1、YS-341-L Tubular Single-Needle Sewing Machine is equipped with a synchronous feeding system for the needle, feed dog, and presser foot to prevent fabric slippage and produce neat, uniform stitches. It utilizes a slide-bar thread take-up mechanism and an imported vertical double-size rotating hook to form two parallel rows of lock stitches. The upper and lower shafts are driven by synchronous toothed belts, and the stitch length is adjusted via a knob-type dial, while a lever-operated forward/reverse feeding mechanism ensures user-friendly operation. Additionally, a clutch-type safety device is installed to protect the machine from damage due to overload

2、This model can be optionally equipped with an electronic positioning motor, allowing the needle to be controlled to always stop either above or below the fabric during sewing pauses. This eliminates the need to frequently rotate the handwheel when stopping the machine, making operation more convenient

This product is widely used in sewing applications such as tents, arches, parachutes, hot air balloons, seat cushions, and sofas. It is particularly suitable for filter bags and ring‑shaped cylindrical items
