The HWSY Series Straightener includes a range of models equipped with a handwheel-operated opening mechanism, where the upper and lower rows of rollers close symmetrically around the product by turning the handwheel. This symmetrical movement maintains a constant centerline, even when changing the diameter of the product. The series is further divided based on the size of the straightening rollers.
