  • Patent number: 5321942
    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.

  • Patent number: 4857090
    Abstract: An energy conservation system for cooling and conditioning air, particularly air at elevated temperatures which is discharged from the rotors of open-end spinning machines. The air is directed along a predetermined flow path in which a first stage cooling zone is established, which utilizes one or more cooling coils through which flow a heat exchange fluid that is cooled by an externally located cooling tower. The system includes a second stage cooling zone comprising an air washer in which water is sprayed into the air stream, such water being chilled in part by a mechanical refrigeration unit. The air washer preferably includes two spray pipes, one being located upstream of the other, with the downstream spray pipe receiving some liquid chilled by the refrigeration unit, and with the upstream spray pipe receiving its spray liquid from the discharge collected from the downstream spray pipe.
