industrial needle roller

What is a needle roller?

Industrial needle roller is a kind of precision mechanical parts widely used in textile, non-woven, leather, papermaking, printing and other industries. It is mainly made of metal (such as steel, alloy) or engineering plastics, and its surface is evenly arranged with fine needle teeth or needles. Its core function is to process materials through the puncture, combing, pulling and other actions of the needle teeth.

Main types:

• Card rollers: used in textile and nonwoven industries to loosen and comb fibers (such as flat needle clothing, doffer needle clothing).
• Needle rollers: key components in nonwoven production, which entangle and reinforce fibers by puncturing up and down (such as needle plates for needle looms).
• Printing rollers: used in the printing industry to transfer ink or emboss, and the needle teeth form specific patterns.
• Cleaning rollers: remove impurities or residual fibers from the surface of the equipment (such as papermaking blanket cleaning rollers).

Core functions:

• Fiber processing: combing, sorting, and blending fibers to affect yarn uniformity and fabric strength.
• Material reinforcement: consolidating loose fibers into non-woven fabrics through a needle punching process.
• Surface processing: embossing, punching, or polishing the surface of leather or paper.
• Precision control: high-precision needle rollers ensure consistency in processing thickness and density.

Application industry:

​

• Textile/nonwoven: production of nonwoven fabrics, felt, filter materials, etc.
• Papermaking: felt cleaning, paper surface treatment.
• Printing and packaging: gravure printing, die-cutting and creasing.
• New energy: lithium battery acupuncture collagen.
