Equipment for pneumatic manufacture of yarn

摘要

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.
