Expander Bars- Bow Rolls are known as Banana Rolls, Spreader Rolls, Curve rubber expander, useful for removing of wrinkles, slack edges, spreading and slit separation. Most of the 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.
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.
Bow Roll is available foot mounting type & flange mounting type. We also provide perfect customization for specific operations. Bow roller positioned perpendicular to the web direction give best result.

Special FeaturesRotary Joint, Shaft With Inside Hole
Cooling Roller comes with a hard chrome plated surface & Rubber coated roller. Cooled water passing through its Rotary joint cools the hard chrome plated surface area of the Roll. Standard Cooling Roll cools the contact area that touches the web materials. There are different types of Cooling Rolls like single shell, double shell jacketed type, spiral type. The Surface Cooling Roller results in varying effects in different type of Cooling Rolls. Rotary Cooling Roller has a shaft with inside hole to fix rotary joint. Bigger shaft diameter is recommended to avoid breakage of end shafts as end shaft having inside hole and uneven alignment or heavy tension on shaft result brakeage so bigger shaft diameter is recommended. We are called upon as one of the major Industrial Cooling Roller Manufacturers in Gujarat(india).

Polytech’s Air Shafts (Expanding) are expanded immediately under air pressure for instant roll mounting and gripping securely and fast without damage to the core or roll. Moreover, at the touch of the fingers (keys, lugs etc.) between shaft and core, they collapse positively for quick roll removal. The shafts consist of three basic parts - a metal body cast in tough, durable, steel or aluminum alloy, an uniquely elastomeric air expanding element & Dimensional tolerance of journal is very tight for better fitting & rigidity during operation. Simplicity and high reliability of shaft design, and high tension strength-to- weight ratio assure rugged, reliable performance with minimum maintenance in excellent economy and ease of operation.
All Polytech's air (expanding) customized (OEM and ODM) shafts (Button, Key, Lug, Leaf types) are our custom manufactured to your specifications. And standardized components facilitate quick, cost-effective construction and replacement .
