Double Needle Lockstitch Sewing Machine For Heavy-Duty

DESCRIPTION

The machine features a double straight-needle design with a vertical automatic refueling hook for thread picking, utilizing a slide bar mechanism to form a double-line lockstitch pattern. Its synchronized needle bar swing and fabric feeding system ensure even stitching while preventing material slippage. The rotary dial allows for easy stitch length adjustment, and the bar-driven feeding mechanism simplifies operation. Supported by ball bearings, the upper and lower shafts rotate via a synchronous toothed belt, while a plug pump lubrication system ensures smooth performance and longevity.
