Abstract
An air jet spinning arrangement includes an essentially hollow cylindrical vortex chamber, whose peripheral wall forms a supporting surface for a peripheral surface of a rotationally symmetrical insert in the running-in area of the staple fiber strand. A number of air jet slits are worked into the peripheral surface of the insert, which air jet slits are completed to form closed compressed air channels by way of the supporting surface. The nozzle-like mouths of the compressed air channels are arranged on the front side of the insert facing the vortex chamber. The design of the air jet slits resemble a multiple-start thread.
