Extruding and Forming Machine Setters, Operators, and Tenders, Synthetic and Glass Fibers

Tasks


Core Tasks Include:

  • Remove excess, entangled, or completed filaments from machines, using hand tools.
  • Set up, operate, or tend machines that extrude and form filaments from synthetic materials such as rayon, fiberglass, or liquid polymers.
  • Load materials into extruding and forming machines, using hand tools, and adjust feed mechanisms to set feed rates.
  • Start metering pumps and observe operation of machines and equipment to ensure continuous flow of filaments extruded through spinnerettes and to detect processing defects.
  • Move controls to activate and adjust extruding and forming machines.
  • Record details of machine malfunctions.
  • Notify other workers of defects, and direct them to adjust extruding and forming machines.
  • Press buttons to stop machines when processes are complete or when malfunctions are detected.
  • Observe flow of finish across finish rollers, and turn valves to adjust flow to specifications.
  • Observe machine operations, control boards, and gauges to detect malfunctions such as clogged bushings and defective binder applicators.
  • Open cabinet doors to cut multifilament threadlines away from guides, using scissors.
  • Press metering-pump buttons and turn valves to stop flow of polymers.
  • Remove polymer deposits from spinnerettes and equipment, using silicone spray, brass chisels, and bronze-wool pads.
  • Clean and maintain extruding and forming machines, using hand tools.

Supplemental Tasks Include:

  • Pass sliver strands through openings in floors to workers on floors below who wind slivers onto tubes.
  • Turn petcocks to adjust the flow of binding fluid to sleeves.
  • Turn rheostats to obtain specified temperatures in electric furnaces where glass is melted.
  • Record operational data on tags, and attach tags to machines.
  • Lower pans inside cabinets to catch molten filaments until flow of polymer through packs has stopped.
  • Pull extruded fiberglass filaments over sleeves where binding solution is applied, then into grooves of graphite shoes that bind filaments into single strands of sliver.
  • Wipe finish rollers with cloths and wash finish trays with water when necessary.
