Patent ES-8609698-A1 (ES)
Title: Method and apparatus for checking the wall thickness of a layer
IPC: B29C48/325
Filed: 1985-06-18
Abstract: In a method of checking the insulating sheath on a wire or cable leaving an extruder, the external diameter of the insulating sheath is continuously determined over the whole circumference by means of a first measuring apparatus and the wall thickness of the insulation is continuously detected over the whole circumference by means of a second measuring apparatus. The measured values are supplied to a computer which, inter alia, continuously determines the difference between the maximum and minimum wall thicknesses found (Wmax-Wmin). Eccentricity and minimum wall thickness of the sheath are calculated from this difference and from the measured external diameter of the insulation and the diameter of the conductor of the wire or cable, and are indicated in a display device. The measurement is thus rendered largely independent of fluctuations in sensitivity of the measuring apparatus for the wall thickness of the insulation. An apparatus for carrying out the method comprises the respective measuring apparatus and a computer for effecting the required calculations.
