Abstract
An apparatus for filling flexible bags includes an endless conveyor having a generally horizontally oriented upper run; and a plurality of bag holders mounted on the conveyor and distributed therealong. Each bag holder includes two cooperating plates extending upwardly from the upper (working) run of the conveyor and movable towards and away from one another. The apparatus further includes a bag supplying device situated along the conveyor for introducing an empty bag between the plates of the bag holder momentarily in alignment with the bag supplying device; a filling device situated above the upper run for sequentially charging the bags with contents; a sealing device situated downstream of the filling device for sealing an open end of the bag; a discharging device situated downstream of the sealing device for releasing the bag from the holder; and a driving mechanism for moving the plates into a spread-apart position at the bag supplying device, the filling device and the discharging device and for moving the plates towards one another into a closed position at the sealing device.
