1. Paper Feeding

You place a rectangular sheet of kraft or laminated paper on the feed table.

The rollers catch it and pull it inside.

2. Side Folding

The folding guides bend the left and right edges inward.

This forms the "tube" shape of the bag.

3. Bottom Folding

As the paper tube moves ahead, the machine creases and folds the bottom flap.

Glue is applied again, and pressure seals the bottom.

Now the bag is closed at the bottom and open at the top.

4. Delivery

The finished paper bag comes out to the collection tray.

Operator picks it up and stacks it.
