The device (1B) has an expelling device which is provided for simultaneously expelling the material components from the cartridges (2.1,3.1) into cartridge receiving device with ejection piston (11). A mixing device (17) is provided for mixing and discharging the expelled material components with a transmission unit (8). The transmission unit has a detector (12) which detects the reaction pressure that builds up during expulsion of fabric components. A control unit (14) is connected to input side of detector for realization of drive control function in response to detection result.
