ABSTRACT:
A device for filling prefabricated cirgarette tubes, especially filter-tipped cigarette tubes, comprising a tobacco pressing chamber (14) with a filling opening (13), in which tobacco introduced through the filling opening (13) is pressed to form a tobacco rod (10) by means of a pressing beam (17) movable transversely to the longitudinal direction of the tobacco pressing chamber (14), a socket for fitting the cigarette tube thereon, clamping means for retaining the cigarette tube on the socket, and an ejector (25) for ejecting the tobacco rod (10) from the pressing chamber (14) into the cigarette tube. In order to prevent tobacco fibres from projecting out of the filling opening of the tobacco pressing chamber, a separate lid (1) cooperates with the filling opening (13) of the tobacco pressing chamber (14), the closing movement of said lid being in advance of the movement of the pressing beam (17) is pressing direction. Preferably, the tobacco rod (10) is overcompressed prior to being ejected from the pressing chamber (14). Also, the cigarette tube on the socket is clamped diametrically during the filling operation.
