Abstract

A powder press has a lower die having an upper face and forming a cavity open upward at the face, a vertically shiftable lower piston downwardly closing the cavity, an upper piston vertically shiftable downward into the cavity, and filler shiftable between an inner position closely juxtaposed with the cavity and an outer position remote from the cavity for pouring a fluent powder into the cavity in the inner position and forming therein a powder mass. An actuator upwardly shifts the lower piston and thereby pushes up the powder mass such that a portion of it projects above the face. An element carried on the filler and shiftable over the surface scrapes away the portion of the mass projecting above the surface.
