Details :

  • Bow roll is the commonly used wrinkle removing roller. Belmark is a pioneer in manufacturing and supply of bow rollers, which are also referred to as Expander Rollers, Banana Roll, Slat Expander roll, Spreader roll, Scroll Roll, Wrinkle Removing Roll etc.
  • These rolls are supplied with mounting brackets, which could be either wall mounting or foot mounting. The bow Expander Rolls consist of bowed shafts, sealed ball bearings, abrasion resistant sleeve and metal segments. These are widely used as wrinkle removing devices in various industries and are available in various dimensions. The rolls are also supplied with gear box and mounting brackets which can either be Foot Mounted or Wall Mounted. 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 per 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 in proper warp angle with web material. To make such warp angle adjustment 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 make any change in the bow setting bow warp angle with web materials is set. On shaft bow position is indicated by 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 also 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, processing, printing, laminating, coating, batching, winding and re-winding.
  • 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 Rolls having heavy weight and paper tension itself is not sufficient to drive the Roll. So extra pulley is provided to drive the metal bowed Roll.
  • Teflon Expander roll is particularly used before size press where wet working condition and extra drive is required to get the roll rotate. Teflon rubber bow roll is used for application where sticking of substance on the roll is a problem.
