Adjusting 'optimal' on the spot. Maximizing the potential of every seat.
【Product Features】 • Powerful and stable curvature adjustment through hydraulic control The size of the curvature (bow) can be adjusted freely using manual handle operation. Depending on the material and thickness of the sheet and the operating speed of the machine, it can be set in real-time for optimal wrinkle removal effect without stopping operation. • Versatile dual-functionality as a straight roll By reducing the degree of curvature (bow) to zero, it also functions as a complete straight roll. This allows one machine to perform various roles, enhancing the versatility of the equipment. • Available in ultra-low torque (MT) type for low-tension materials For customers handling delicate films that are sensitive to tension, we also accept orders for production in ultra-low torque (MT) specifications, which have extremely low rotational resistance.
