Abstract

The plasticising screw 12 e.g. of an injection moulding machine, has a helical thread whose profile is broad and flat-topped over most of the screw, but narrower and sharper, i.e. triangular, in the inlet zone Ia to aid cutting-in of the strip of material and reduce friction thereby. Friction in the zone Ia may be reduced further, by the height of the crest fluctuating along its length, and the thread being cut deeper. <IMAGE>
