Abstract
The invention relates to an apparatus for advancing an empty sack in a conveying direction to a filling station comprising a charging funnel, which comprises a magazine containing a stack of horizontally extending flattened empty sacks, from which uppermost sacks are successively removed and each uppermost sack is horizontally conveyed in succession. A conveyor is arranged to receive each horizontally conveyed sack in succession, and this conveyor comprises a horizontal support for at least partially supporting each horizontally conveyed sack in succession, a pair of suction devices adjacent a leading edge of the support and arranged at opposite sides of the sack supported thereon, the suction devices being displaceable in a direction extending transversely to the support for gripping and opening the sack on the support, and the support and suction devices being pivotal in unison between a receiving position wherein the support is positioned to receive the horizontally conveyed sack and a transfer position. A pulling-up device is arranged to recieve and grip the sack in the transfer position, and to pull the sack up to the charging funnel at the filling station.
