Automatic Bag Making Machine for Twisted Handles Paper Bag and Flat Handles Paper Bag

This automatic paper bag making machine is designed for automatic production of paper bag with twisted handles and paper bag with flat handles. One machine can manufacture two different paper bag types, making it an ideal choice for bag making operations looking to minimize operating costs without sacrificing quality.

The production process between twisted rope handles and flat handles can be freely switched to produce the bag you need. The handles will be delivered to the main machine after being produced by the handles making unit, and being cut and pasted to the paper. This bag making machine can form the paper bag in one process from the paper roll, handle patching, side gluing, tube forming & cutting, bottom creasing & gluing and forming to bags collection in the control of Mitsubishi servo motor to ensure high precision and stability, simple maintenance and high efficiency.

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.

Handle Making unit

  • Twisted paper ropes /flat paper ropes and roll paper can be pasted together to create a handle.

Handle pasting unit

  • The handle pasting machine can automatically paste the twisted handle into the required position of bag body with the use of glue and then presses it firmly on the bag body before pre-creasing.

Bag Forming unit

  • Form the paper with patches and side glue into the tube; and cut into separate pieces based on the settings. Afterwards, these separate tubes will be sent to the drum to open the four corners, then bottom gluing, sealing and form the square shape consequently.

Bag collecting unit

  • Compress the bags and output the bags. The number of paper bags processed can be displayed by the automatic collection and counting system.
