[Achievements] Osaka Dyeing and Weaving Machinery Co., Ltd. OS Expander Roll Installation Case
Please take a look at some examples of how our expert technology, cultivated over more than 70 years, has helped customers solve various wrinkle and shrinkage-related problems.
Improves wrinkles in glass fiber fabrics!
フラットエキスパンダーロールでは解決できなかったガラス繊維織物の「折れジワ」の壁
駆動装置不要で難題を解決したOSMT低トルクロール
To solve the problem of wrinkles, the customer turned their attention to our low-torque OSMT expander roll.
The biggest deciding factor in introducing this roll was that it "does not require a drive unit." Conventional rolls could not solve this problem because the rotational resistance of the roll itself, even though slight, placed an unnecessary load on the transported fabric. The OSMT roll operates with extremely low rotational torque, so it does not apply unnecessary friction or tension to the delicate glass fiber fabric, and is able to rotate and spread smoothly using only the natural tension of the fabric.
【導入後の結果】
Without adding any special drive devices or complicated controls, simply installing the OSMT expander roll dramatically improved the creases in a specific glass fiber fabric that had previously been difficult to resolve. This eliminated the need for labor on the winding line and enabled the stable production of high-quality products without slowing down production speed.
Eliminate product loss caused by wrinkles inside the drying oven!
A revolutionary heat-resistant expander roll that overcomes problems caused by thermal expansion
Wrinkles were forming on textile products in drying ovens with a maximum ambient temperature of approximately °C, resulting in product loss. With conventional heat-resistant rolls, simply changing the bearing grease or making the rubber material more heat-resistant was not enough, as problems occurred due to the rubber's expansion and contraction caused by thermal expansion. Therefore, the lack of a heat-resistant roll that could be directly installed in the drying oven was a major problem.
[Introduction of Osaka Dyeing and Weaving Machinery's expander roll]
To address this issue, we proposed a revolutionary heat-resistant expander roll that fundamentally improved the problems caused by thermal expansion. It controls the movement of thermal expansion even in high-temperature environments of approximately 200°C, achieving a structure that is less likely to cause problems. It is a unique product that can be directly installed in a drying oven.
[Improvement example]
By installing our heat-resistant expander roll directly into the drying oven, we were able to solve the long-standing problem of wrinkles in fabric products. This dramatically reduced product loss in the drying oven, enabling stable production of high-quality products.
