Bow-shaped curved roll, vari-bow expander roll, conical type.

Reverse crown flat curve, a conical type that allows for three shapes with one piece.

An expander roll is a bow-shaped curved roll used to remove wrinkles and shrinkage that occur during the manufacturing process of sheet products such as film, paper, non-woven fabric, and metal foil. The Vari-Bow is a type that allows for adjustment of the bow (curvature) during operation. The Vari-Bow Expander Roll Conical Type can adjust excessive widening in the center and slack at the ends by changing its shape. By obtaining widening force from the difference in roll diameter between the center and the ends, it minimizes the amount of curvature and reduces the effects of friction and slip. 【Features】 ○ Capable of three shapes: reverse crown, flat, and curve, all in one roll ○ Adjustable excessive widening in the center and slack at the ends ○ Reduces the amount of curvature and minimizes the effects of friction and slip ○ Ideal for situations where you want to minimize the impact on the film before winding or when the shape of the curvature is a concern For more details, please contact us or download the catalog.

OS Variable Bow Expander Roll (Manual Type)

OS Variable Bow Expander Roll (Manual Type)

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.
