A process used to remove remnants of hair and hair sheaths, hair pigments, fat, and undesirable protein constituents, lime soaps, etc., from a skin when a very clean grain for both smoothness and level dyeing properties is required. A skin is usually scudded following unhairing, and, while it may be done following bating, it is always done before tanning. The process is carried out over the beam with a curved, blunt-edged knife, or, more often today, in a machine which squeezes and pushes the unwanted material (scud) out of the skin. (291 , 363 )
