Abstract
Nozzle (1) for manufacturing knotted yarn (11), having a yarn duct (2) in which knots are producible with the aid of air entanglement. The nozzle includes at least one air bore (3) having a longitudinal axis (A), which merges with the yarn duct (2) in a merging opening (4). Air is introducible into the yarn duct (2) through the air bore. The longitudinal axis (A) of the air bore (3) is disposed at an angle of less than 90°, preferably 65-85°, particularly preferably 78° in relation to a conveying direction (B) of the knotted yarn (11). A baffle face (5) is configured on the opposite side of the merging opening (4) of the air bore (3) in the yarn duct (2), so as to be substantially perpendicular in relation to the longitudinal axis (A) of the air bore (3).

1-18. (canceled)
A nozzle for manufacturing knotted yarn, having a yarn duct in which knots are producible with aid of air entanglement, and having at least one air bore having a longitudinal axis (A),
- wherein said air bore merges with the yarn duct in a merging opening and air is introducible into the yarn duct through the air bore,
- the longitudinal axis (A) of the air bore is disposed at an angle of 90° in relation to a conveying direction (B) of the knotted yarn, and at least one of:
- a region of an entry opening of the yarn duct is constricted in relation to a cross section of the yarn duct in a region of the merging opening of the air bore, and/or
- an exit opening of the yarn duct is widened in relation to a cross section of the yarn duct, in the region of the merging opening of the air bore, and a baffle face is configured on an opposite side of the merging opening of the air bore in the yarn duct,
- such that a larger net amount of air dissipates via the exit opening than via the entry opening.
The nozzle for manufacturing knotted yarn, having a yarn duct in which knots are producible with aid of air entanglement, and having at least one air bore having a longitudinal axis (A),
- wherein said air bore merges with the yarn duct in a merging opening and air is introducible into the yarn duct through the air bore,
- a step is configured between an entry opening of the yarn duct and the merging opening of the air bore, on a side of the yarn duct which is opposite the air bore, and
- the step leads away from the merging opening, in the conveying direction (B), such that yarn is deflectable around an edge of the step.
A method for manufacturing knotted yarn within a yarn duct of a nozzle, with the aid of air entanglement, wherein, through at least one air bore having a longitudinal axis (A), air is introduced in a direction of the longitudinal axis (A) at an angle of 90° in relation to a conveying direction (B) of the knotted yarn, so as to be directed onto a baffle face, said air bore merges with the yarn duct,
- wherein, on account of at least one of:
- a constriction in the region of the entry opening of the yarn duct in relation to a cross section of the yarn duct in the region of the merging opening of the air bore and
- a widening of the exit opening of the yarn duct in relation to a cross section of the yarn duct in the region of the merging opening of the air bore,
- a larger net amount of air dissipates via the exit opening than via the entry opening.
A method for manufacturing knotted yarn, within a yarn duct of a nozzle, with aid of air entanglement, wherein, through at least one air bore having a longitudinal axis (A), air is introduced, the air bore merges with the yarn duct, wherein with the aid of a step, which is configured between an entry opening of the yarn duct and the merging opening of the air bore in the yarn duct on the opposite side of the air bore, wherein the step leads away from the merging opening in the conveying direction (B), such that yarn is deflected around an edge of the step on account of air from the air bore.
