Bag-top fold-over device for folding woven bags or laminated bags prior to sewing
This bag top folding device integrates a trimming unit and a crepe-paper dispenser, allowing operators to adjust the trimming height freely to match different bag specifications. When paired with Detai’s bag sewing machines, pedestals, and conveyors, it can automatically complete bag-top trimming, crepe-paper application, and stitching in a single continuous process. The bag-top fold-over device is widely used on packaging lines in the grain, chemical, and port logistics industries, where consistent bag appearance and secure sealing are essential.
