Abstract: An apparatus for the production of pressings from bulk material in powder, piece, swarf or fiber form, in which the bulk material is fed to rotating working elements, wherein two similar disc dies (1, 2) having conical surfaces (15, 16) in the region of a ring are rotatingly mounted by means of shafts (10, 11) opposite to one another in similarly mutually opposite machine bodies (3, 4) in such manner that the axes of the shafts (10, 11) intersect at an obtuse angle, preferably greater than 150*, and the disc dies (1, 2) come into contact with one another on a common generatrix of their conical surfaces (15, 16) and roll on one another on rotation in the same direction, while a feed device (13) and a discharge device (14) are associated with the disc dies (1, 2) and the machine bodies (3, 4) are connected with one another by elements which produce a force-operated engagement.
