Abstract
The present invention reveals an improved unitary or one-piece acoustical cabinet grille frame and an improved method for making the one-piece grille frame. In the unitary acoustical cabinet grille frame, a sound-transmissible fabric is integrally bonded or fused to serrations on an inner wall in a slot within a shaped plastic face. In the method for manufacturing the one-piece acoustical cabinet grille frame, a sound-transmissible fabric is placed in contact with a shaped plastic face. A heated fusion blade having the configuration of the slot is placed in contact with the sound-transmissible fabric. The fabric is forced into contact with plastic serrations on an inner wall in a slot and the plastic serrations are plasticated or melted. The sound-transmissible fabric is then fused with the plastic. Finally, the heated fusion blade is removed from the slot and the plastic is allowed to cool.
