Abstract
A mask for providing and protecting the shear edge of a mold from contact with oversprayed powder directed onto the wall of the mold cavity. The mask comprises an air flow duct having an opening located adjacent the shear edge of the mold. First and second air flow control members are adjustably mounted upon the duct adjacent the air flow opening. The first and second air flow control members have opposed edges spaced apart so as to define an air flow gap therebetween, which air flow gap is operable to direct an airstream from said duct onto the shear edge of the mold so as to effectively mask that shear edge from powder sprayed onto the cavity defining portion of the wall of the mold.
