大阪染織機械 List of Products and Services

This is an expander roll that complies with the "RoHS Directive" and is "free of crystalline silica," designed to meet strict environmental regulations. It is a completely custom-made model tailored to your specifications to meet special environmental standards that are difficult to address with standard catalog products. 【Do you have any of these concerns?】 - The current rubber roll can no longer be used due to new environmental standards. - A certificate compliant with the RoHS Directive (10 substances) has become necessary. - From the perspective of occupational health and safety, you are looking for products that do not contain crystalline silica. 【Features】 1. Environmental Compliance: We select and formulate rubber materials that do not contain the requested regulated substances. 2. Performance Maintenance: Even with environmentally compliant materials, the original "powerful wrinkle removal performance" and "durability" of OS expander rolls remain intact. 3. Flexible Response: We design and manufacture to match existing machines in terms of size, shaft shape, and more. We accept inquiries regarding whether a substance is included and consultations on material selection. Please contact us through "Inquiries" first.

The pioneer of expander rolls, Osaka Textile Machinery, has developed the "Outer Wheel Rotating Type OS Rubber Straight Roll." Unlike conventional iron core direct-wound rolls, it adopts a unique structure where "the shaft is fixed and only the rubber sleeve (outer wheel) rotates." Internal bearings reduce rotational resistance to the limit. It smoothly "follows" the sheet's conveying force without the need for a motor or other driving devices. It is ideal for preventing "scratches" and "slips" in high-performance films, non-woven fabrics, and paper processing lines that are sensitive to tension. **Features** Incredible low torque performance: It rotates smoothly even with weak tension, minimizing the load on the product. Easy installation and replacement: Simply fix the shaft. No need for motors, complex bearing designs, or electrical work. Replacing existing lines or adding test lines is easy. Functional surface processing: Grooving (helical or parallel) and polishing can adjust grip and air release properties. Adaptable to harsh environments: Material selection such as fluororubber and corrosion-resistant specifications can be produced for acid-based chemical lines and special environments. Emergency response service: For φ100mm (EPDM) specifications, we have established a rapid delivery system that can ship within 3 to 5 days at the shortest.

【Product Features】 Excellent chemical resistance for stable operation in harsh environments The entire roll is made of polyvinyl chloride (PVC), providing high resistance to chemical substances, including inorganic acids. This prevents corrosion and degradation, ensuring stable operation of production lines in harsh environments. Coating processing for existing metal rolls is also available It is possible to coat the metal rolls currently in use by customers with polyvinyl chloride (PVC). This allows for easy enhancement of chemical resistance and durability while utilizing existing equipment. Optimal surface precision polishing tailored to applications Depending on the products handled by customers and the conditions of the production line, precision polishing of the surface can also be performed. Leveraging years of expertise, we propose the optimal specifications to solve customers' challenges.

【Product Features】 • Excellent wear resistance that withstands high tension and high load environments The surface is coated with highly wear-resistant urethane rubber. With a tough design that supports a maximum tension of 9000 kgf, it minimizes wear even in high-load production lines such as steel plates and metal foils, ensuring stable operation over a long period. • Ideal for manufacturing lines of steel plates and metal foils Its outstanding durability is particularly effective for wrinkle removal of sheet products that exert significant load on rolls, such as steel plates and thick metal foils. It achieves reliable quality even under harsh conditions. • Groove processing option to further enhance grip performance It is also possible to apply groove processing to the urethane rubber surface according to the characteristics of the products handled by customers. This improves grip performance and meets the needs of customers seeking more reliable wrinkle removal effects.

• Rubber Processing Machine

【Product Features】 • Powerful and stable curvature adjustment through hydraulic control By utilizing a hydraulic cylinder, it provides greater adjustment force than manual systems. It enables powerful and stable curvature (bow) adjustments even for wide and high-tension sheets. • Adjustable for optimal wrinkle removal effect even during operation Similar to manual systems, the degree of curvature can be adjusted without stopping the equipment. It responds instantly to changes in sheet condition and operating circumstances, maintaining the highest quality at all times. • Versatile dual-functionality as a straight roll By setting the degree of curvature (bow) to zero, it also functions as a complete straight roll. It performs various roles with a single unit, enhancing the versatility of the equipment.

【Product Features】 • Space-saving design with built-in adjustment mechanism By incorporating the curvature (bow) adjustment mechanism inside the roll, we have achieved significant compactness compared to conventional models. It can be installed in narrow spaces that were previously difficult, such as the inside of machine frames. • Adjustable for optimal wrinkle removal effect even during operation Despite its compact size, it allows for adjustment of the curvature degree without stopping the operation of the equipment, just like other bow rolls. With optimal settings according to the condition of the sheet, it consistently maintains the highest quality. • Ultra-low torque (MT) type available for low-tension materials For customers handling delicate films that are sensitive to tension, we also offer production in an ultra-low torque (MT) specification with extremely low rotational resistance.

【Product Features】 • Excellent non-stick properties to prevent adhesion to roll surfaces The superior non-stick and slippery properties of fluororesin (Teflon) are applied to the rolls. This prevents the adhesion of adhesives, inks, and debris, significantly reducing cleaning efforts and improving productivity. • Wide compatibility from expanders to specially shaped rolls Our expander rolls can be coated, and we can also process special shaped rolls such as metal rolls and crown rolls used by our customers. This enhances the performance of various rolls. • Conductive types available for effective static electricity countermeasures We also offer conductive type tubes that suppress static electricity, which can be a problem in film and paper production lines. This helps prevent dust adhesion to products and reduces the risk of electric shocks.
