When weaving, we can change the size of the loop (stitch) or skip the stitch. In addition, the diameter of the take-up roll can be changed completely or partially to change the size of the loop.

Abstract

L'invention se rapporte à une matière de couverture destinée à être fixée à la surface d'un article en métal ou en résine pour le renforcer, ladite matière comportant des fibres agencées de manière à être orientées le long de la direction souhaitée de renforcement. Cette matière de renforcement peut être un tricot fabriqué au moyen d'une machine à tricoter possédant un mécanisme d'insertion qui peut être utilisé pour tricoter ensemble, sous la forme d'une ligne droite, une fibre de renforcement telle qu'une fibre de carbone, et un fil d'insertion, sur toute la largeur ou la longueur dans des directions respectives. Ledit tricot est fabriqué au moyen d'un fil élastique utilisé en tant que fil de trame bouclé. Ladite matière de renforcement peut également être un tissu qui est fabriqué au moyen d'un fil de renforcement et d'un fil élastique servant respectivement de fil de chaîne et de fil de trame. Ledit tissu est fabriqué de sorte que les fibres de renforcement sont positionnées à proximité de l'article à recouvrir grâce à la force d'allongement et de rétrécissement du fil élastique. Des exemples de la fibre de renforcement décrite ci-dessus incluent des filaments fibreux assemblés de façon à former un ruban plat ou un élément ayant une épaisseur ou une largeur variable, et une bande ou un cordon que l'on fabrique en alignant des filaments fibreux à la surface d'une feuille, puis en les fixant et en les coupant. L'utilisation de cette matière de couverture dans un but de renforcement permet aux fibres de renforcement d'entrer facilement en contact étroit avec un article possédant des surfaces courbes variées. De plus, le fait d'utiliser une résine d'enrobage ou analogue pour les fixer permet de renforcer uniformément ledit article.
