GKN-2WLU Double-Thread Chain Industrial Sewing Machine

The GKN-2WLU Double-Thread Chain Industrial Sewing Machine uses a plane-feeding configuration with reverse two-needle, four-wire stitching and synchronized feeding from both the upper and lower sides. The catalogue states that it can work with the forward head of the machine to complete stitching of both upper and bottom seams. The GKN-2WLU uses an upper-tooth feeding mechanism together with lower teeth feeding the material at the same time. The catalogue specifies the machine for thick and smooth materials and bag-production applications. The two seams use the same line spacing and stitch length, which is described as helping prevent material leakage. The machine provides a 7–11 mm stitching range and a maximum sewing speed of 2800 r/min. It uses double-thread chain stitching type 401, UY143GS-200 or 230 needles, 20/6 or 20/9 synthetic or cotton thread and automatic lubrication. The machine weighs approximately 35 kg and measures 430 × 220 × 400 mm.
