Textile Machinery and Maintenance

Machine anatomy

Know the main components of key machines: card (cylinder, flats, doffer), draw frame (drafting rollers, autoleveller), ring frame (drafting system, spindle, traveller, ring), loom (heddle, reed, shuttle or rapier, sley) and knitting machine (needle, sinker, cam). Understand the function of each part and its adjustment.

Maintenance strategy

Preventive, predictive and breakdown maintenance differ in cost and downtime. Lubrication schedules, vibration analysis and thermography support predictive maintenance. Spare parts management and MTBF/MTTR are examinable concepts.

Traps

  • Confusing traveller with spindle; the traveller runs on the ring.
  • Mixing preventive (scheduled) with predictive (condition-based) maintenance.
  • Ignoring the effect of machine setting on yarn quality.

Worked example

If a machine runs 500 hours and fails 4 times, MTBF = 500/4 = 125 hours. If total repair time is 20 hours, MTTR = 5 hours, and availability = MTBF/(MTBF + MTTR) = 125/130 ≈ 96.2%.
