Abstract: An apparatus for stripping continuously a solid mass in a strip from a two roll mill comprising a frame; knife means at a first end of said frame adapted to cut a strip of solid mss from said two roll mill; first roller means adapted to receive the cut strip and pass it through a dusting means which applies a non-stick powder on said cut strip. Second roller means in said dusting means adapted to pass said dusted cut strip through such dusting means into a packaging container. There is also envisioned a novel means for fixing the distance of the knife means from the two roll mill with precision.
