SETT OCH ANORDNING ATT TILLVERKA TVINNAT GAR AV FLERA PARTER

摘要

In a spinning operation in which two strands are fed from separate nip positions and are twisted together into a single ply at a convergence point, twist is incorporated into the single strands by intermittently blocking the twist at a position between the convergence point of the strands and the point of application of the twist. The operation can be performed by a standard spinning frame modified to incorporate a convergence guide and a twist blocking device.
