ABSTRACT:
An apparatus to cool and granulate strands discharged in a molten state from nozzles, particularly strands formed of plastics materials, includes a feeder trough having at its receiving end a collecting region disposed below the nozzles and a granulator at the opposite end thereof. The feeder trough includes over its entire length, a collecting region and a transport region, a longitudinally grooved perforated plate or screen material in which only a single strand is conducted along each groove, the strands being borne and guided along the grooves of the feeder trough by a gas current that passes through the plate material, aided by longitudinally directed gas current that may be blown along the grooves from a source disposed at the receiving end of the trough ahead of the collecting region.
