Abstract
An apparatus for filling sacks is disclosed which has opposed clamps for engaging the initially collapsed sacks adjacent to the side portions of their opening-defining edges, suction devices included in the clamps, which engage mutually opposite side walls of the sacks adjacent to their opening-defining edges and pull said side walls apart, and a filling pipe. The carriers for the suction devices are provided each on each side of the sack at least below the suction device or suction devices with a transversely extending bar, which is made of elastomeric material and urges the pulled apart edge portions of the sacks into sealing contact with the side walls of the filling funnel.
