a granulator primarily intended for in situ use in combination with an injection molding machine such that plastic scrap such as sprues and runners generated in such formation of plastic parts may be granulated thereby . the granulator is adapted for disposition within the confines of the injection molding machine and particularly within the drop out area thereof . a pair of rails guide the granulator in such drop out area and enable it to be laterally withdrawn to one side of the molding machine for repair , parts changes , cleaning and the like . the specific construction of the granulator includes a pair of meshed paddle rolls serving as a combination metering and feed device and removal means to remove granulated material to that end of the granulator disposed proximal said one side of the machine so as to enable efficient and quiet in situ granulation of plastic scrap generated from the injection molding procedure in a manner heitherto unattainable .
