Abstract
A granulator primarily intended for the granulation of plastic scrap material in which a pair of meshed paddle rolls serve as a combination metering and feed device through which such plastic material is fed to the granulator. The paddle rolls are mounted in such a manner and driven by drive means which enable one of the paddle rolls to move laterally away from the other paddle roll including an angular or skewed relationship yet while still maintaining an articulated; that is, synchronized, movement of the paddle rolls in relationship to each other.
