ABSTRACT:
The apparatus comprises two horizontally extending blades (22, 24) mounted for turning movement about a common vertical axis (26). The blades each have a hole (28; 30) therein so arranged that, when the blades are in a first condition, the holes are aligned and a vertical column of plastic material (12) can pass through the holes. Upon the blades being turned about the common vertical axis through a predetermined angle, one clockwise and the other anti-clockwise, edges of the holes (28; 30) pass each other until the holes do not overlap and the column of plastic material passing through the holes is sheared through by edges of the holes.
