The invention relates to tubular knitwear items complete with shoulder straps, braces and various openings for legs or arms manufactured preferably without the usual cutting and sewing operations. Through the appropriate selection of needles, in accordance with the jacquard design and with the operating cycle of the knitting machine, the invention allows the separation and automatic programmed resumption of stitch rows for defined areas or zones, thereby obtaining at least a complete opening (5, 5A) or brace, provided with simple or also double welt, depending on circumstances. Lastly, the invention eliminates nearly completely the usual and costly fabric scrap deriving from the current necessary cutting and sewing operations.

L'invention concerne des articles de bonneterie tubulaires munis de bretelles, d'attaches et de plusieurs ouvertures pour les jambes ou les bras, le procédé de fabrication de ces articles évitant de préférence les étapes habituelles de découpe et de couture. Cette invention permet notamment, grâce à une sélection d'aiguilles adaptée à la grille de jacquard destinée à être élaborée et au cycle de fonctionnement du métier à tricoter, la séparation et la reprise automatique programmée de rangées de mailles dans des aires ou zones définies. On obtient ainsi au moins une ouverture ou une attache (5, 5A), munie le cas échéant d'un revers simple ou double. Cette invention permet notamment d'éliminer presque totalement la production de chutes de tissus, généralement coûteuse, engendrée par les étapes de découpe et de couture.
