大阪染織機械株式会社 Company Overview

Drive device zero for wrinkles and shrinkage to be virtually zero! OS Expander Roll.

We are Osaka Senshoku Kikai Co., Ltd., the pioneer and first manufacturer to domestically produce "Expander Rolls" in Japan. We provide fundamental solutions to eliminate "wrinkles," "shrinkage," and "slippage" in Roll-to-Roll web handling processes for films, metal foils, and non-woven fabrics. [Our Core Strengths] ◆ Japan's Only "Precision Curved Grinding" Our unique technology enables precision grinding while the roll is in its curved state. This eliminates vibration even on high-speed lines for ultra-thin films, dramatically improving your production yield. ◆ Ultra-Low Torque "Drive-less Design" No motor required. Our rolls rotate smoothly driven solely by the web's conveying force, effectively preventing slip scratches on your products. ◆ "Special Materials" & "Retrofitting" Fully compatible with special materials such as "fluorine rubber" (FKM), which is essential for high-temperature and adhesive lines. We also have an extensive track record of replacing/retrofitting other manufacturers' flat-type rolls with our curved rolls. ◆ Repair & Refurbishment for All Brands We provide repair and restoration services for expander rolls from any manufacturer, both domestic and international. [Proven Track Record] Since our founding in 1951, our cutting-edge technology has been featured on major national TV news programs and exhibited at the Expo 2025 Osaka, Kansai. Beyond standard catalog specifications, we promise to offer the optimal proposals and solve your line's most difficult challenges. Please feel free to contact us.

Business Activities

EXP Business: Manufacturing, sales, and repair of OS expander rolls and various other expander rolls, rubber surface grinding processing. Teflon Business: Heat shrink processing and sales of fluororesin (Teflon) tubes. PVC Business: Manufacturing and sales of PVC straight rolls.

Why is our expander roll "expensive"? The real reason.

  • OTHER

"The wrinkles on site just won't come out..." To surely solve such concerns, we chose to compete not on "low prices," but on "overwhelming quality." Osaka Shomeki Kikai Co., Ltd.'s expander rolls are "expensive" compared to mass-produced products from other companies. This is because we do not create "standard products that are just made to take shape." We are committed to fully custom-made solutions that are designed from scratch to match the conditions of our customers' production line speeds, tension, materials, and more, ensuring that we effectively resolve any issues. Graduating from price competition, we uphold our pride as the first manufacturer in Japan to domestically produce expander rolls. We have written about the true reason why we continue to insist on "fair pricing" in our note. For all manufacturers who want to value their own technology, and for those who are genuinely troubled by wrinkles on site, please take a look at the related link. ▼ The true value of fully custom-made solutions for uncompromising sites (note article)

"Ultra-thin film" - Is the ambiguous notation of "under 45g" the cause of defects!? The ultimate low torque that focuses on numerical values.

  • OTHER

Wrinkles and slip marks that occur during the transport of thin films The cause may be the "variability in weight (individual differences)" of the rolls. The vague notation of "below XXg" found in general catalogs cannot meet the stringent demands of the field. That is why OSM imposes on itself the extremely strict range of [25g to 35g] (for specific sizes) and ensures that products are shipped within this range through meticulous adjustments by skilled craftsmen. Here lies the essence of completely custom-made products that allow for no compromise. The remarkable capabilities of the 'Super Small GD2 Type,' which reduces sheet slip to the absolute minimum, are currently available on our note! Check the related link.

【Second public release following the Osaka-Kansai Expo!】 The magic roll that smooths wrinkles, 'OS Expander Roll,' makes its appearance at the "Osaka Manufacturing Interesting Future Exhibition."

  • SEMINAR_EVENT

Osaka Dyeing and Weaving Machinery Co., Ltd. will exhibit the "OS Expander Roll" at the 33rd Skills Grand Prix concurrent event "Osaka's Manufacturing Interesting Future Exhibition" (hosted by Osaka City), which will be held from February 27. Our expander roll is an essential industrial roll for manufacturing that reliably eliminates "wrinkles" occurring in the production processes of films, paper, non-woven fabrics, and metal foils. Since it is usually integrated into BtoB production lines, there are very few opportunities for the general public to see it. However, at the "Osaka-Kansai Expo" held in September, its niche yet important role attracted a lot of interest and received a very positive response. This will be the much-anticipated second public exhibition following that event. 【Technology of "Osaka Dyeing and Weaving Machinery" Supporting Japan's Manufacturing】 We are a pioneering company that was the first in Japan to domestically produce expander rolls. Through our unique bending technology and precise processing techniques developed over many years, we have solved various "wrinkle" challenges for our customers.
