Liquid Filling 4. Rotary and straight-line Fillers The rotary filler removes the containers from the conveyor onto a rotating plate which carries them in a circle through the filling machines. The filling heads rotate with the containers as they are filled, so that there is a continuous motion(Figure 20.2 动画 Figure 20.2 Rotary filling
