The cylindrical, non-rotational chamber has one closed end and an insert incorporating a yarn discharge channel. Also provided as part of the chamber are peripherally disposed air supply ducts and a fiber delivery channel. The chamber is provided with a cylindrical element and air guides disposed under a fiber ring arranged at the chamber outlet.
