Automatic bag sewing heads with a two-needle, four-thread chain stitch create two parallel stitch lines, giving the bag a tighter and more secure seal. This version is developed from the GK35-6A sewing head, but adds a reinforced stitching pattern that helps reduce material leakage and keeps the seam more even during long production runs. The stable stitch spacing also makes daily operation smoother, which is useful for packaging lines that need reliable closure for paper sacks, woven plastic bags and jute bags.
