Abstract: The pasty components of a multicomponent material are first contained in separate tubular portions (11,12) which, prior to the mixing operation, are assembled together to form a cartridge (10) having a cylindrical inner wall and in which a mixing means is accomodated which consists of a rotationgly driven disk (21) and of a relatively stationary disk (18). Via a rod (29) projecting out of the cartridge (10), disk (21) is drivable by a rotating tool. By reciprocation of the rotating tool, both disks (18 and 21) are moved axially to the cartridge (10). Upon the mixing performed by displacing and redistributing of the materials, the piston (13) is advanced in order to squeeze the mixture out of the cartridge.
