Flyer.
1. A contrivance with arms which revolves around the bobbin in the
bobbin and fly frame, or the
throstleframe, which machines draw and twist the
sliver into a
roving, or the latter into
yarn.

Flyer. |
The
flyer fits on to the top of the spindle, and one arm (in the
bobbin and fly frame) is made hollow to form a passage for the yarn, which enters at the cup above the top of the spindle, and after a turn or two round the end of the arm is distributed on the bobbin.
In the throstle-frame the roving entering above is wound
round the arm of the
flyer, instead of passing
through a
tubular arm. See throstle.
The flyer rotates with the spindle, and their rotation gives the twist to the yarn.
The bobbin is independent of the spindle motion, but in roving-machines has a surface motion equal to the rate of delivery of the yarn from the drawing-rollers.
See roving. The same also occurs in the bobbin and fly frame (which see).
In the
throstle, the winding occurs by the detention of the bobbin, which rests on the
copping-rail, the bobbin being dragged around by the yarn proceeding from the end of the
flyer, the resistance to revolution on the part of the bobbin effecting the winding.
See throstle; equatorial box.
2. The fan-wheel on the vane of a windmill cap which rotates the latter as the wind veers.
See cap.
3. A step in stairs that ascend in one inclined plane, without winding.
A straight reach of stairs.
A
flight.
4. (
Printing.) A vibratory rod with fingers which take the sheet of paper from the tapes and carry it to the delivery-table, the sheet resting flatly against the flyer-fingers by the resistance of the air. See fly.
