A dictionary entry on the willowing machine (willow, willower) from Knight's American Mechanical Dictionary. It defines the machine for flax, cotton and wool, and describes how a spiked drum opens fibers and removes dirt and impurities. Two figures (Figs. 7214 and 7215) show the cotton willow and willower, with operating details such as drum speed and output. It also covers alternate names, the origin of the term, and where willowing sits in cotton processing before batting and carding.
