Bag-top fold-over device for folding woven bags or laminated bags prior to sewing
This belt-type folding device prepares the bag mouth before sewing by folding the upper edge into a clean, uniform shape. Once the fold is formed, downstream sewing systems can create a stronger and more secure closure. This greatly reduces issues such as bag leakage, loose stitching, or breakage during handling and transport. It is a reliable front-end component widely used on packaging lines in grain processing, chemicals, fertilizers, animal feed, and other industries where consistent sealing quality is essential.
