Description

       

  
 



  Messband aus Kunststoff
Die Erfindung betrifft ein Messband aus Kunststoff mit einer Lage in Bandlängsrichtung nebeneinander durchlaufender im wesentlichen undehnbarer Fäden. Ein derartiges Messband ist bereits bekannt.



  Es besitzt gegenüber denjenigen Bändern, die eine Einlage aus einem Glasfasergewebe haben, den Vorteil einer ausserordentlich geringen Dehnbarkeit, da die in Bandlängsrichtung sich erstreckenden Fäden nicht wie beim Gewebe durch Schussfäden gewellt sind, sondern sich vollkommen gradlinig im Band erstrecken. Bei Dehnung des Bandes können daher die Fäden nicht mehr geradegezogen werden, wie dies bei den Kettfäden des Glasfasergewebes der Fall ist. Aus diesen Gründen eignen sich Bänder mit einer Einlage aus unverwebten nebeneinanderliegenden Fäden vor allem für Messbänder.



   Bei den bekannten Messbändern mit unverwebten nebeneinanderliegenden Fäden sind diese von einem Kunststoffmantel allseitig überzogen, der im   Spritz- oder    Tauchverfahren hergestellt werden kann.



  Diese Messbänder sind jedoch kompliziert in der Herstellung, da es schwierig ist, die durchlaufenden Fäden im Spritz- oder Tauchverfahren in zufriedenstellender Weise mit Kunststoff zu umhüllen.



   Die der Erfindung zugrunde liegende Aufgabe bestand daher darin, die bekannten Messbänder aus Kunststoff mit einer Lage in Bandlängsrichtung nebeneinander verlaufenden Fäden so auszubilden, dass sie bei möglichst geringer Dicke eine möglichst grosse Festigkeit haben, dass sie auf relativ einfache und billige Weise hergestellt werden und dabei ihre beiden Bandseiten ohne zusätzliche Bearbeitung je nach Wahl glatte oder nahezu glatte Oberflächen erhalten können und dass es ferner bei ihrer Herstellung ohne zusätzlichen Arbeitsgang im Bedarfsfalle möglich ist, den beiden Bandseiten verschiedene Farben zu geben und somit Verwechslungen zu vermeiden.

   Dies wird erfindungsgemäss dadurch erreicht, dass die Lage dieser Fäden auf beiden Seiten durch je eine bandförmige Folie aus thermoplastischem Kunststoff abgedeckt ist und die beiden Folienbänder unter Einbettung der Fäden miteinander verschweisst sind.



   Die Fäden gehen bei dieser unter gleichzeitigem Aufeinanderpressen der Folien erfolgenden Verschweissung der Kunststoff-Folien eine feste Verbindung mit diesen Folien ein, so dass die Zug- und Reissfestigkeit des erhaltenen Bandes ausserordentlich gross, zumindest grösser als bei den im   Spritz- oder    Tauchverfahren mit Kunststoff umhüllten Glasfaserbändern ist, bei welchen die Gefahr besteht, dass ihre eingebetteten Fäden keine ausreichend gleitfeste Verbindung mit der Kunststoffhülle eingehen.

   Ein besonderer Vorteil des erfindungsgemässen Bandes besteht aber noch darin, dass es wesentlich einfacher und billiger herstellbar ist als diejenigen, deren Einlage im Spritz- oder Tauchverfahren umhüllt ist und dass es zur Erzielung verschiedenfarbiger Bandseiten lediglich notwendig ist, entsprechend verschiedenfarbige bandförmige Folien bei der Bandeinstellung zu verwenden.



   Die in Kunststoff eingebetteten Fäden können aus Glasfasern, aber auch Metall, z. B. Bronze oder aus Textilmaterial, beispielsweise aus Leinen, Baumwolle oder Kunstseide, bestehen. Die die Fadeneinlage abdeckenden Kunststoff-Folien können auch von einem entsprechend breiten einzigen Band gebildet sein, das in seiner Mittellinie abgeknickt ist und dessen beiderseits dieser Knicklinie befindliche Längshälften aufeinandergeschweisst sind.



   Weitere Vorteile des erfindungsgemässen Bandes ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispiels, welches in der Zeichnung in der Form eines Abschnitts teilweise aufgerissen in Schrägansicht dargestellt ist.  



   Dieses Ausführungsbeispiel des erfindungsgemä ssen Messbandes besteht aus zwei aufeinanderliegenden bandförmigen Folien 1 und 2 aus thermoplastischem Kunststoff, zwischen welche eine Lage von sechs dicht bzw. in geringem gegenseitigem Abstand nebeneinanderliegenden, im wesentlichen undehnbaren Fäden 3 angeordnet ist. Die Breite der Folienbänder übertifft die Breite der Lage der Fäden. Durch gegenseitiges Verschweissen der beiden Folienbänder 1 und 2 sind diese fest miteinander und mit den Fäden 3 verbunden.   



  
 



  Plastic measuring tape
The invention relates to a measuring tape made of plastic with a layer of essentially inextensible threads running alongside one another in the longitudinal direction of the tape. Such a measuring tape is already known.



  Compared to those tapes that have an insert made of a glass fiber fabric, it has the advantage of extremely low extensibility, since the threads extending in the longitudinal direction of the tape are not corrugated by weft threads, as is the case with fabric, but extend completely straight in the tape. When the tape is stretched, the threads can no longer be straightened, as is the case with the warp threads of the glass fiber fabric. For these reasons, tapes with an inlay of non-woven threads lying next to one another are particularly suitable for measuring tapes.



   In the case of the known measuring tapes with non-woven threads lying next to one another, these are covered on all sides by a plastic jacket which can be produced by spraying or dipping.



  However, these measuring tapes are complicated to manufacture, since it is difficult to encase the threads passing through with plastic in a satisfactory manner by spraying or immersion.



   The object on which the invention is based was therefore to design the known measuring tapes made of plastic with a layer of threads running next to one another in the longitudinal direction of the tape so that they have the greatest possible strength with the smallest possible thickness, that they are produced in a relatively simple and inexpensive manner and at the same time their two sides of the tape can have smooth or almost smooth surfaces, depending on your choice, without additional processing and that it is also possible, if necessary, to give the two sides of the tape different colors and thus avoid mix-ups.

   This is achieved according to the invention in that the position of these threads is covered on both sides by a strip-shaped film made of thermoplastic material and the two film strips are welded to one another with the threads embedded.



   When the plastic foils are welded together while the foils are simultaneously pressed onto one another, the threads form a firm bond with these foils, so that the tensile and tear strength of the band obtained is extremely high, at least greater than when the plastic is coated with plastic by spraying or dipping Fiberglass tapes are where there is a risk that their embedded threads do not form a sufficiently non-slip connection with the plastic cover.

   A particular advantage of the tape according to the invention is that it is much easier and cheaper to manufacture than those whose insert is coated by spraying or immersion and that all that is necessary to achieve differently colored tape sides is to add differently colored tape-shaped foils when adjusting the tape use.



   The threads embedded in plastic can be made of glass fibers, but also metal, e.g. B. bronze or textile material such as linen, cotton or rayon exist. The plastic foils covering the thread insert can also be formed by a single strip of corresponding width, which is bent in its center line and whose longitudinal halves located on both sides of this bending line are welded to one another.



   Further advantages of the tape according to the invention emerge from the following description of an exemplary embodiment which is shown in the drawing in the form of a section partially torn away in an oblique view.



   This exemplary embodiment of the measuring tape according to the invention consists of two tape-like foils 1 and 2 made of thermoplastic material lying on top of one another, between which a layer of six essentially inextensible threads 3 lying close to one another or at a slight mutual spacing is arranged. The width of the foil strips exceeds the width of the position of the threads. By mutually welding the two film strips 1 and 2, they are firmly connected to one another and to the threads 3.
