Claim:
Powder press for the production of a metal powder compact with an upper punch arrangement, a lower punch arrangement and a die arrangement which forms the mold cavity into which the metal powder can be filled; and then, to form the compact the upper punch arrangement and the lower punch arrangement can be pressed together in the pressing direction, controlled by a control unit; and the lower punch arrangement is equipped with a plate on which the die arrangement is fastened and to which plate cross pressing devices are fastened, each being equipped with a cross pressing punch which can be linearly driven by a drive unit and which can be pressed into and refracted out of the mold cavity in the cross pressing direction through an opening in the die which is essentially perpendicular to the pressing direction, wherein the drive unit of each cross pressing device comprises a linear drive unit with a fixed part fastened to the frame of the cross pressing device and a part which can be moved linearly relative to the fixed part, said linearly moveable part being connected to a first wedge whose wedge surface acts on the wedge surface of a second wedge which can essentially be moved perpendicularly to the first wedge in the direction of the cross pressing.
