Innovating the quality of high-load lines with hydraulic control that balances power and precision.
【Product Features】 • Powerful and stable curvature adjustment through hydraulic control By utilizing a hydraulic cylinder, it provides greater adjustment force than manual systems. It enables powerful and stable curvature (bow) adjustments even for wide and high-tension sheets. • Adjustable for optimal wrinkle removal effect even during operation Similar to manual systems, the degree of curvature can be adjusted without stopping the equipment. It responds instantly to changes in sheet condition and operating circumstances, maintaining the highest quality at all times. • Versatile dual-functionality as a straight roll By setting the degree of curvature (bow) to zero, it also functions as a complete straight roll. It performs various roles with a single unit, enhancing the versatility of the equipment.
