — UV light increases the visibility of the drawn line for more precise seams

Operating Features

• Quick Stitch Length Change Button — change the length with a pre-set click at turns and corners
• Extendable Backtack Lever — double extendable layer, manageable with the arm during sewing without interrupting work
• Roller Pressure Adjustment — via top screw for quick and precise adaptation to the material
• Flip-up Guide — maintains constant distance from seams and prevents thread slack in tight spots and corners
• Self-cooling Handwheel — fan structure that keeps internal components ~4°C cooler, extending machine life
• Ornamental Stitch Patterns — programming different stitch lengths and customized repetitions

Versions and Optional Features

• Short Cut X — thread cut to just 3 mm, no manual trimming
• Bobbin End Detection — automatic stop when less than 30 cm of thread remains in the bobbin (optional)
• Narrow Column S7-81CX-T — subclass for bottom seams, side parts, and tight corners (bags, children's shoes, boots)
