Abstract

726,291. Moulding thermoplastic pellets. STANDARD OIL DEVELOPMENT CO. July 21, 1953 [Sept, 29, 1952], No. 20203/53. Class 87 (2) To make thermoplastic pellets in the form of cubes # inch square (e.g. from a copolymer of isobutylene and styrene) the plastic is fed into an extrusion machine 10 in which it is heated and extruded through nozzle 12 in the form of adjacent rods 20 and from there between cooled embossed rollers 21 which flatten the rods and cause adherence at the point of contact; the ribs may be disposed in a spiral, circular, diamond or rectangular pattern. The web 23 is further cooled in a water trough 24 and passes past air-jets 25 onto a driven endless belt 26 which feeds it into a pelletizer. 32 where it is cut to form the cubes which emerge from shoot 33 and have any electrostatic charge removed by radium-containing bar 35.
