ABSTRACT:
An apparatus and method are provided for forming elongated solid shapes from solid flowable materials such as metal powders, metal shot, fragments or segments of metal in a weldable condition by continuously feeding same to die means which includes two or more power rotated rolls or rollers between which the flowable material is fed and compressed to define its shape. In one form the flowable material or particles may be cold pressured welded into the shape defined by the surfaces of the rolls and their spacing. In another form, heat may be generated within or transferred to the material between the rolls by induction or resistence heating means disposed within or adjacent to the rolls, wherein the heat and the high pressure applied to the material by the rolls serves to fuse or weld the material fed therebetween into a solid porous or non-porous mass as it is fed through the rolls. Heat generated within the compressed material by the compressive force of the rolls thereon may also serve to fuse the material into a solid porous or non-porous mass.
