Date Nov. 2, 1989.Feed screws are used for container filling machines in order to separate a series of approaching containers at a specific distance from each other. Feed screws for non-rotationally symmetrically shaped containers are milled with a milling tool rotating at a high rpm, the shaft of which is arranged parallel to the longitudinal axis of the feed screw that rotates at a lower rpm. To avoid feed screw flank errors, the rotating milling tool is moved up and down in an oscillating manner, so that a milling tool can be used, the contours of which agree exactly with the associated cross sectional area of the containers which are to be handled. The first shaft of the milling tool is attached to a sliding carriage, which is movably guided in an upward and downward direction by means of a crank mechanism.
