While On Form Patents (Class 28/124)
  • Patent number: 8869361
    Abstract: Disclosed are a method and an apparatus for applying a compaction pressure to a fabric during formation of a fabric preform. One end of the fabric is applied to the form having a central axis. The form with the fabric applied thereto is at least partially surrounded with a film. This film extends along a film path to the form and around at least a portion of the form. The fabric and the film are fed onto the form such that the fabric is wrapped around the form to create the fabric preform while the film is fed around the form. A vacuum is drawn to evacuate a gas from between the form and the film, thereby pressing the film onto the fabric and applying the compaction pressure to the fabric.
