GKN-2
Bag closing head for stitching open-mouth bags with speed up to 2700RPM
GKN-2HS/GKN-2LHS (L: Left Handed Sewing)
Bag Bottom Sewing Machine, 1-Needle 2-ThreadThe GKN-2HS and GKN-2LHS are single-needle, two-thread bottom-sewing units designed for closing the bottoms of paper sacks, PP/PE woven packaging, laminated paper bags and other lightweight materials. They use a flat-feed mechanism, and the two versions, right-handed and left-handed, give production lines more flexibility when arranging the sewing station. Their built-in lubrication system keeps the main components oiled during long hours of work, which helps them last longer and reduces how often maintenance is needed.

GKN-2U/GKN-2LU (L: Left Handed Sewing)
Bag Bottom Sewing Machine (Top and Bottom Feed), 1-Needle 2-ThreadBased on the GKN-2HS/GKN-2LHS design, these bag bottom sewing machines are upgraded with a top-feed mechanism that works together with the lower feed. The combined feeding action gives much better control when sewing thicker or more slippery materials, helping them move steadily through the machine and improving stitch quality.

GKN-2W/GKN-2LW (L: Left Handed Sewing)

The two stitch lines create a stronger hold at the bottom of the bag, making it less likely for the contents to escape while the bag is being handled.

GKN-2WU/GKN-2LWU (L: Left Handed Sewing)
Bag Bottom Sewing Machine (Top and Bottom Feed), 2-Needle 4-ThreadThese bag bottom sewing machines use a two-needle, four-thread setup that creates two stitch lines at once, giving the bag a stronger and more secure closure. They also use a top-and-bottom feed setup that gives better control over thicker or slippery materials, helping them move at a steady pace and making it easier to keep the stitching neat.
