apparatus to fill any lined semibulk bag - like container , and through mechanical functions , to remove any twists or creases which could hamper the loading or unloading process . during filling , the apparatus will automatically separate the liner from the bag , except for the bottom section which is tied . the liner is then inflated to remove any twists after which product flow is activated at a trickle rate . after an automatically sensor - controlled amount of product has flowed into the inner liner at the trickle rate , the liner is lowered to full load position and the product flow is automatically activated to full flow at a greater rate . when a second set point is reached , the trickle rate is automatically activated again to top off the container to the predetermined amount of product , after which the unit turns off for container removal .
