ABSTRACT:
A feeding screw for a slide casting machine. The feeding screw comprises a non-rotary, tubular inner part, a screw part, a vibrator arranged at the outer end of the inner part, and power transmission means for the vibrator. The mutual position of the inner part and the screw part can be changed by means of a tightening nut. Thereby the resiliency of an annular resilient means arranged in an annular space between the inner part and the screw part changes such that a desired distribution of vibration energy between an extended vibration portion of the screw and the screw itself is obtainable.
