Key Components

Safely enclosed, J71 AP adult pant machine integrate:

  • Threading System: Automated multipurpose threaders reduce setup times between styles.
  • Robotic Arms: Precisely maneuver and position fabric via synchronized articulating joints.
  • Ultrasonic Technology: Non-piercing ultrasonic sealing bars finish hems and seams.
  • Laser Guidance: Positioning lasers ensure accurate replication of digitized patterns.
  • Touchscreens: Intuitive controls enable complete programming and operation by one operator.

Operation Process

Fully digital pattern chains optimize sewing cycles down to individual stitch pitches:

  • Robotic arms lay fabric panels perfectly aligned via laser guidance.
  • A servo feed system tensions fabric for even feeding through processes.
  • An electronic sewing head precisely stitches programmed seam designs at high speeds.
  • Additional seaming operations progress fabric around the machine.
  • Cameras inspect for defects allowing early quality intervention.
  • Finished pants exit on a Conveyor for pressing, finishing and packaging.

Production Flexibility

Juki AP machines deftly manufacture styles from basic jeans to technical fits with four-way stretch fabrics. Customizable sewing patterns adapt designs seasonally via online database updates without machine modifications. Changing between fabrics takes only minutes, minimizing costly setup adjustments.
