ABSTRACT:
A device for the guidance of lower rams across the lower-ram head in a rotor-type rotary press in the area of a filling device wherein a charging cam is disposed between an ejector cam which precedes as viewed in the direction of production and a proportioning cam adjustable in height and is configured such as to lower the heads of the lower rams revolving along with the rotor from the level at the end of the ejector cam to a lower-located transition level of the proportioning cam, a press-mounted, first charging-cam element having a first filling-cam portion joining the ejector cam is provided on which the lower-ram heads are guided solely on the side facing the rotor axis subsequent to the ejector cam, an adjustable second charging-cam element is provided and has a second filling-cam portion on which the lower-ram heads are guided solely on the side facing away from the rotor axis before encountering the proportioning cam, that the second charging-cam element is displaceable both vertically and in the circumferential direction of the rotor for the purpose of varying the filling depth along a predetermined adjustable upward slope, and the first and second charging-cam elements have third, helically shaped filling-cam portions which are located between the first and the second charging cam portion and are located partially opposite each other, and guide the lower-ram heads jointly through a certain length, wherein the upward slope of the third filling-cam portions matches with the adjustable upward slope.
