Apparatus for the production of compacts of layerwise different composition, for heavy duty electric contacts

摘要

An apparatus for producing compacts having layers of different composition. More particularly, each metal powder layer is charged in a separate work station and each is pressed in a separate work station with an individual constant pressing pressure. This is achieved by moving a number of pressing tools corresponding to the number of work stations intermittently from station to station by cyclic interchange. After each movement, charging, pressing and ejecting occur simultaneously at the respective work stations.
