Abstract

1,049,232. Pelletizing plastics material. BLACK-CLAWSON CO. Feb. 24, 1964 [Feb. 27, 1963], No. 7571/64. Heading B5A. A pelletizer for plastics material comprises an extrusion head 10 containing a hub 65 carrying severing knives 70 rotatable adjacent the outer face of an annular die plate 25 supported by a mandrel 32. The pellets are carried away in a flow of water through a housing 60 surrounding the die outlets. Water is supplied to the housing 60 through an inlet pipe 81 and passages 82, and part flows through passages 87 (Fig. 8, not shown) in the hub 65 and past the knives 70, whilst another part flows through the mandrel to cool and lubricate its bearings. Serpentine passages 140 (Fig. 5, not shown) are provided in the die plate 25 for the flow of a cooling or heating medium.
