Bow Rolls are available in rubber surface, hard chrome surface and also Teflon covering for non-sticking applications. Hard chrome surface Bowed Roller is used where speed is more than 300 meters minutes. If the speed is more, the bigger diameter is used to reduce the rpm of the roll. 
Bow roll works only when there is proper lead-in and lead-out distance and kept the roll in proper warp angle with web material. To do such warp angle adjusting all rolls are supplied with bow angle adjusting worm-worm wheel gearbox with hand wheel and counter pedestal bearing block. By use of this it is possible to adjust the bow angle at 360 degree warp angle. When the Roll get maximum wrinkle removing, stop the bow angle adjusting and put the roll on bow locked position. Do not do any change in the bow setting bow warp angle with web materials is set. On shaft bow position indicated an arrow showing the bowed position of the Roll. Metal expander with hard chrome plated surface is used for high speed application. Teflon sleeve is used for non-sticking application. Bow Rolls are known as useful for removing of wrinkles, slack edges, spreading and slit separation. 
Most of the Bow Expander Rolls are driven by web tension itself without any extra drive. Used in Textile processing machines, Plastic converting machines, Paper Industries, in manufacturing, processing, printing, laminating, coating, batching, winding and re-winding. Bow Roll is available foot mounting type & flange mounting type. We are rated among the topmost Bowed Roller Manufacturer in India. 
Bow angle adjusting worm-worm wheel gear box with hand wheel Metal is used for before high-speed Paper slitter re-winders for wrinkle removing and after slitting to separate slits. Big diameter Roll having heavy weights and paper tension itself not sufficient to drive the Roll so extra pulley is provided to drive the metal bowed Roll. Teflon Expander is particularly used before size press where wet working and extra drive is required for to get roll rotate. Teflon rubber bow roll having application where sticking of substance on roll is problem. We have positioned ourselves as one of the major Bow Rubber Expander Roll Exporters in India.
