Abstract

The present invention is directed to methods and apparatus for measuring the temperature of strands of material. The invention relates to a method for measuring the temperature of a strand-like material to be heated to a target temperature, comprising the steps of guiding said strand-like material in thermally conductive contact around at least one disc mounted for rotation and heated to Predefining the temperature, the difference between the temperature of the strand-like material or a value characterizing the temperature of the strand-like material is measured before and after conveyance around the disc. The invention also relates to a corresponding device.

Description

technical field [0001] The present invention relates to a method and apparatus for measuring the temperature of a strand-like material to be heated to a target temperature. The cord-like material may be a metal wire, eg a metal wire to be used as a conductor of a cable. Typically, plastic insulation is extruded onto such wires in extrusion equipment. In order to properly apply and adhere the extrudate to the wire, the wire must have a predetermined temperature. Therefore, the wire is generally heated to the target temperature in a preheating unit prior to the extrusion process. Such a preheating unit is marketed by the applicant, for example under the name PREHEATER 6000. With this unit, the wire is guided around two disks mounted for rotation, at least one of which is electrically conductive, causing a short circuit of the wire loops guided around the disks. The wire can then be heated to a target temperature using a heating device positioned between the disks. Backgrou...
