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.

The following job titles also refer to twisting machine operator:

No formal educational credential is generally required to work as twisting machine operator.

ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:

• the nature of the work performed in an occupation in relation to the characteristic tasks and duties
• the level of formal education required for competent performance of the tasks and duties involved and
• the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.

Twisting machine operator is a Skill level 2 occupation.

These occupations, although different, require a lot of knowledge and skills similar to twisting machine operator.

man-made fiber spinner
spinning textile technician
winding machine operator
spinning machine operator
yarn spinner

These occupations require some skills and knowledge of twisting machine operator. They also require other skills and knowledge, but at a higher ISCO skill level, meaning these occupations are accessible from a position of twisting machine operator with a significant experience and/or extensive training.

leather laboratory technician
textile process controller
textile quality technician
colour sampling technician
civil registrar

This knowledge should be acquired through learning to fulfill the role of twisting machine operator.

• Types of textile fibres: The variety of textile fibres both natural such as wool and hemp and man-made or synthetic fibers.
• Staple spinning machine technology: Technologies, operations, monitoring and maintenance of machines during the yarn spinning process.

These skills are necessary for the role of twisting machine operator.

• Prepare raw materials for man-made fibres manufacturing: Settle the supply of raw materials that need to go into the processing phase such as spinning, in order to prepare the fibres for manufacturing purposes.
• Prepare raw materials: Prepare and measure the basic materials that are needed to produce goods and finished products.
• 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.
• Maintain equipment: Regularly inspect and perform all required activities to maintain the equipment in functional order prior or after its use.
• Convert textile fibres into sliver: Convert textile fibres into drafting sliver by working in the fibre opening, carding and drafting process.
• 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.
• Tend twisting machines: Set up, operate, and maintain twisting machines to spin two or more fibres together into a yarn.
• 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.
• Cut filament: After the filament workpiece has been wound, cut the filament to release the workpiece.

This knowledge is sometimes, but not always, required for the role of twisting machine operator. However, mastering this knowledge allows you to have more opportunities for career development.

• Rope manipulation: Rope manipulation which relates to knotting and splicing.
• Functionalities of machinery: The machinery and equipment used and, in particular, the characteristics regarding functioning and calibration to ensure compliance with quality and product specifications, as well as the operator’s safety.

These skills and competences are sometimes, but not always, required for the role of twisting machine operator. However, mastering these skills and competences allows you to have more opportunities for career development.

• Organise wires: Apply wire markers and cable labels to identify and organise the wire. Use tie-wrap or cable lace to keep the wires together.
• Remove defective products: Remove defective materials from the production line.
• Measure yarn count: Be able to measure yarn length and mass to assess fineness of roving, sliver and yarn in different measuring systems.Also able to convert into the various numbering system such as tex, Nm, Ne, denier, etc.
• Adapt to changing situations: Change approach to situations based on unexpected and sudden changes in people’s needs and mood or in trends; shift strategies, improvise and naturally adapt to those circumstances.
• Use communication techniques: Apply techniques of communication which allow interlocutors to better understand each other and communicate accurately in the transmission of messages.
• Manufacture non-woven filament products: Perform the operation, monitoring and maintenance of machines and processes to manufacture nonwoven filament products, keeping efficiency and productivity at high levels.
• Process man-made fibres: Converting synthetic granule into man-made-fibres such as filament yarns or staple fibre yarns.
• Covert slivers into thread: Convert slivers into yarns or threads by combing processes converting drafting card sliver to combed sliver. Form short fibre to yarn using yarn and thread processing technologies, mostly ring spinning or open-end spinning (rotor spinning) or alternative spinning techniques. Work in the drafting or drawing process converting sliver into roving and converting roving into yarn, through further drafting and twisting processes. Work on winding machines to reel the yarn from bobbins onto spools or cones.
• Follow work procedures: Adhere to procedures at work in a structured and systematic manner.
• Report defective manufacturing materials: Maintain required company records and forms in order to report any defective materials or questionable conditions of manufacturing machinery and equipment.
• Perform sample testing: Examine and perform tests on prepared samples; avoid any possibility of accidental or deliberate contamination during the testing phase. Operate sampling equipment in line with design parameters.
• Work as a team: Cooperate with colleagues in order to ensure that operations run effectively.
• Ensure equipment maintenance: Ensure that the equipment required for operations is regularly checked for faults, that routine maintenance tasks are performed, and that repairs are scheduled and performed in the case of damage or flaws.
• Manufacture texturised filament yarns: Perform the operation, monitoring and maintenance of machines and processes to manufacture texturised filament yarns.
• Execute working instructions: Understand, interpret and properly apply work instructions regarding different tasks in the workplace.
• Identify with the company’s goals: Act for the benefit of the company and for the achievement of its targets.
