L7F-T Double Step Needle Feeding Lockstitch Sewing Machine with Cone
Detailed Description
The L7F-T adopts a robust connecting rod type needle feeding structure. This specialized feeding method makes the sewing characteristics significantly more stable, ensuring it is not easy for fabric layers to slip or shift during operation.
Additionally, the bottom step motor simultaneously controls the trimming action and the pressing foot lifting system up and down. This results in a highly reliable cutting mechanism, stable thread trims, and remarkably low-noise convenience during production. It is an exceptional choice for garments requiring clean edge trimming alongside high-quality stitch results.

Key Features
Multi-function Needle Refill Button: Realizes the function of needle filling with variable needle distance.
Clutch Type Cutter Switch: Allows easy switching between the sewing functions of cutting cloth and non-cutting cloth.
Step Motor Bidirectional Driven Technology (Patent): One step motor controls both the trimming mechanism and the pressing foot lifter, ensuring a stable trimmer operation and a quiet presser foot.
No Bearing Servo Motor: The machine connects directly with only one main shaft. This creates a more rigid build, lighter torque, and quieter motor operation.
Short Trimmer: Equipped with a double round knife trimmer system that can trim the thread down to less than 3mm, effectively reducing manual thread trimming workload.
Electronic Feed: Provides electronic material feeding to ensure the stitch remains beautiful, stable, and firmly consolidated across various fabric types.
