  • Method and arrangement in a drive device of a rod coating station
    Patent number: 6786972
    Abstract: A method and arrangement using the drive device of a rod coating station to carry axial forces, in which the drive device includes at least a telescopic articulated shaft, at the first end of which is a changeable grooved rod and at the opposite end of which is the shaft of the drive motor. The rotation of the rod creates an axial force, which is cancelled by a counterforce from the articulated shaft side, which is brought to the end of the rod. The counterforce is brought to the rod through the articulated shaft from the drive motor side.
