Abstract

1,182,979. Extruder heating systems. OTDEL MAKHANIKI POLIMEROV. 14 June, 1968, No. 28291/68. Heading B5A. [Also in Division H5] An electrical heating system for an extrusion moulding machine comprises an electrically conductive element connected in series with the extruder barrel and arranged coaxially therewith and in spaced relationship thereto over a major portion of the length of the element. As shown, a casing 6 is in electrical contact with barrel 1 at its downstream end. A circuit is formed by connection of transformer 5 at 8, 9 with components 1, 6 in series, the heating being essentially due to induction. Barrel 1 heats up more quickly and reaches a higher temperature than casing 6 and the heating effect may be varied by rotating casing 6 which thereby moves longitudinally due to the screw threading at 7. In a second embodiment, Fig. 2 (not shown), the barrel 1 is in series with screw 2, contact being made via die 4.
