The Sewing Head Assembly is the core stitching mechanism of an industrial upholstery sewing machine. It drives the needle and forms stitches by converting rotary motion from the main shaft into precise needle and hook movements, enabling the machine to sew thick materials securely.
Needle size is specified in Nm (metric) and should be chosen based on thread and fabric thickness. The reference range is Nm 90–200, but you must verify the appropriate size with the machine manufacturer or needle supplier for your specific material and thread combination.
Key parameters include stitch length, max sewing speed, max stitch width, presser foot lift, needle bar stroke, thread tension range, lubrication oil capacity, weight, operating temperature, and noise level. All values are reference ranges; confirm them with the manufacturer for your intended use.
Unusual noise, skipped stitches, inconsistent thread tension, or visible wear on components are signs of potential issues. Regular lubrication and inspection are necessary. If problems persist, consult the manufacturer or a qualified technician to avoid exceeding operational limits.
