Shed formation in special areas
High warp tensions and densities, high fabric complexity, and changing pattern structures and shed parameters are all fields of application for the UNIVAL 500T. This servo-controlled dobby allows individual shed opening, pick for pick, giving you an ideal tool for producing technical fabric – and to explore and develop new kinds of fabrics with innovative properties. The UNIVAL 500T features a modular design and can be expanded to drive up to 56 heald frames.

The Unival 500T mounted on a weaving machine for PMC (Paper Machine Clothing) using 12 to 18 heald frames produces heavy and wide technical fabric. In such applications, warp tension can reach up to 60 tons, requiring (depending on shed geometry) extremely high lifting forces for each heald frame, which must be handled by the UNIVAL 500T’s servo motors.
