Patent ID: 7360483

Claim:
A device for a guidance of lower rams, across lower ram heads in a rotor-type rotary press in an area of a filling device wherein a charging cam is disposed between an ejector cam which precedes as viewed in a direction of production and a proportioning cam adjustable in height and is configured to lower the heads of the lower rams revolving along with a rotor from a level at an end of the ejector cam to a lower-located transition level of the proportioning cam, characterized in that a press-mounted, first charging-cam element ( 42 ) having a first filling-cam portion ( 46 ) joining the ejector cam is provided on which the lower-ram heads ( 22 ) are guided solely on a side facing a rotor axis subsequent to the ejector cam ( 38 ), an displaceable second charging-cam element ( 48 ) is provided and has a second filling-cam portion ( 52 ) on which the lower-ram heads ( 22 ) are guided solely on a side facing away from the rotor axis before encountering the proportioning cam ( 26 ), that the second charging-cam element ( 48 ) is variable both vertically and in a circumferential direction of the rotor ( 10 ) for a purpose of varying a filling depth (t) along a predetermined adjustable upward slope, and the first and second charging-cam elements ( 42 , 48 ) have third, helically shaped filling-cam portions ( 54 ) which are located between the first and second filling-cam portions ( 46 , 52 ) and are located partially opposite each other, and guide the lower-ram heads ( 22 ) jointly through a certain length, wherein an upward slope of the third filling-cam portions ( 54 ) matches with the adjustable upward slope.
