The Inspection Rewinding Machine is equipped with a shaftless independent hydraulic unwinding unit, professionally built for surface inspection and precision rewinding of various labels, general flexible packaging films, food-grade flexible packaging materials and consumer goods packaging substrates. The shaftless hydraulic unwinding design of inspection rewinder enables convenient loading of heavy jumbo rolls without time-consuming shaft penetration, greatly reducing labor intensity and roll loading time. During the rewinding process, operators can visually check printing deviations, ink missing, scratches, pinholes, wrinkles and other surface defects in real time, marking defective positions for subsequent rejection to upgrade final product quality.
