Essential Guide to Circular Knitting Machine Parts: Types, Functions & Maintenance

Circular knitting machines are the workhorses of the textile industry, producing seamless tubes of fabric for everything from t-shirts to socks. Their efficiency and output depend heavily on the precise function and condition of their numerous components. This guide delves into the essential circular knitting machine parts, explaining their roles and how to care for them.

Core Components and Their Functions

Understanding the main assemblies is key to grasping how these machines operate. Each part plays a critical role in the loop-forming process.

The Needle Bed and Cylinder

This is the heart of the machine. The cylinder is a precision-machined metal barrel with slots that house the knitting needles. Its diameter determines the fabric tube’s width. The needles, driven by cams, move in and out to form loops of yarn.

Feeding and Yarn Guidance Systems

This system ensures yarn is delivered to the needles smoothly and at consistent tension. It includes yarn feeders, tensioners, guides, and stop motions that halt the machine if a yarn breaks, preventing defects.

Take-Down and Fabric Rolling Mechanism

Once knitted, the fabric is gently pulled away from the needle area by rollers. This take-down process controls the fabric density (tightness of the knit) and winds the finished product onto a cloth roller for easy handling.

Routine Maintenance for Longevity

Regular maintenance is non-negotiable for optimal performance and fabric quality. A proactive schedule prevents costly downtime.

Daily & Weekly Checks: Clean lint and fiber dust from the needle bed, feeders, and sensors. Visually inspect needles for hooks or damage. Lubricate moving parts as per the manufacturer’s manual, using only recommended oils.

Periodic Overhauls: Schedule professional servicing to check cam settings, alignment, and wear on critical parts like sinkers and circular knitting machine parts. Replacing worn components before they fail is the most effective maintenance strategy.

Frequently Asked Questions (FAQ)

Q: What is the most commonly replaced part on a circular knitting machine?

A: Knitting needles are the most frequently replaced due to wear and tear. Keeping a stock of high-quality needles is essential for continuous operation.

Q: How does cam design affect the fabric?

A> The cam track’s shape dictates the needle movement. Different cam designs create various knit structures, like plain jersey, rib, or interlock patterns, offering production versatility.

Q: Why is consistent yarn tension so important?

A> Fluctuating tension leads to defects like slubs, dropped stitches, or uneven fabric weight. Properly maintained tensioners and guides are crucial for uniform quality.
