Title
(EN) A BIAS YARN ASSEMBLY FORMING DEVICE
(FR) DISPOSITIF PERMETTANT DE CONSTITUER UN ASSEMBLAGE DE FILS BIAIS
Abstract
(EN)
A device for forming from a warp sheet (17) a bias yarn assembly comprising two superposed bias yarn sub-assemblies in which the bias yarns of one sub-assembly are inclined to the bias yarns of the other sub-assembly and in both of which the bias yarns are inclined to the warp feed direction includes a yarn transfer mechanism (18) having a lower yarn guide member (21) with upstanding yarn guide elements (261) which extend through the thickness of the warp sheet (17) and define warp yarn guide openings (27) through which the warp yarns of the warp sheet (17) pass and which hold the warp yarns in positions spaced apart in the weft direction and an upper yarn transfer member (22) which includes yarn guide elements (281) which extend downwardly and which define transfer openings (29) for the reception of yarns of the warp sheet (17) from the yarn guide openings (27) for transfer to other yarn guide openings (27). The warp yarns of the warp sheet (17) are arranged to pass through eyelet elements (32) which are supported by the guide elements (261, 281) for sliding movement along the guide elements and which protect the yarns during yarn movements from one opening in one member (21, 22) into a registering opening in the other member (21, 22).
(FR)
L'invention concerne un dispositif permettant de constituer un assemblage de fils biais à partir d'une nappe d'ourdissage (17). Cet assemblage est composé de deux sous-assemblages superposés dans lesquels les fils biais de l'un sont inclinés vers les fils biais de l'autre. Les fils biais des deux sous-assemblages sont inclinés dans le sens d'alimentation des fils de chaîne. Le dispositif comporte un mécanisme de transfert de fil (18), comprenant un guide-fils inférieur (21) avec des éléments guide-fils verticaux (261) qui prennent toute l'épaisseur de la nappe d'ourdissage (17), définissent les ouvertures du guide-fils de chaîne (27) à travers lesquelles passent les fils de chaîne de la nappe d'ourdissage et maintiennent séparés les fils de chaîne dans le sens de la trame. Il comporte également un élément supérieur de transfert de fil (22) comprenant des éléments guide-fils (281) qui s'étendent vers le bas et délimitent les ouvertures de transfert (29) pour la réception des fils de la nappe d'ourdissage (17) venant des ouvertures du guide-fils (27) en vue du transfert vers les autres ouvertures de guide-fils. Les fils de chaîne de la nappe d'ourdissage (17) sont disposés de manière à passer au travers d'÷illets (32), supportés par les éléments du guide-fils (261, 281) en un mouvement glissant le long des éléments guide; ces ÷illets protègent les fils durant leur passage d'une ouverture dans un élément guide-fils (21, 22) vers l'ouverture qui coïncide dans l'autre élément guide-fils (21, 22).
