The roll of sealing paper (or other packaging materials) The guide roller drives the introduction to the lapel shaper. After being bent, it is overlapped by the longitudinal sealer into a cylindrical shape. The material is actively measured and filled into the finished bag. The bag tube is intermittently pulled downwards, and finally a flat bag with three sides sealed on the longitudinal seam is formed to complete the sealing of one bag.
