Set up, operate, or tend machines that wind or twist textiles; or draw out and combine sliver, such as wool, hemp, or synthetic fibers.

Measure bobbins periodically, using gauges; and turn screws to adjust tension if bobbins are not of specified size. Observe bobbins as they are winding; and cut threads to remove loaded bobbins, using knives. Observe operations to detect defects, malfunctions, or supply shortages. Operate machines for test runs to verify adjustments and to obtain product samples. Place bobbins on spindles and insert spindles into bobbin-winding machines. Remove spindles from machines and bobbins from spindles. Replace depleted supply packages with full packages. Start machines, monitor operation, and make adjustments as needed. Stop machines when specified amount of products has been produced. Study guides, samples, charts, and specification sheets, or confer with supervisors or engineering staff to determine setup requirements. Tend machines that wind wire onto bobbins, preparatory to formation of wire netting used in reinforcing sheet glass. Tend machines that twist together two or more strands of yarn or insert additional twists into single strands of yarn to increase strength, smoothness, and/or uniformity of yarn. Tend machines with multiple winding units that wind thread onto shuttle bobbins for use on sewing machines or other kinds of bobbins for sole-stitching, knitting, or weaving machinery. Tend spinning frames that draw out and twist roving or sliver into yarn. Thread yarn, thread, and/or fabric through guides, needles, and rollers of machines. Unwind lengths of yarn, thread, or twine from spools and wind onto bobbins. Clean, oil, and lubricate machines, using air hoses, cleaning solutions, rags, oilcans, and grease guns. Inspect machinery to determine whether repairs are needed. Notify supervisors or mechanics of equipment malfunctions. Record production data such as numbers and types of bobbins wound. Repair or replace worn or defective parts or components, using hand tools. Install, level, and align machine components such as gears, chains, guides, dies, cutters, and/or needles to set up machinery for operation. Adjust machine settings such as speed or tension to produce products that meet specifications. Inspect products to verify that they meet specifications and to determine whether machine adjustment is needed.

Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance.

Operation and Control -- Controlling operations of equipment or systems. Quality Control Analysis -- Conducting tests and inspections of products, services, or processes to evaluate quality or performance. Repairing -- Repairing machines or systems using the needed tools. Operation Monitoring -- Watching gauges, dials, or other indicators to make sure a machine is working properly. Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed. Installation -- Installing equipment, machines, wiring, or programs to meet specifications. Troubleshooting -- Determining causes of operating errors and deciding what to do about it. Reading Comprehension -- Understanding written sentences and paragraphs in work related documents. Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Technology Design -- Generating or adapting equipment and technology to serve user needs.

Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations). Arm-Hand Steadiness -- The ability to keep your hand and arm steady while moving your arm or while holding your arm and hand in one position. Written Comprehension -- The ability to read and understand information and ideas presented in writing. Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects. Problem Sensitivity -- The ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem. Finger Dexterity -- The ability to make precisely coordinated movements of the fingers of one or both hands to grasp, manipulate, or assemble very small objects. Visualization -- The ability to imagine how something will look after it is moved around or when its parts are moved or rearranged. Wrist-Finger Speed -- The ability to make fast, simple, repeated movements of the fingers, hands, and wrists. Oral Comprehension -- The ability to listen to and understand information and ideas presented through spoken words and sentences.

Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events. Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials. Evaluating Information to Determine Compliance with Standards -- Using relevant information and individual judgment to determine whether events or processes comply with laws, regulations, or standards.
