ABSTRACT:
Variegated detergent bars are made by mixing together pieces of soaps of contrasting colors in a vacuum zone and plodding the mixture in such manner as to fuse the different soaps together but maintain colors separate, thereby producing a desired pattern therein, preferably resembling marble. The pattern is controllable by variations of the proportions of material charged, plasticities thereof, speeds of the worms, design of the compression-extrusion head and preferably, by extruding the soaps through small openings in a plate after the final plodder worm, cutting the extrudates and imparting transverse or radial motions to them before final extrusion.
Also described are plodding and extruding apparatuses utilized to practice the variegating process.
