Thread-fin′ish-er.

A machine in which thread is treated to give it a smooth and polished surface. It usually consists of a sizing and drying operation, which smooths down the fluff of the fiber and imparts a hard, glossy surface.

Thread-finishing machine.

In the example (Fig. 6398) the thread is shown as going from left to right; from the bobbins b b to the size-bath e, the wipers g, steam-chests h i, to the guides k′, which deliver it to spools in the winding-frame on the right.

In Fig. 6399, the thread proceeds from the spools on stand W by a guide j, thence is coiled around the rollers d d, which are in a frame having a horizontal reciprocating motion to rub the threads, in order to harden and round and at the same time rub the fluff from the thread. It then passes by a reciprocating guide-bar p to the receiving-spool N. See also thread-frame; thread-polisher.

1877.
