Even minor electrical faults can disrupt pattern accuracy or halt machine operation entirely.

The cam system controls needle motion and stitch formation. Misalignment or wear can lead to uneven loops or mechanical stress. Routine checks should verify:

• Cam positioning
• Belt tension
• Gear alignment
• Motor stability

Textile manufacturers typically follow two maintenance approaches:

This strategy involves scheduled servicing to prevent failures before they occur. It includes cleaning, lubrication, inspections, and component replacement at predefined intervals. Preventive maintenance is widely regarded as the most cost-effective method because it minimizes emergency repairs and downtime.

Corrective maintenance occurs after a machine fault or breakdown. While sometimes unavoidable, relying solely on corrective maintenance can result in production losses, urgent spare-parts procurement, and higher repair expenses.

With the integration of sensors and monitoring software, predictive maintenance is becoming increasingly popular. This method uses real-time data to predict component wear and schedule maintenance precisely when needed, optimizing efficiency and reducing unnecessary servicing.

Routine daily inspections are essential for maintaining machine performance. Operators should perform the following checks before each shift:

• Remove lint and debris from machine surfaces
• Inspect needles for visible damage
• Check yarn tension consistency
• Verify lubrication levels
• Listen for abnormal noise
• Confirm pattern program accuracy

Daily care prevents small issues from escalating into serious mechanical failures.

In addition to daily routines, deeper inspections should be scheduled regularly.

Weekly Tasks

• Clean yarn feeding assemblies
• Inspect electrical connections
• Check drive belts
• Examine cams for wear

Monthly Tasks

• Test sensor calibration
• Inspect motors and bearings
• Flush lubrication lines if necessary
• Check structural bolts and fasteners

A structured maintenance calendar helps ensure that no critical component is overlooked.

Even well-maintained Jacquard knitting machines may encounter occasional issues. Recognizing early warning signs can prevent serious breakdowns.

1. Pattern Errors

Often caused by software glitches, damaged cables, or faulty sensors.

2. Yarn Breakage

Usually due to excessive tension, rough yarn guides, or improper lubrication.

3. Machine Vibration

May indicate worn bearings, loose bolts, or unbalanced drive systems.

4. Overheating

Often linked to insufficient lubrication or blocked ventilation.

5. Uneven Fabric Texture

Can result from misaligned cams or worn needles.

• Stop the machine immediately if abnormal noise occurs.
• Identify the problem area before restarting.
• Replace faulty components instead of temporary fixes.
