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.
