  Natte de protection pour couches de forçage et analogues et son procédé de production . 
 EMI1.1 
 --------------------------- - 
Le but de la présente invention est de fournir des nattes pour la protection de couches de forçage et analogues, nattes qui sont peu coûteuses en ce qui concerne les frais de production, qui sont durables et conviennent spécialement d'une autre manière pour ce but. 



   La caractéristique principale de l'invention consiste en ce que la natte participe de la forme d'un tissu dont la trame consiste en fils filés de fibre de bois, tandis que la chaîne consiste en fils de fer doux ou en fils de matières semblables. 



   La fibre de bois à utiliser est d'abord trempée pendant plusieurs heures dans une solution de borax consistant en 1 partie de borax pour 100 parties d'eau, après quoi elle est filée dans une machine spéciale en des fils d'épaisseur conve- nable. Immédiatement avant le filage, il est efficace de tremper la fibre de bois dans de l'eau pure. Avec les fils filé s, une natte est alors faite dans un métier spécial avec   l'emploi   de fils ae fer doux ou en d'autres matières come 
 EMI1.2 
 chaîne, les fils de fibres de bois étant utilisés comme trame.

  Protective mat for forcing layers and the like and method of production thereof.
 EMI1.1
 --------------------------- -
The object of the present invention is to provide mats for the protection of forcing layers and the like, which mats are inexpensive in terms of production costs, which are durable and otherwise are especially suitable for this purpose.



   The main feature of the invention is that the mat takes the form of a fabric whose weft consists of threads spun from wood fiber, while the warp consists of soft iron threads or threads of similar materials.



   The wood fiber to be used is first soaked for several hours in a borax solution consisting of 1 part of borax to 100 parts of water, after which it is spun in a special machine into threads of suitable thickness. . Immediately before spinning, it is effective to soak the wood fiber in pure water. With the spun yarns, a mat is then made in a special loom with the use of soft iron yarns or of other materials such as

 warp, the yarns of wood fibers being used as weft.
