Patent ID: 7353575

Claim:
A method of producing knotted yarn from smooth and textured filament yarn in a continuous yarn channel of an interlacing nozzle, the yarn channel having an axis, the method comprising: supplying primary air into the yarn channel through a main bore directed centrally into the yarn channel for providing interlacing flow; supplying secondary air into the yarn channel through at least one auxiliary bore arranged at an axial distance from the main bore; and wherein the primary air is supplied into the yarn channel perpendicularly to the yarn channel axis or only with a slight angular deviation from a plane perpendicular to the yarn channel axis, in such a way that the primary air only has a slight conveyance effect or a minor effect against the conveyance; and wherein the secondary air is supplied to the yarn channel at an angle inclined with respect to a plane perpendicular to the axis of the yarn channel and in a direction different from the direction along which the primary air is supplied, for supporting the interlacing flow.
