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