Introduction

Efficient operation of circular knitting machines is crucial for enhancing knitting quality and productivity. Understanding the proper methods of threading, opening cloth, and changing yarn is essential for optimizing machine performance. This article provides a comprehensive guide to the operational procedures for circular knitting machines, offering insights into best practices for both new and experienced operators.

Threading the Yarn

The initial step in preparing a circular knitting machine is to correctly thread the yarn. Proper threading ensures a smooth knitting process and reduces the risk of machine malfunctions.

Step-by-Step Threading Process

1. Set Up the Yarn Frame

Place the cylinder yarn on the yarn frame. Locate the yarn head and thread it through the yarn guide on the frame's ceramic eye.

2. Pass Through Tensioners

Feed the yarn through two tensioner devices. Pull the yarn downwards and guide it into the yarn feeding wheel.

3. Introduce to Feeding Ring

Thread the yarn through the center stopper, guiding it into the eye of the main machine feeding ring. Ensure the yarn head is stopped and directed into the needle.

4. Wrap Around Yarn Feeder

Wrap the yarn around the yarn feeder. This completes the threading for one yarn feeding port.

5. Repeat for Other Ports

Follow the same steps for all remaining yarn feeding ports to ensure a complete setup.

 

Opening Cloth

Once the threading is complete, the next phase is to open the cloth. This involves ensuring all components are ready for knitting.

Steps to Open Cloth

1. Preparation

Deactivate the active yarn feeding system.

Open all closed needle tongues.

Remove any loose floating yarn heads to ensure that the knitting needles are clear and ready for use.

Detach the cloth support frame from the machine.

2. Introduce Yarn into Hooks

Feed the yarn into the hooks through each feed and pull it to the cylinder's center.

3. Weave and Knot

After threading all yarns, bundle them together and ensure even tension before tying them securely. Use the winding shaft of the winder to tighten the knot on the winder stick.

4. Initial Machine Check

Operate the machine at "slow speed" to verify that all needles are open and that yarns are feeding correctly. If necessary, use a brush to assist with the yarn feeding process.

5. Open Cloth at Low Speed

Gradually open the cloth at a low speed. When the fabric reaches a sufficient length, reattach the fabric support frame and guide the cloth evenly through the winding shaft of the fabric winder.

6. Engage Active Yarn Feeding

Once the machine is ready for normal weaving, activate the yarn feeding device. Adjust the tension of each yarn evenly using the tensioners, allowing for high-speed operation during the weaving process.

Changing Yarn

Occasionally, operators will need to change the yarn due to depletion or when switching to a different material.
Understanding the correct procedure is vital for maintaining continuity in production.

Yarn Change Procedure

1. Remove Empty Yarn Cylinder

Detach the empty yarn cylinder from the machine and carefully tear off the remaining yarn.

2. Prepare New Yarn Cylinder

Take the new yarn cylinder and check its label. Verify that the batch number matches the intended specifications.

3. Load New Yarn Cylinder

Insert the new yarn cylinder into the holder designed for cylinder yarn. Pull the yarn head through the yarn guide ceramic eye on the holder, ensuring smooth and unrestricted flow of the yarn.

Conclusion

The operation of circular knitting machines relies heavily on the correct execution of threading, opening cloth, and yarn changing processes. By adhering to these guidelines, operators can enhance the efficiency and quality of their knitting operations. Continuous training and attention to detail will lead to improved productivity and greater machine longevity. Understanding these procedures not only ensures optimal performance but also empowers operators to troubleshoot potential issues effectively, thereby maintaining the high standards expected in knitting production.
