Bow Expander Roller

AstroRoll' s Bowed Rollers utilize a stationary curved axle fitted with a series of precision bearings and a flexible outer sleeve. As your web travels over the convex (bowed) surface, it is gently but firmly stretched outward from the center to the edges. This cross-machine tension instantly eliminates longitudinal wrinkles and baggy edges before critical processes like nip rolling, coating, or printing.
