    摘要： Method to delete and reintroduce individual yarns as needed when they are being fed to a textile process by cutting an individual yarn, that is being forwarded to the process, rapidly to prevent producing a disruptive tension change in the process or in other yarns being forwarded to the process to produce an upstream cut end of an individual yarn; holding the upstream cut end of said individual yarn in an elongated condition at a ready position for reintroducing to the process; and reintroducing said yarn at said ready position to the textile process according to the following steps; metering said individual yarn from said source at a controlled rate; passing said cut end of yarn with a first individual yarn forwarding jet for forwarding said cut end from said ready position and maintaining said cut end of yarn in an elongated condition during said metering; directing said elongated, cut end of yarn in a path past an individual yarn cutter; passing for forwarding said elongated cut end of yarn from said cutter and along an individual yarn path, and maintaining said cut end of yarn in an elongated condition during said passing; and converging said elongated, cut end of yarn with a plurality of individual yarn paths for said plurality of yarns for forwarding said yarn to said textile process.

    摘要翻译： 当通过切割单独的纱线被快速地转送到该方法中时，根据需要删除和重新引入单根纱线的方法，以防止在该方法中或其它纱线中产生破坏性的张力变化被转发到 生产单纱的上游切割端的工艺; 将所述单根纱线的上游切割端在延长状态下保持在就绪位置以重新引入到该过程中; 并根据以下步骤将所述纱线重新引入所述纺织工艺的所述就绪位置; 以受控的速率从所述源计量所述单根纱线; 使用第一单独的纱线前进喷嘴使所述纱线的切割端通过，以将所述切割端从所述就绪位置传送，并且在所述计量期间将所述纱线切割端部保持在细长状态; 将纱线的所述细长的切割端引导通过单独的纱线切割器; 使所述细长切割的纱线从所述切割器沿着单独的纱线路径传送，并且在所述通过期间将所述纱线切割端部保持在细长状态; 并且将所述细长的切割端与所述多根纱线的多条单独的纱线路线会聚，用于将所述纱线转送到所述织物过程。
