product description

This machine adopts dual straight needles, vertical automatic oiling, rotary hook threading, and slide rod thread picking, forming a two-row double-thread lockstitch. The needle bar swinging and feed conveying are synchronized, ensuring uniform stitching and preventing the sewing material from slipping. The rotary knob disc adjusts the stitch length and the lever-type reverse feeding mechanism makes the operation easier. The upper and lower shafts are supported by ball bearings, and the synchronous toothed belt rotates. The plunger-type oil pump lubrication system is suitable for sewing shirts, uniforms, coats, women's underwear, jeans, etc.
