The floating unwinder of the
stretcher leveler unwinds in the upper unwinding mode. The unwinding machine is powered and actively unwinds, with adjustable tension in the unwinding section. Its structure is a floating single cantilever, which consists of a reel, a reduction box, a floating base, a clamping roller, a support arm, a driving power source, a hydraulic cylinder for expansion and contraction, a rotary joint, a brake, and other main components. The strip steel realizes the plate straightening function through two bends and two straightening machines. The
plate leveller has two control modes: elongation and tension.
Tension straightening is a straightening process that is composed of a stretching flange roller and a bending material overlapping on the straightening roller. The combination of the two processes of stretching and bending enables the
tension leveler to achieve a higher level of plasticization.
