Description

Technical Field

[0001] The utility model relates to the technical field of card clothing, in particular to a long-life card clothing. Background Art

[0002] Card clothing: various carding machine parts covering with needles or teeth on the surface, which is one of the important parts of spinning. It is divided into two categories: elastic card clothing and hard card clothing. Elastic card clothing is made of base cloth and many combing needles planted on it. Hard card clothing includes needle plates with steel needles planted on wooden boards and metal card clothing similar to saw blades. After various types of card clothing are coated on the surface of the machine parts, they become a flat and sharp needle surface, which is used for combing fibers, and can also be used for loosening and removing impurities. Different types and specifications of card clothing can be selected according to different processing requirements of spinning raw materials. Metal card clothing is also called metal saw blade, which has a relatively long service life. Since the needle teeth and base of the card clothing are usually integrated, the entire card clothing needs to be replaced when the needle teeth are damaged, which increases the maintenance cost. Therefore, a long-life card clothing is proposed to reduce the maintenance cost. Utility Model Content
