Abstract
Method and apparatus for automatically filling bags with particulate materials in which the method may comprise the steps of: vertically suspending a bag having a sealed bottom and an open top; filling the suspended bag through its open top with particulate materials to near a predetermined net weight; weighing the suspended bag and its contents as the filling continues; terminating the filling of the bag in response to reaching a predetermined net weight; and sealing the top of the bag. The apparatus may comprise: a suspension assembly for vertically suspending the bag; a filler tube through which particulate materials may be dispensed from a central source; weighing apparatus attached to the suspension assembly for indicating the net weight of particulate materials being dispensed into the bag; and control apparatus connected to the weighing apparatus for arresting filling through the filler tube in response to indication from the weighing apparatus that the bag has been filled to its predetermined net weight.
