<p>Quantity production of friction nuts prepared for subsequent fusion of thermoplastic resin particles deposited in thread grooves therein, in which the nuts are supported with their axes vertical, a fluid slurry of the particles in a liquid carrier is introduced into the threaded interior of the nuts to fill the threaded opening, including the thread grooves therein, to a predetermined level from the bottom of the nuts. Excess slurry is then drained from the bottom ends of the openings. In order to leave the threads clear of obstruction at the bottom of the nut, the deposited slurry, after partially drying, is removed from the bottom thread convolutions by repeatedly inserting and withdrawing a sponge-like material directly into and out of the lower end of the thread opening, or by strongly agitating a small quantity of water in the lower part of the threaded opening.</p> |
