Task statements

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