Abstract
A device for producing intertwining knots in a multifilament thread has a rotating nozzle ring with an encircling guide groove on an outer casing and an encircling sealing surface on an inner casing. At least one nozzle bore opens radially into the guide groove and passes through the nozzle ring. The nozzle ring is guided on a stator that has an encircling sliding surface on its periphery for guiding the nozzle ring and that forms a pressure chamber having a chamber opening that opens into the sliding surface. The sealing surface of the nozzle ring interacts with the sliding surface of the stator in order to provide air sealing. The nozzle ring is formed in a pot-like manner with an end wall having a disc-like end sealing surface which interacts with an end sliding surface formed on an end side of the stator to provide air sealing.
