Abstract
1433984 Coating wires MAILLEFER SA 17 May 1974 [28 May 1973] 22252/74 Heading B5A [Also in Division G3] Coated metal wires with a constant capacitance are formed by passing the wire 7 through an extrusion head 5 and then through a watercooling vat 9, the downstream position of the vat with regard to the head being varied as a function of the capacitance measured at 10. Expansible plastics material 6 is supplied by screw 4 to the annular die slot 8 surrounding the wire 7. The hot coated wire is then passed to cooling vat 9, the position of which is varied by rotation of gear 13 by motor 14, the gear meshing with toothed rack 12 attached to the underside of the vat. The capacitance is measured downstream of the vat at 10 by a gauge 11 forming one arm of a capacitance bridge, the wire being earthed. The capacitance signal generated at 11 is compared with a predetermined value and an error signal passed to the motor 14 which alters the position of the vat. The vat may in turn generate a second signal which activates heating elements 2 or cooling means in the extrusion cylinder 3 so as to return the vat to a median position. Alternatively or in addition the error signal from gauge 11 can be passed directly to the extrusion cylinder 3 as well as to the motor 14. In a further alternative the temperature of the cylinder 3 can be adjusted manually in response to an alarm produced by the vat arriving at the end of rack 12.
