Abstract: Disclosed is a filling unit (10) for a rotary press (12), comprising a filling wheel (14), a metering wheel (24), a feeding wheel (30) and a medium unit (36), wherein the filling unit (10) is designed in such a way that the feeding wheel (30) can be connected to and disconnected from a delivery path of the medium to be metered, in particular by having a pivoting device (33) perform a pivoting movement, in particular about an axis of rotation (42) of the metering wheel (24), which is in the form of an impeller (20, 26, 32). Also disclosed is a method for providing an optimized rotary press.

Abstract: A filling unit (10) for a rotary press (12) with a filling wheel (14), a dosing wheel (24), optionally a feed wheel (30) and a medium feed unit (36), wherein the blades (22, 28, 34) of the filling wheel (14), dosing wheel (24) and/or feed wheel (30) designed as an impeller wheel (20, 26, 32), are designed in such a way that a conveying surface (40) of the respective blades (22, 28, 34) can be varied in shape, and a method for providing an optimized rotary press is proposed.

Abstract: A drinking straw for administering an active substance has a wall with a first end and with a second end. One of the two ends of the wall can be closed releasably with a closure element. A membrane, on which the active substance lies, is present in the region of the other end of the wall.
