AI-based Online VISION SYSTEM for guided sewing ensures the control and optimization of the seam pattern between the perforation (when topstitching of decorative seam designs on fully and partially perforated leather and fabric). The Clou, AI Online Vision System ensures the control and optimization of the seam appearance between the perforation in REAL TIME and STITCH BY STITCH. Position tolerances of the perforation are detected and corrected immediately. Maximum quality results can thus be achieved. Waste is permanently minimized. This saves time and money and makes an important contribution to sustainability. Revolutionary!
