Machine Configurations

2. FEEDING UNIT
  The roll paper fixed on the air expanding mandrel can be fed by swing arm which is equipped with lifting hydraulic system. With an alarm function, the feeding unit will sound alarm when there is no paper feeding. Improved surface smoothness of the paper during the feeding is achieved due to the web guide and uniform tension control. Paper rolls can be easily changed by pressing a button.
2. BAG FORMING UNIT
  Form the paper with punched holes into the tube; and snap it into separate pieces based on the settings. Afterwards, these separate tubes will be sent to the drum to fold the bottom before bags collection.
2. BAG COLLECTING UNIT
  Compress the bags and outlet the bags. The number of paper bags can be processed and displayed by the automatic collection and counting system.
2. Optional inline print press can be added to achieve printing function.
