Roll Fed Square Bottom Paper Bag Machine

The SBH series SOS bag making machine is designed to manufacture square bottom paper bags from paper roll in blank or printed designs. Side gluing, tube forming, cutting, bottom creasing, bottom gluing, bottom forming and final product out feed can all be completed within one cycle of the machine, making it ideal for paper bag production to be used in food storage, shopping bags and other common paper bag uses. The machine use German machinery manufacturing technology and ideas, including a high speed movement the central control system (CPU) control, touch screen display, and servo motor control system bag length to produce bags in various specifications. The SBH290 Basic can have a servo patch unit or servo open window unit attached in order to add a transparent window to the paper bag, thus offering more value to a client.

  • USA VALCO Cold Glue Adhesive System
  • Bag Production Part
  • Mechanical Drive

1. The roll fed square bottom paper bag machine is equipped with a Japanese Mitsubishi servo system and SICK photocell for correction, so that users can accurate track printed material, and minimize adjustment and pre-set times.
2. It is equipped with a Mitsubishi electric control system and Mitsubishi motion controller (CPU). This achieves an integration of an optical fiber in order to achieve a high speed and high precision, motion control and production flow test. With a touch screen display, the operation functions are clear, and feature a great human to machine interface.  
3. Equipped with a tension system and automatic WEB correction system, this paper bag production machine can reduce waste and improve efficiency.
4. Side sealing, and adjustment of the glue volume with an automatic mechanical speed saves glue.
5. The automatic fault alarm, equipped with paper web detector, avoids damage to the machine caused by paper jams.
