A transfer type of product filling machine includes a stationary deadplate positioned under a moving line of openbottom transfer receptacles. Containers moving in a separate line under the deadplate in synchronism with the line of transfer receptacles are progressively filled as the transfer receptacles pass over either a continuously tapered or a stepped termination of the deadplate to prevent bridging of loose materials or individual items across the container openings by abrupt dumping of the materials into the containers. The stepped type of deadplate termination also facilitates exact count filling of a single container from a plurality of intermediate receptacles, each holding an integral fraction of the total count fill, and speeds the filling operation by providing a plurality of filling locations.

In a machine for transferring material from an intermediate filling region to a line of moving containers in a final filling region spaced from the intermediate filling region of the type that includes a plurality of transfer receptacles each having at least one open pocket for receiving the materials to be transferred, means for delivering a predetermined amount of the materials to each of the pockets of the transfer receptacles at the intermediate filling region, means for conveying the transfer receptacles in a closed path from the intermediate filling region over the line of moving containers in the final filling region and return, means for synchronizing the movement of the transfer receptacles with the moving containers through the final filling region, and means for discharging the materials by gravity from the openings of the pockets in the transfer receptacles into the containers in the final filling region, the improvement wherein the means for discharging the materials from the transfer receptacles comprises: a stationary deadplate positioned for slidable contact with the opening of each pocket of each transfer receptacle, the deadplate extending laterally underneath the receptacles from one side to the other of the path traversed by the open pockets of the receptacles at the entrance to the final filling region for preventing the contents of the pockets from dropping through the openings in response to gravity until the opening in each pocket is no longer covered by the deadplate, and the deadplate extending longitudinally along the path of the transfer receptacles from the entrance of the final filling region for a least the length of one of the receptacle pockets, with the width spanned by the deadplate in the path traversed by the open pockets decreasing to the end of the final filling region as a function of distance from the entrance thereof for progressively uncovering the openings of the pockets to allow the materials to drop into the containers progressively as the transfer receptacles are conveyed through the final filling region.
