Abstract
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.
