ABSTRACT:
A spinning machine, preferably an open end spinning machine, having a conduit associated therewith for distributing a flow of conditioned air along a predetermined flow path in which the conditioned air is caused to flow in a direction directly toward and across the rapidly rotating, heat-generating element (e.g., a rotor disposed in a spin box), with a portion of the conditioned air flowing in and around the rapidly rotating element to absorb heat from the same, and with another portion of the conditioned air flowing across the length of fibers fed to the spinning machine and across the yarn produced at the spinning machine to moisturize the length of fibers and yarn. A return duct is located above the spinning machine and has a negative pressure created therein for causing the conditioned air, after it has absorbed heat from the rotating element and conditioned the length of fibers and the yarn, to flow upwardly from the spinning machine and entrain microdust and similar particulate matter therein and the conditioned air is then received by the return duct.
