GS-9CU Bag Sealing Sewing Machine

The GS-9CU Bag Sealing Sewing Machine is a double-thread chain industrial sewing machine developed from the GS-9C. Its primary design feature is simultaneous upper and lower teeth feeding, combined with a relatively large 7–11.5 mm stitching range, making it suitable for stitching thick and slippery materials. The GS-9CU operates with a maximum sewing speed of 2700 r/min and a working speed of 2500 r/min. It uses double-thread chain stitching type 401, a DR-H30#26 needle, a paper-bag cutting arrangement and a built-sump lubrication system. The machine weighs approximately 42 kg and has an outline dimension of 410 × 250 × 400 mm. Its upper-and-lower feeding arrangement makes the GS-9CU particularly relevant for applications where thicker or slippery materials need controlled feeding during the sewing process.
