Maintenance and Care of Automatic Circular Knitting Machines


Automatic circular knitting machines are widely used in the textile industry for producing various knitted fabrics. These machines play a crucial role in the manufacturing process, and their proper maintenance and care are essential to ensure their optimal performance and longevity. This article aims to provide an overview of the maintenance and care practices for automatic circular knitting machines.

1. Regular Cleaning

Regular cleaning is a fundamental maintenance practice for automatic circular knitting machines. Dust, lint, and other particles can accumulate on the machine's components, leading to increased friction and wear. Cleaning should be done using soft brushes, compressed air, and lint-free cloths to remove these contaminants from areas such as the needle bed, cylinder, and sinker ring. It is important to follow the manufacturer's guidelines to avoid damaging sensitive parts.

2. Lubrication

Lubrication is critical for ensuring smooth operation and reducing friction between moving parts. Automatic circular knitting machines have various lubrication points that should be regularly checked and lubricated according to the manufacturer's recommendations. Different types of lubricants, such as oil or grease, may be required for different components. It is important to use the correct type and amount of lubricant to prevent damage and maintain optimal machine performance.

3. Inspection of Needles and Sinkers

The needles and sinkers of the circular knitting machine are subject to wear and tear during operation. Regular inspection of these components is necessary to identify any damaged or worn-out parts. Broken or bent needles should be replaced immediately to prevent damage to the fabric or other components. Similarly, damaged or worn-out sinkers should be replaced to ensure proper fabric formation.

4. Tension Adjustment

Proper tension adjustment is crucial for achieving the desired fabric quality and avoiding knitting defects. Automatic circular knitting machines have tension devices that need to be checked regularly and adjusted as required. Uneven tension can result in stitch irregularities, loops, or even broken yarns. Regular monitoring and adjustment of tension ensure consistent fabric quality and minimize production issues.

5. Calibration and Alignment

Calibration and alignment of automatic circular knitting machines are important for maintaining their accuracy and precision. The machine's components, such as the needle cylinder, sinker ring, and cam system, should be periodically checked for proper alignment and calibrated if necessary. Misalignment can cause uneven fabric tension, distorted patterns, or even machine jams. Regular calibration and alignment help ensure optimal machine performance.

6. Electrical System Maintenance

The electrical system of an automatic circular knitting machine needs regular inspection and maintenance to prevent malfunctions and ensure safety. Loose connections, damaged cables, or faulty sensors can lead to operational issues or even pose a risk to the operators. Regular inspection of the electrical system, including wiring, switches, and sensors, is essential to identify and address any potential issues promptly.

7. Software Updates

Many automatic circular knitting machines come with software-controlled functions and features. Regular software updates provided by the manufacturer help improve machine performance, add new functionalities, and address potential bugs or security vulnerabilities. Keeping the machine's software up to date ensures optimal operation and access to the latest advancements in knitting technology.

8. Operator Training and Safety

Proper operator training is crucial for the safe and efficient operation of automatic circular knitting machines. Operators should be trained on machine operation, maintenance procedures, and safety protocols. They should be aware of potential hazards, such as moving parts, hot surfaces, and electrical risks, and follow proper safety precautions. Well-trained operators can detect and address minor issues promptly, minimizing downtime and potential damage to the machine.


Maintenance and care are vital for the optimal performance and longevity of automatic circular knitting machines. Regular cleaning, lubrication, inspection of components, tension adjustment, calibration, electrical system maintenance, software updates, and operator training all contribute to a well-maintained machine. By following these practices, textile manufacturers can maximize productivity, achieve consistent fabric quality, and extend the lifespan of their automatic circular knitting machines.
