Pin wheels automatic weftstraightener for woven fabrics. It uses a simple and effective physical principle: the weft threads, subjected to tension, return to their original and orthogonal structure’s condition.
Classic weftstraightener for adjusting bow and skew distorsions on knitted and woven fabrics,contolled by a “LECTRON” optical-electronic system, which detects the fabric’s structure and drives the rollers.
The top of the weftstraighteners. A new device that combines, in a synergetic way, pin wheels system and bow-skew rollers with photo-electronic control system. It follows an extremely and complete machine, that is able to control, to ensure and to attest a perfect straight weft.
