An assembly and method is provided for scarfing a fibrous material with an assembly that provides automated control of a scarf gap. The assembly includes a moveable mount, a driven scarfing roll coupled to the moveable mount, and a scarfing roll lifting assembly coupled to the moveable mount. A first sensor senses contact between the scarfing roll and an external surface and a second sensor senses position of the scarfing roll when information is received from the first sensor that contact of the scarfing roll with the external surface has occurred. A control unit operates the scarfing roll lifting assembly to position the scarfing roll at a desired scarf gap measured from the contact position. The scarfing roll is positioned based on an identified high point of the external surface, such as the external forming surface of a forming drum.
