ABSTRACT:
Method and apparatus for removing flash from an article are provided. The method features the steps of striking the flash with a first lash at least partially along the side of the lash with enough force to initiate separation of the flash from the article while simultaneously supporting the lash sufficiently to prevent the lash from bending sharply on itself and breaking; these steps are repeated until the flash has been completely separated from the article. The apparatus comprises at least one lash with sufficient support to prevent it from bending on itself and breaking, and means for rotating the lash about a central axis for contact with the flash.
