Patent number: 6595767Abstract: A rotary compression press for cylindrical compacts, especially tablets, comprising a rotatably driven rotor including a die-plate and an upper and a lower ram guide for upper and lower rams cooperating with the die bores, and a pressure station with an upper and a lower pressure roller for applying a pressing power to the rams wherein the rams circumferentially have an annular tooth system which cooperates with an opposed tooth system in the area of a pressure station for the rams for the purpose of rotating the rams in the die bores thereof, characterized in that the opposed tooth system is defined by a rotatably supported gear which is acted on by a preset braking torque with the braking torque being chosen so as to be smaller than the torque of the ram when under a maximum pressing power.Type: GrantFiled: July 19, 2000Date of Patent: July 22, 2003Assignee: Wilhelm Fette GmbHInventors: Jürgen Hinzpeter, Ulrich Arndt, Heinrich Behrmann, Helmut Bommrowitz, Thomas Heinrich, Thomas Jacob, Peter Lüneburg, Nils Petersen, Hans-Joachim Pierags, Wolfgang Röhrs, Elke Wittenberg, Hans Wolf, Ulrich Zeuschner

Patent number: 6361305Abstract: A rotary tablet press, with a die plate rotatably mounted in a housing, which comprises guides for the upper and lower punch, whose position is controlled by cam disks rigid with the housing, and with an upright drive shaft which is arranged below the die plate and which can be releasably coupled to the die plate, wherein the die plate is formed such that after releasing from the drive shaft and a slight raising it may be moved out laterally, wherein at the ends, facing one another, of the die plate and drive shaft there is provided a quick locking whose parts are arranged in cavities of the die plate and drive shaft and which may be actuated by an actuation rod which is movably mounted in an axial channel of the drive shaft and is actuatable by an actuation device for the selective tensioning or releasing of the die plate and drive shaft.Type: GrantFiled: April 18, 2000Date of Patent: March 26, 2002Assignee: Wilhelm Fette GmbHInventors: Jürgen Hinzpeter, Ulrich Zeuschner, Hans-Joachim Pierags, Nils Petersen, Peter Lüneburg, Elke Wittenberg, Ulrich Arndt, Hans Wolf
