Title (EN) PRODUCTION OF WARP/WEFT SHEET
(FR) PRODUCTION D'UNE NAPPE DE CHAINE/TRAME
Abstract:
(EN) A warp sheet (5) comprising individual warp yarns is fed forward. A plurality of weft yarns (9) are laid over the warp sheet. These weft yarns (9) are trapped between filamentary elements (12) and the outer warps of the warp sheet (5). By directing the elements (12) and outer warps outwardly with respect to the remainder of the sheet (5) the weft yarns are tensioned prior to the yarns being introduced into a layer of adhesive. The adhesive is cured to form the material layer.
(FR) Une nappe de chaîne (5) comprenant des fils de chaîne individuels est avancée. Une pluralité de fils de trame (9) est couchée sur la nappe de chaîne. Ces fils de trame sont emprisonnés entre des éléments filamenteux (12) et les chaînes extérieures de la nappe de trame (5). On peut tendre les fils de trame en orientant les éléments (12) et les chaînes extérieures vers l'extérieur, avant que les fils ne soient introduits dans une couche d'adhésif. L'adhésif est polymérisé pour former la couche de matière.
