Profession twisting machine operator
Twisting machine operators tend machines that spin two or more fibres together into a yarn. They handle raw materials, prepare them for processing, and use twisting machines for the purpose. They also perform routine maintenance of the machinery.

- Realistic / Conventional
- Staple spinning machine technology
Technologies, operations, monitoring and maintenance of machines during the yarn spinning process.
- Types of textile fibres
The variety of textile fibres both natural such as wool and hemp and man-made or synthetic fibers.
- Cut filament
After the filament workpiece has been wound, cut the filament to release the workpiece.
- Maintain equipment
Regularly inspect and perform all required activities to maintain the equipment in functional order prior or after its use.
- Check quality of raw materials
Check the quality of basic materials used for the production of semi-finished and finished goods by assessing some of its characteristics and, if needed, select samples to be analysed.
- Tend spinning machines
Operate spinning machines keeping efficiency and productivity at high levels.
- Prepare raw materials
Prepare and measure the basic materials that are needed to produce goods and finished products.
- Set the operation speed of manufacturing machines
Define the adequate speed at which a manufacturing machine should operate in order to provide the required output in manufacturing processes.
- Convert textile fibres into sliver
Convert textile fibres into drafting sliver by working in the fibre opening, carding and drafting process.
- Prepare raw materials for man-made fibres manufacturing
Prepare for processing of man-made fibres, able to work on melt spinning process to produce thermoplastic fibres such as polyester, polyamide, polyolefins (e.g. polypropylene) and glass fibre. Work on a melt-extruder, where the liquid is forced through the spinner opening under pressure and cooled by a jet of air to form the filament. Able to work in spinning preparation (spin finish), generally applied at the bottom of the spinning duct. Able to work on dry spinning, to produce acetate, triacetate and polyacrylnitrile fiber dissolving polymer in a solvent, to extrude the dissolved polymer through a spinneret into a chamber of heated air or gas where the solvents evaporates and the filament forms. Able to work in wet spinning process, to produce viscose, acrylic fibres, dissolving polymer in solution and force under pressure through an opening into a liquid bath in which the polymer is insoluble.
- Tend twisting machines
Set up, operate, and maintain twisting machines to spin two or more fibres together into a yarn.
- Adjust filament tension
Adjust the tension of the filament to be wound. Make sure the filament is not so lax as to produce unevenness in the workpiece, or so tight as to introduces deformations in the filament or lower the filament ratio to unacceptably low levels.
