Patent

CA 2650010

The invention relates to a temporary ground covering particularly for displacement on sandy, muddy or boggy ground comprising a woven structure formed of warp (6) and weft (7) and the weave thereof being such that each warp yarn (6) interlaces with the weft yarn (7) following, preferably and very approximately, half the intersections of the rows and columns of the weave, the warp yarn (6) being left in the remaining intersections, in order, for each warp yarn (6), to obtain at least one simple tight weave area followed by an area of floats, the alternation of the different abovementioned areas causing contractions of the weft yarn (7) creating a significant relief of the fabric thereby obtained. According to the invention, said covering comprises flat yarns (8) arranged over at least one part of the width of said woven structure on at least one of the surfaces thereof, each of said flat yarns (8) being taken, steadily or not, by weft yarns (7) placed at the ends of the projections of said woven structure surface.

L'invention concerne un revêtement de sol provisoire notamment pour le déplacement sur sol sableux, boueux ou marécageux comportant une structure tissée formée de fils de chaîne (6) et de fils de trame (7) et dont l'armure est telle que chaque fil de chaîne (6) s'entrecroise avec les fils de trame (7) suivant, de préférence et très approximativement, la moitié des intersections des rangées et colonnes de l'armure, le fil de chaîne (6) étant laissé dans les intersections restantes, en sorte, pour chaque fil de chaîne (6), d'obtenir au moins une zone d'armure simple et serrée suivie d'une zone de flottés, l'alternance des différentes zones susdites provoquant des resserrements des fils de trame (7) créant un relief important du tissu ainsi réalisé. Selon l'invention, ce revêtement comporte des fils plats (8) disposés sur une partie au moins de la largeur de ladite structure tissée sur au moins une de ses faces, chacun desdits fils plats (8) étant pris, régulièrement ou non, par des fils de trame (7) placés aux extrémités des saillies de ladite face de la structure tissée.
