The equipment for inserting PE liners into large volume bags is used for gluing a PE liner into a large volume bag. The operator pulls a PE liner over the spreading arms first and then spreads these arms using a switch. Then the operator applies adhesive to the liner sides and exhausts air from the liner by means of the fan after sealing the liner. A large volume bag is then slid onto the liner after exhausting and the liner is then inflated. When inflated, the PE liner sticks to the inside of the large volume bag. Then the arms are pushed together and the assembled bag is pulled down.
