The apparatus for pneumatic manufacture of yarn from natural or synthetic fibers employs a non-rotational chamber, has an insert which contains a central yarn discharge channel, circumferential ducts to supply air as well as a fiber delivery channel at the upper portion. The insert has the guides arranged about its lower periphery, the bottom edges of these guides being screened with a shielding ring, and the air supply air ducts are located beneath the upper edges of the guides. In an alternative design, the guides are associated with the distribution ring, whose lateral inner face is in common with the insert wall and guides to thereby form air passages.
An apparatus for the pneumatic manufacture of yarn employing a non-rotational spinning chamber closed at one end having cylindrical insert means provided with a yarn discharge channel disposed therein, circumferential supply air ducts for introduction of a vacuum source into the other end of the chamber, fibre delivery channel means formed of said chamber and provided upstream of an inlet of the yarn discharge channel, said apparatus including:
