A single-page dictionary entry describing machines for forming hat bodies from wool or fur. It explains an older method of winding carded wool slivers onto a revolving cone, and the later machine patented by H. A. Wells in 1846, which uses feeding belts, a rotating picker, a fan-blower and a perforated cone to deposit fur. It then outlines how the formed body is covered and immersed in hot water to felt it. A cross-sectional diagram (Fig. 2431) is included.
