Abstract
A bag filling process and machine wherein material to be bagged is force fed into a tunnel from an end and wherein the material is compacted and fed through the tunnel and out the opposite end which opens into a bag surrounding the tunnel. To avoid compacting and filling of the bag from the bottom up, a ramp in the bottom of the tunnel directs the flow of material to a mid-height position to promote compacting and filling of the bag from the mid-point position both downwardly and upwardly from the ramp end.
