Fulling Mill

After the wool was turned into cloth, the cloth was taken to a mill where it was fed through rollers (turned by a waterwheel) which plucked the cloth to soften and "fatten" the fibers. Attached to the rollers were teasels, a plant with burrs on it, which pulled the woolen fibers (hence, teasing).

An example of a fulling mill is this one in Rowley, now known as the Jewell Mill.
