Abstract
A feeder for delivering streams of molten mineral material for attenuation into filaments having an electrically conductive bottom wall with orifices formed therein. The molten material in the feeder passes through the orifices and is delivered as streams for attenuation into fibers. Extending from the bottom wall, in a direction generally normal to the plane of the bottom wall, are electrically conductive side and end walls. Positioned within the feeder generally parallel to the plane of the bottom wall is a molten material conditioning means. On the exterior surface of each of the end walls there is a terminal for conducting electrical energy to the feeder to heat the walls and molten material conditioning means of the feeder and thereby condition the molten material in the feeder. Each of the terminals has an inner portion attached to the end walls at the location of the molten material conditioning means. The inner member is positioned so that it is generally parallel to the plane of the bottom wall. Each of the terminals also has an outer portion, that is attached to the inner portion, in spaced apart relationship from the end walls. And the outer portion extends from the inner portion towards the bottom wall in a direction generally normal to the plane of the inner member.
