A short dictionary entry on felting machines from Knight's American Mechanical Dictionary. It describes several types, including the fulling-mill, a vibratory-bed felter with reciprocating beds in a hot-water vat, a revolving felting machine with a cork-surfaced cylinder and steam-heated belts, and a felt-making machine that cards fiber and consolidates it under reciprocating platens. Engraved figures 1943 to 1946 illustrate each machine.
