| SLASHING MACHINE. This is a machine for sizing the threads. In a slasher, the threads from a number of warping beams are first combined into one sheet and then plunged into a trough filled with size which is kept at a boiling temperature, and next squeezed between two pairs of rollers The sheet of yarn almost encircles two steam-heated cylinders. This quickly dries the yarn. The yarn is next measured, passed above and below rods which separate the threads which are wound upon a loom beam.

THE LOOM. The first loom was set up in Dantzig in 1661. To prevent such a machine from injuring the poor people the authorities in Poland suppressed it and privately strangled or drowned the inventor. In 1733 John Kay, of England, invented a fly shuttle. Before Kay's time, the shuttle was shot by hand across and through the warp threads from side to side. Kay's loom forms the basis of all modern power looms. The above picture presents the marvelously ingenious power loom of the present day.

| TEASELING MACHINE. This machine takes its name from the teasel, a plant which has a large flower-head covered with a stiff, prickly bur. This is used for raising the nap on woolen cloth. In the center of the machine is a large cylinder, as we see here, which carries little hooks like a teasel bur, for raising the nap on woolen cloth. As we see here, the cloth is passed over this cylinder and descends in folds.

SHEARING MACHINE. This is a machine for cutting off the nap that is too long, making it smooth and even.
