ABSTRACT:
A false twisting unit consists of a body through which a passage is provided, which is surrounded by a cavity connected with said passage through tangential air ducts. A first channel passes through said body and opens into said cavity. Through said channel compressed air can be supplied, producing a rotating air column in the passage. A second channel passes through said body in such a way that liquid at or near the mouth of the tangential air ducts can be introduced into said passage.
