     Banddicken"Messgerät   
Die vorliegende Erfindung betrifft ein Banddicken-Messgerät zur   fortlaufenden Mes-    sung, Anzeige oder Registrierung der Dicke bandförmiger Materialien.



   Zu diesem   Zweck      sindbcispielsweiseDicken-      MeGeinrichtungen    unter Verwendung von elek  tischen      Induktions-Messlehren    bekanntgeworden. Werden mit derartigen Einrichtungen Bänder gemessen, die auf höheren Temperaturen liegen, so ergibt sich der Nachteil, dass Messfehler durch die Wärmeausdehnung an dem Band anliegender Tastorgane auftreten.



   Erfindungsgemäss wird daher ein Band  dicken-Messgerät    mit an dem zu messenden Band anliegenden Tastorganen vorgeschlagen, das dadurch gekennzeichnet ist, dass die Temperatur der Tastorgane der des durchlaufenden Bandes angleichbar ist. Durch diese   Mass-    nahme werden die Anwärmfehler der Tastorgane während der Messung vermieden. Zweckmässig werden die Tastorgane mittels elektrischer Heizelemente aufgeheizt, wobei die Temperatur regelbar und ablesbar ist. Um eine Aufheizung der die Tastorgane aufnehmenden Hebelarme zu vermeiden, können dieTastorgane wärmeisolierend in diesen angeordnet sein.



   An Hand der Zeichnung sei ein Ausführungsbeispiel näher beschrieben. Die Enden der Hebel 1 und 2 tragen Tastorgane 3 und 4, zwischen denen das zu messende Band 5 hin  durchgleitet.    Im Innern der Tastorgane 3 und 4 sind elektrische Heizelemente angeordnet, an die über die Leitungen 6 bis 9 eine Spannung gelegt wird. Um Erwärmungen der Hebelarme 1 und 2 zu vermeiden und die   Heizlei-    stung niedrig zu halten, ist zwischen diesen und den Tastorganen ein wärmedämmender Isolierstoff 10 und 11 angeordnet.



   -Die Tastorgane werden vor der Messung auf die Temperatur des Bandes gebracht, so dass Messfehler ausgeschlossen sind. Der Erfindungsgegenstand ist jedoch nicht auf Tastorgane mit gleitenden Flächen beschränkt.



  Auch Banddickenmesser mit Tastrollen   kön-    nen vorteilhaft nach der Erfindung ausgebildet werden.

     Strip thickness "measuring device
The present invention relates to a strip thickness measuring device for continuous measurement, display or registration of the thickness of strip-shaped materials.



   For this purpose, for example, thickness measuring devices using electrical induction measuring gauges have become known. If tapes that are at higher temperatures are measured with devices of this type, the disadvantage arises that measurement errors occur due to the thermal expansion of tactile organs resting on the tape.



   According to the invention, therefore, a strip thickness measuring device is proposed with tactile elements resting on the strip to be measured, which is characterized in that the temperature of the tactile elements can be matched to that of the continuous strip. This measure avoids the heating errors of the tactile organs during the measurement. The sensing elements are expediently heated by means of electrical heating elements, the temperature being controllable and readable. In order to avoid heating of the lever arms receiving the feeler elements, the feeler elements can be arranged in them in a heat-insulating manner.



   An exemplary embodiment will be described in more detail with reference to the drawing. The ends of the levers 1 and 2 carry sensing elements 3 and 4, between which the tape 5 to be measured slides through. In the interior of the tactile elements 3 and 4, electrical heating elements are arranged, to which a voltage is applied via the lines 6 to 9. In order to prevent the lever arms 1 and 2 from heating up and to keep the heating output low, a heat-insulating insulating material 10 and 11 is arranged between them and the sensing elements.



   -The tactile organs are brought to the temperature of the strip before the measurement, so that measurement errors are excluded. However, the subject matter of the invention is not limited to touch organs with sliding surfaces.



  Strip thickness gauges with feeler rollers can also advantageously be designed according to the invention.
