What is a Lockstitch Sewing Machine?
Lockstitch Sewing Machine: A lockstitch sewing machine makes stitches by interlacing two threads: the top thread is held in the needle; the bottom thread is held in the bobbin inside the fabric and forms the bottom stitch. It is used most commonly in apparel manufacture, and provides a good finish to both sides of the fabric.
It is often mistaken for an overlock machine (serger). Let’s look at the difference at a quick glance:
- The lockstitch machine is used to create the primary seams (rows) of the garment. Lockstitch machine is used to stitch the main seams or rows for the garment.
- Overlock machine → Used to trim edge and prevent fabric fraying.
- The majority of the garment units operate both types in the same production line.
The basic workhorse of every garment production floor is the lockstitch sewing machine for garments that is used to sew shirts, trousers, jackets, uniforms and ethnic clothing.
Why Lockstitch Machines are Essential for Garment Manufacturing
The three non-negotiables in garments making are speed, consistency and durability. Industrial Lockstitch Machines are capable of meeting all three for the following reasons:
- High-speed stitching
Modern machines operate at 5,000 – 5,500 SPM and ensure that your line is kept at full production.
- Consistent stitch quality
Digital tension control ensures even stitches over thousands of metres of fabric.
- Strong, durable seams
Interlocked thread construction is resistant to washing, stretching and wear.
- Designed to be mass produced
The machine reliably keeps up even with the production of 500 or 50,000 pieces a day.
- Low maintenance
The advantages include wear and down time reduction and elimination of repair costs with auto-lubrication and direct drive systems.
- Fabric versatility
Lightweight chiffon to heavy denim — it works for all your needs.
