Double Needle Lockstitch Machine fix bar big shuttle
Special for Heavy duty operation.
A Double Needle Lockstitch Machine with a fix bar and a big shuttle is a specialized sewing machine designed for heavy-duty operations. This type of sewing machine is commonly used in industries where thick and heavy materials need to be stitched together, such as in upholstery, leatherwork, or canvas work. The double needle setup allows for parallel stitching, which can create a strong and durable seam.
Here are some key points to consider for using and maintaining a Double Needle Lockstitch Machine for heavy-duty applications:
Needle Size and Type: Use appropriate needle sizes and types for the materials you're working with. Heavy-duty fabrics may require thicker and stronger needles.
Thread Selection: Choose strong and durable thread suitable for the materials you're sewing. Heavy-duty polyester or nylon threads are often used for such applications.
Tension Adjustment: Proper thread tension is crucial. Make sure that the tension is adjusted correctly for both needles to ensure even and secure stitching.
Bobbin Thread: Wind the bobbins with the same type of thread as the top thread. Ensure the bobbin thread is correctly loaded and threaded.
Stitch Length: Adjust the stitch length according to the material being sewn. A shorter stitch length is often preferred for heavy fabrics to create a tighter and more secure seam.
Feed Dog and Presser Foot: Ensure that the feed dogs are set correctly to advance the material evenly. Adjust the presser foot pressure as needed for the material's thickness.
Lubrication: Keep the machine well-lubricated according to the manufacturer's recommendations to reduce friction and extend the machine's lifespan.
Regular Maintenance: Clean the machine and change needles regularly. Keep an eye on the shuttle, hook, and bobbin case for any signs of wear and replace them when necessary.
Stitching Techniques: Learn proper stitching techniques for heavy materials. It may require slower and more deliberate sewing to maintain accuracy and stitch quality.
Safety Precautions: When using a heavy-duty sewing machine, always follow safety guidelines to protect yourself from potential injuries. Be aware of the machine's moving parts and keep your hands and fingers clear.
Troubleshooting: Familiarize yourself with common issues and solutions for your specific sewing machine model. If you encounter problems, consult the user manual or seek assistance from a professional technician.
