   Verminderung   lässt sich nur durch   unverhältnismässige   Vergrösserung der   Seildicke   ausgleichen, woraus aber wieder eine ungleichmässige Anspannung der Fäden infolge ihrer ver-   schiedenen   Entfernung von der Achse, also auch der grossen Verschiedenheit der Neigungswinkel ihrer Schraubengänge resultiert, so   dasss   die Tragfähigkeit solcher Seile, auf gleich grossen Querschnitt berechnet, mit der Dicke des Seiles abnimmt. 



   Die vorliegende Erfindung betrifft ein Verfahren, durch weiches die genannten Nachtheile beseitigt und vollkommen runde Seile hergestellt werden, die bei gleichem tragendem Querschnitt, wie jene der auf gewöhnliche Weise hergestellten Seile viel geringere Dicke besitzen. 



  Dieses Verfahren kennzeichnet sich dadurch, dass die Seile, anstatt wie bisher aus Litzen,   aus concentrisch liegenden   Schichten von Fäden hergestellt worden, von welchen jede Schichte eine mit Bezug auf die vorhergehende Schichte entgegengesetzt gerichtete   Drohung   erhält, wie aus Fig. 1 der beiliegenden Zeichnung ersichtlich. 



   Bei der mit Hilfe der gebräuchlichen Vorrichtungen bewirkten Herstellung solcher Seile wird um einen   aus mehreren Fäden zusammengedrehten Kern (Seele) a   eine concentrische Schichte b von Fäden gelegt, die direct von den Spulen weggeführt werden. 



  Diese den Kern   schalenartig umhüllende Fadenschicbte   wird in entgegengesetzter Richtung zu der Drehrichtung des Kernes gedreht. Um diese Schichte b wird dann eine zweite Fadenschichte c concentrisch gelegt, welche eine entgegengesetzte Drehrichtung mit Bezug auf die vorhergehende Fadenschichte erhält. Auf diese Weise werden so viele concentrische Schichten von Fäden, deren Drehsinn abwechselnd positiv und negativ ist, übereinander angebracht, bis das Seil die   gewünschte   Dicke hat. 



   Als Fasermaterial zur Herstellung dieser Rundseile kann ausser Hanf auch Werg, mania oder ein anderer zur Herstellung von Seilen verwendbarer bekannter vogetabilischer Faserstoff dienen.

 EMI1.1
 
 EMI1.2
   Reduction can only be compensated by a disproportionate increase in rope thickness, which again results in uneven tension of the threads due to their different distances from the axis, i.e. also the great difference in the angles of inclination of their screw threads, so that the load-bearing capacity of such ropes is of the same size Cross-section calculated, decreases with the thickness of the rope.



   The present invention relates to a method by which the aforementioned disadvantages are eliminated and completely round ropes are produced which, with the same load-bearing cross-section, have a much smaller thickness than that of the ropes produced in the usual way.



  This method is characterized in that the ropes, instead of being made of strands as before, are made of concentric layers of threads, of which each layer receives an opposite threat to the previous layer, as can be seen in FIG. 1 of the accompanying drawing .



   In the manufacture of such ropes effected with the help of the usual devices, a concentric layer b of threads is placed around a core (core) a twisted together from several threads, which are led away directly from the spools.



  This thread layer enveloping the core in a shell-like manner is rotated in the opposite direction to the direction of rotation of the core. A second thread layer c is then placed concentrically around this layer b, which is given an opposite direction of rotation with respect to the previous thread layer. In this way, so many concentric layers of threads, the direction of rotation of which is alternately positive and negative, are attached one above the other until the rope has the desired thickness.



   In addition to hemp, tow, mania or another known vogetabilic fiber material that can be used for the production of ropes can serve as fiber material for the production of these round ropes.
