Synchronous Sewing Machine
The synchronous sewing machine, also known as compound feed walking foot lockstitch machine, is professional industrial equipment designed for medium and heavy materials. Different from ordinary flat sewing machines, it adopts synchronous feeding system (needle, presser foot and feed dog moving together), which effectively avoids fabric slipping, layer offset and stitching wrinkles.
This machine features stable feeding, uniform stitch density and strong piercing capacity. It can smoothly sew multi-layer fabrics, thick canvas and various leather materials without skipped stitches or thread breakage even at continuous high speed.
Built with heavy-duty cast iron body and full automatic oil lubrication system, the equipment runs steadily with low vibration, low noise and long service life. The large vertical hook fits thick threads, while adjustable presser foot stroke and high lifting clearance greatly improve operation convenience.
Optional upgraded configurations include direct-drive servo motor, automatic thread trimming, back-tacking and pneumatic presser foot lifting, which greatly improve production efficiency.
It is widely applicable for leather products, automotive interiors, sofa cushions, luggage, tents, workwear and other thick-material sewing scenarios, serving as the ideal equipment for heavy-duty sewing production.
