Bow Banana Roller


Bowed rollers (also known as banana rollers) are used in the paper, film, foil, and textile industries to uniformly spread the web material to eliminate creases or wrinkles. In slitting operations, these rollers are used to prevent interweaving of material. These rollers are used mostly in the manufacturing processes which produce a continuous web or substrate & need to be guided without wrinkles. These bow rollers can operate at any place and conditions, including in dry and wet environments, including plastic film, textiles, paper manufacturing, or the various converting industries.

Bow Banana Roller formation at any stage of manufacturing or processing is inevitable. To prevent inferior quality and/or rejection of webs, wrinkles must be removed at all necessary stages.  Most of the expander rolls are driven by web tension itself without any extra drive. These are used in textile processing machines, plastic converting machines, paper industries, in manufacturing, processing, printing, laminating, coating, batching, winding and re-winding. Further, our range is quality tested in order to make sure that these meet the international industrial standards.
