The invention relates to a stirrer-paddle filling shoe for the material feed into female die bores in a rotary press, which stirrer-paddle filling shoe is constructed modularly, in order to permit a functional change between a 2-chamber filling shoe, comprising a filling paddle wheel and a metering paddle wheel, and a 3-chamber filling shoe, comprising a filling paddle wheel, a metering paddle wheel, and a feeding paddle wheel, wherein the stirrer-paddle filling shoe comprises no gear mechanism for driving the paddle wheels. The invention further relates to a rotary press comprising the modularly constructed stirrer-paddle filling shoe, wherein the gear mechanism for driving the paddle wheels is located outside the stirrer-paddle filling shoe. The invention further relates to the use of the module stirrer-paddle filling shoe according to the invention in methods for converting the modular stirrer-paddle filling shoe from a 2-chamber filling shoe into a 3-chamber filling shoe and in the opposite direction. The function of the stirrer-paddle filling shoe can be converted outside of the tablet press as well as in the mounted state inside the tablet press.
