The invention relates to a rotary press with a rotor, whereby the rotor comprises one upper and one lower punch guide and a die plate between the upper and lower punch guides, furthermore with upper and lower press punches which interact with the die holes in the die plate, whereby the rotary press comprises several stations, namely at least one filling station in which the material to be pressed is filled into the die holes, at least one dosing station, in which the material filled into the die holes is dosed, at least one pressing station, in which the material that has been dosed and filled into the die holes is pressed through the upper and lower press punches into pellets, and at least one ejector station in which the pressed pellets are ejected, whereby at least one of the stations can be moved from its operating position to a resting position, in which the production process of the rotary press to produce pellets remains possible with the remaining stations in their respective operating positions, and the at least one station in a resting position does not affect the production process. The invention also relates to a method for operating a rotary press.

Rotary press and method for operating a rotary press

The invention relates to a pressing device for a press, in particular for a rotary press, wherein the pressing device is designed to work together with at least one press punch of the press during operation of the press so that the at least one press punch presses material located in a receiver, wherein the pressing device comprises a force measuring device for measuring the force exerted by the at least one press punch on the pressing device, wherein at least one section of the pressing device is moveable between a closed operation position and an opened maintenance position, and wherein the force measuring device in the opened maintenance position is at least partially accessible from outside. The invention also relates to a rotary press.

Pressing device for a press and a rotary press

A method for sorting tablets at a rotary press for making tablets, comprising the following steps: the individual tablets are monitored with regard to at least one property of their condition during the pressing process, and a bad-signal is generated, if a tablet does not fulfill the property, and tablets which do not generate a bad-signal being good-tablets; the good-tablets are directed from a die plate of the rotary press into a good-channel; after a bad-signal has been generated, a bad-tablet is directed into a bad-channel by means of an air blast; by means of a further air stream, which is directed into the bad-channel, the bad-tablet is accelerated into the bad-channel whereby a returning to the die plate is avoided.
