Abstract
Abstract A high-productivity packaging apparatus and method utilize a container and a plurality of circular arranged metering units or ''''traps'''' which communicate and rotate with the container. The individual traps have fixed internal guide surfaces but no moving parts. During rotation around the container axis each trap successively draws from the container in excess of a unit of material to be packaged, then traps a unit and discharges the excess and during continued rotation the material is directed along the guide surfaces towards a trap outlet to be discharged at a discharge station to which empty containers are fed successively in synchronism with successive traps being discharged.
