Roll production suction roll
The rolls widely used in film and sheet extruders, slitters, stretchers, coater machines, and paper-related machinery are very precise industrial components despite their simple appearance. At Otec, we can manufacture and process rolls for all applications and precision levels, leveraging our technology backed by years of experience.
Numerous delivery achievements of converting machine rolls! Contributing to high-precision coating.
The coater roll is a roll that plays the role of applying coating liquid to the substrate in reverse coaters such as coating rolls, application rolls, and metering rolls. The thickness of the coating film is adjusted by the rotation speed of the roll and the gap between the rolls, and high precision is required for the roundness, cylindrical shape, and runout during rotation to achieve a thin and uniform coating. Despite their simple appearance, rolls are highly precise industrial components. As the required precision for rolls becomes more advanced, the processing becomes more difficult, and you may have experienced cases where the delivered rolls did not meet the required precision. At Otec, we can manufacture and process high-precision rolls with roundness, cylindrical shape, and runout of less than 3 microns, thanks to our many years of experience. We can also reproduce the ideal surface roughness according to customer requests. We provide inspection reports (runout charts, roughness data) and conduct on-site inspections. Additionally, we can also perform polishing with bearings installed upon request. Please contact us for more details.

An expander roll that rotates with a small torque, minimizing the impact on the film.
An expander roll is a bow-shaped curved roll used to remove wrinkles and shrinkage that occur during the manufacturing process of sheet products such as film, paper, non-woven fabric, and metal foil. The low-torque expander roll rotates with minimal torque, thereby minimizing its impact on the film. It is energy-efficient as it does not require a drive and is ideal for thin films and metal foils of a few micrometers. 【Features】 ○ Rotates with low torque ○ Minimal impact on the film ○ Energy-efficient with no drive required ○ Ideal for soft films where minimal load is desired or when there is no space for a drive installation due to design constraints For more details, please contact us or download the catalog.
Durable and excellent in runout accuracy, the expander roll is resistant to dirt and easy to clean.
An expander roll is a bow-shaped curved roll used to remove wrinkles and shrinkage that occur during the manufacturing process of sheet products such as film, paper, non-woven fabric, and metal foil. Steel expander rolls are excellent in durability and runout accuracy. They are less likely to attract debris compared to rubber rolls, making them easy to clean. 【Features】 - Various materials such as iron, stainless steel, and aluminum can be selected - Grooving on the surface is also possible - Excellent durability and runout accuracy - Ideal for situations where wear and foreign matter are concerns with rubber rolls, or when cleaning and maintenance are troublesome For more details, please contact us or download the catalog.
Teflon heat shrink tubing can be coated! A roll that does not cause sagging.
The "Rubber Expander Roll" is designed to operate without causing damage to the front and back of the substrate due to friction or slipping while in motion, completely removing wrinkles and shrinkage, and allowing for the widening of the substrate as needed. Compared to flat expanders, it has a smaller rotational torque, enabling uniform widening even at high speeds. We also offer a low-torque version that reduces rotational torque by 50% compared to standard products. 【Features】 ○ Various synthetic rubber materials can be produced according to application (conductive, chemical-resistant, water-resistant, oil-resistant, heat-resistant, corrosion-resistant, etc.) ○ Compatible with soft rubber (sponge rubber) ○ Special ball bearings suitable for use in cleaning tanks are also available. For more details, please contact us or download the catalog.
Realizing labor-saving and non-driven! Low torque expander roll.
The "Rubber Expander Roll for Underwater Use" is made from rubber materials that consider water resistance and chemical resistance. It is possible to attach a pulley for power transmission. 【Features】 ○ Eliminates wrinkles and shrinkage that occur during the manufacturing process of sheet products such as films, paper, non-woven fabrics, and metal foils. ○ A structure arranged with multiple spools that have ball bearings built into a curved shaft. ○ Does not cause damage to the front and back of the substrate due to friction or slipping while in operation. For more details, please contact us or download the catalog.
Minimal impact on the film! Rolls that turn even with low torque.
The "Rubber Expander Roll - Low Torque" rotates with a small torque, minimizing its impact on the film. It is energy-saving as it does not require a drive. 【Features】 ○ Eliminates wrinkles and shrinkage that occur during the manufacturing process of sheet-like products such as film, paper, non-woven fabric, and metal foil. ○ A structure arranged with multiple spools that have ball bearings built into a curved shaft. ○ Does not cause damage to the front and back of the substrate due to friction or slipping while in operation. For more details, please contact us or download the catalog.
Ideal for high-speed operation! The expander roll has excellent rotational accuracy.
The "Steel Expander Roll" uses stainless steel for the spool, offering excellent corrosion resistance, and since the roll surface is metal, its lifespan is improved compared to rubber expanders. 【Features】 ○ Various metal surface treatments are possible ○ Excellent wear resistance, chemical resistance, and heat resistance ○ Special processing such as groove machining on the roll surface is also possible For more details, please contact us or download the catalog.
Achieving higher line speed and production efficiency! Lightweight expander roll.

The black pearl ceramic coating achieves both uniform adhesion and a reduction in adhesive usage at the same time!
The Black Pearl Ceramic Coating is a patented technology that overturns the conventional thinking of ceramic anilox. The core technology of this coating process has been uniquely designed and improved by CAE, resulting in an automated robotic system that integrates ceramic thermal spraying and the BPCC process. This has enabled the high reproducibility of cell patterns created by laser engraving, independent of the skill level of the ceramic thermal spraying operator. To ensure reliable adhesion, it is necessary to manufacture the axis runout (T.I.R.) and outer diameter (O.D.) of both the gluing roll and the doctor roll within tolerances. This ensures the most stable and narrowest gap tolerances possible, reducing the amount of starch adhesive used while achieving the required adhesion strength. Manufactured with the most stringent T.I.R. and O.D., the high-performance glue set consists of doctor rolls and gluing rolls made with a unique black Black Pearl mirror-finished ceramic coating, enabling high yield, increased production speed, reduced starch adhesive consumption, ease of cleaning, high reproducibility, and extended roll lifespan.
