Abstract
Screw blanks are loaded automatically into a rotatable tub while the latter is in an inclined loading-washing position. As the tub rotates, a washing liquid is sprayed into the tub to clean residue from the blanks and to wash chips from the blanks, the liquid and the chips escaping through a gap of adjustable width at the bottom of the tub. The tub then is swung to a vertical position and is rotated at a much faster speed to dry the blanks. Thereafter, the tub is tilted to an unloading position and the blanks are automatically dumped from the tub.
