Even with guides that have the same surface finish, the quality can vary by manufacturer, so it is necessary to discern between them. Although guides with nearly the same shape and surface finish (matte finish) may appear indistinguishable at first glance, comparing their surfaces under an electron microscope reveals differences in crystal size. Smaller crystals result in higher friction resistance from the start, which can easily damage the line, while larger crystals have less friction resistance and are less likely to cause damage to the line. It is important to choose products from manufacturers with assured quality, even among the same type of guides. *For more detailed information, please refer to the related links.

When producing chemical fibers, two important products that influence their quality are the "Oiling Guide" and "Migration." The "Oiling Guide" is a functional guide used in the spinning process of synthetic fibers that applies oil agents to prevent static electricity and to dye the yarn and fabric uniformly. "Migration" is a device that disperses the oil applied to the yarn using the Oiling Guide more evenly by ejecting compressed air from a nozzle. To minimize damage, it is crucial to select a guide with a surface treatment suitable for the yarn. For example, in the case of flat yarn, a mirror finish results in a larger contact area and greater friction on the yarn, whereas a pearlescent finish reduces the contact area and minimizes friction on the yarn. *For more detailed information, please refer to the related links.

Here are some points to consider when using the "Storage Tensioner," which achieves stable tension through arm movement. By changing specifications such as the difference in total length, reducing the number of bars to alter the bending angle, or adjusting the thickness of the built-in spring's linearity, it is possible to change the tension. By modifying specifications or changing the wire diameter of the spring, you can achieve the tension that suits your company. Additionally, the eyelet guide through which the thread passes is made of ceramic, and you can choose the surface treatment between standard and mirror finish. For example, a mirror finish can reduce friction for twisted threads. You can also change the orientation in which the eyelet guide is installed. [Points to Consider When Using] ■ Choose specifications that match the desired tension ■ Surface treatment and installation orientation of the eyelet guide *For more details, please refer to the related links or feel free to contact us.

We will introduce a case where we developed a new product with a consistent system from sales, design, to processing, which increased the detection speed of thread breaks and improved productivity. We received an inquiry about whether we could detect thread breaks faster using the N810004-L05/R05 stopper. If we can detect them more quickly, the risk of weaving with a broken thread decreases, leading to improved quality stability and work efficiency. After thorough consideration, we decided to create a new product using an improved mold for the plate and to mass-produce it, which would lower the cost per unit. By verifying the movement of the conductive plate on a computer and calculating the details, we were able to create a conductive plate with the desired performance, much to the satisfaction of our customer. [Challenges] - We want to detect thread breaks within the range before the wire guide drops. - Improving the plate requires creating a new mold, which incurs significant costs. *For more details, please refer to the related links or feel free to contact us.*

We would like to introduce a case where the customization of a stopper installed on the creel of a weaving machine has increased the types of yarn that can be handled. Using the N810004-L05/R05 stopper, we previously used three types of yarn. However, when processing particularly thick and strong yarns like 1000D, there was an issue where the stopper would not operate and would fall over during yarn breakage. After two weeks of careful consideration, we re-designed the shape of the wire to make it more prone to falling over, taking into account the characteristics of the equipment and the yarns used in that specific environment. As a result, we successfully enabled the detection of yarn breakage for 1000D yarn. [Challenges] - We want to apply it to several types of yarn as the yarn changes depending on the production item. - Particularly when processing thick and strong yarns like 1000D, the stopper does not operate and falls over during yarn breakage. - The wire guide is lighter than the yarn, and even if the yarn breaks, the yarn remains taut on the wire guide. *For more details, please refer to the related links or feel free to contact us.
