Abstract
An apparatus for granulating thermoplastics materials comprising a nozzle plate and a cutter device in which the spacing between these integers can be pre-set and accurately maintained. This is achieved by isolating the component parts of the granulation apparatus, particularly a housing for the cutter device, which is subjected to variable thermal expansion, from the components which locate the cutter device in front of the nozzle plate.
