Next, operators run machines that remove short fibers and foreign matter. If desired, these machines also combine different types of fibers together. Operators closely monitor the machines during this stage. If necessary, operators make minor repairs to the machines. Next, operators take the cans of sliver to spinning machines.
Some operators oversee machinery that makes manufactured fibers.
Operators mix wood pulp or chemical compounds in with other materials in order to make a liquid. Then they put the liquid in machines that extrude, or force, the liquid out through small holes, making fiber. Extruding and forming machine operators adjust the flow of the liquid through the hole and repair breaks in the fiber. They make minor adjustments to the machinery as well. The yarn, whether natural or synthetic, is put on machines that weave, knit, or tuft it into a product.
