Abstract

PURPOSE: To improve the accuracy of detection of connecting points by operating a joint marker at the same instant when the connecting point passes the joint marker thereby crushing the covering of the connecting point thereafter detecting the connecting point with a spark tester.
CONSTITUTION: This is the method of detecting the connecting points of conductors from above the plastic covering extrusion-coated on the conductors, wherein a joint marker for crushing the covering during the time the covering passes the extruder and reaches a water tank is provided. The joint marker, which consists of a stationary roller 9, a knurled moving roller 10, rotary solenoid 13, etc., operates the rotary solenoid 13 at the time when the covered conductor 14 including the conductor connecting point and crushes the plastic covering by the knurling of the moving roller 10 mounted to a moving arm 11. Since the insulation at the conductor connecting point has been crushed, the connecting point is surely detected from dielectric breakdown when it passes the spark tester.
