Device for producing intertwining knots

摘要

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.

主权项

1. A device for producing intertwining knots in a multifilament thread comprising:
a rotating nozzle ring having an encircling guide groove on an outer casing, an encircling sealing surface on an inner casing, and an end wall with an end sealing surface; at least one nozzle bore that opens radially into the guide groove and passes through the nozzle ring; a stator having an encircling sliding surface on its periphery for guiding the nozzle ring, wherein the encircling sealing surface of the nozzle ring cooperates with the encircling sliding surface of the stator for air sealing and wherein the stator has an end sliding surface on one end side that interacts with the end sealing surface of the nozzle ring in order to provide air sealing; and, a pressure chamber having at least one chamber opening that opens into the encircling sliding surface, wherein at least one of the encircling sliding surface and the end sliding surface of the stator have a plurality of grooves arranged next to one another.
