본딩용 압축 롤 균압 향상을 위한 연구 = A Study on the Improvement of Pressure Distribution of Bonding Roll

다국어 초록 (Multilingual Abstract)

This is a study to improve the evenness of distribution of bonding rolls used in fabric finishing process. Bonding rolls being produced domestically have uneven pressure distribution in longitudinal direction. The pressure at the both ends of rolls are greater than that at the center. So, to ensure the uniform pressure distribution, they manufacture silicon coating of rolls with tapered shape: so called crown. But, the silicon coating is needed to be machined periodically, since it is worn out during operation. Therefore to avoid additional machining of silicon coating, optimal roll structure has been sought to make uniform pressure distribution on the roll surface. Existing roll structure has been changed with new design. Design has been performed for existing three kind of the bonding roll through finite elements structure analysis. By using the design data a company has manufactured bonding rolls installed at a multi functional finishing machine.
