willow
1. A machine consisting essentially of two
rotating drums having spikes attached to their
interior surfaces. The willow is used to tear raw
material, e.g., rags, waste paper, etc., for use
in making paper. The willow frequently utilizes
air currents to remove dust from the usable
papermaking material. Also called a "devil." 2. A
long grain in leather. The willow grain is
produced by drawing the leather from head to butt
over a dull blade. (130 , 156 , 172 )
