Device for producing interlaced knots

摘要

A device for producing interlaced knots in a multifilament thread is described. The device includes a rotating nozzle ring having a circumferential guide groove and a plurality of nozzle bores opening radially into the base of the guide groove. A stationary pressure chamber, having a chamber opening and an air connection, is associated with the nozzle ring, wherein by rotation of the nozzle ring the nozzle bores can be connected in turn to the chamber opening of the pressure chamber. To permit an intensive air treatment of the thread, the dimension of the chamber opening in the pressure chamber and the spacing of adjacent nozzle bores on the nozzle ring are designed such that as the nozzle ring rotates a plurality of nozzle bores are simultaneously connected to the chamber opening.

1. A device for producing interlaced knots in a multifilament thread comprising:
a. a nozzle ring, which includes a circumferential guide groove and a plurality of spaced apart nozzle bores opening radially onto a groove base of the guide groove; b. a stationary pressure chamber associated with the nozzle ring and including an air connection; and, c. a chamber aperture that extends radially over the stationary pressure chamber an amount defined by an aperture angle (α), wherein the chamber aperture and the nozzle bores are configured such that, upon rotation of the nozzle ring, at least two nozzle bores are simultaneously fluidly connected with the chamber aperture.
