Let us understand the work process of the V bottom paper bag making machine. We will talk about it in 6 important steps.

Step 1: Roll Paper Feeding and Folding
Roll paper feeding is the first step where the roll is fed in the reel stand through the pneumatic reel lifters. Pneumatic brake offers the required paper tension before the paper gets folded properly to the former of the printing unit. The tension of the paper reel is controlled by the dancing roller mechanism provided on the reel stand.

Step 2: Inline Printing (Optional)
The paper from the reel stand goes to the printing unit and one or two color is printed. The printing unit is based on Flexo technology in which water-based ink is used which is environment friendly. The heating drier is provided to dry the flexographic ink completely

Step 3: Forming Bag
In this the paper tube is formed by the application of the side glue unit. On the run gusset size can be changed . In this the guide rollers are provided for smooth running of the paper tube

Step 4: Cutting
In the cutting section four high carbon and high chromium knives are used to cut the paper bag to its desired length.

Step 5: Gluing
Two roller system is provided to provide the uniform layer of the glue so that proper pasting is done.

Step 6: Pasting Bottom
Now, the paper bag is almost ready, and it has to use a system of rollers. These rollers press the bags to keep the folding ends intact and produce them wholly in a single piece.

Step 7: Delivery of the bag
Here, a big drum is provided which delivers the finished bag on the delivery table in the vertical direction. The counting of the bags is automatically done with the counting mechanism provided in the section
