ABSTRACT:
Soap worked in a plodder with introduction of a color dye for color striation of the extruded column is extruded through a die plate that has a rectangular opening corresponding to the major face dimensions (length and width) of the product bar so that the extrusion grain is perpendicular to the major faces, and the extruded column is severed at distances equal to the product bar thickness to provide blanks that are pressed in a direction parallel to the extrusion grain to form the product bar. Special locations for color introduction are provided and a unique "carrara" marble effect is produced in the bar.
