Applying machine oil to all oiling holes and joints where one parts rub against another. One drop of oil is enough for each point. While oiling turn the flywheel back and forth to help the oil flow to the moving parts. It is essential to oil the shuttle race. After oiling the points on the head of the machine, tilt the machine head back to oil the parts on the under side. On a treadle machine, the belt will have to be released before tilting the machine head back. Do not forget to oil the pivots of the treadle. When the machine has been thoroughly oiled, wipe away excess oil and run it slowly for several minutes on a waste piece of material. Place a scrap of fabric under the presser foot and lower the needle before closing. The fabric will absorb the excess oil that will drain down through the machine and will prevent formation of oil spots on the fabric.

The polymer chips are melted by heat in an autoclave and pumped to the spinneret. The hot syrupy solution is pumped through the spinneret. It emerges in strands which can be stretched like warm taffy. The size of the fiber is determined by the size of the holes and the speed with which the fiber is withdrawn from the spinneret. The fibers are cooled by air blown across them. By the drawing process either filament or staple fibers are prepared.
