A one-page dictionary entry from Knight's American Mechanical Dictionary describing thread-polishing machines, which give thread its final gloss before spooling. It explains two machines: one using reciprocating rubber carriages with size-bowls (Fig. 6404), and another using sizing rollers, rotary disks with rubbing bars, and pressing rollers (Fig. 6405). Two engravings illustrate the machines.
