Reducing Second Quality From Machine Faults
Most second quality is not a knitting error, it is a fault the machine ran on with. Detection and lint control are where the fabric is saved.
The Working Method
- Restore stop motion coverageEvery feeder should stop the machine on a broken or slack end. Detectors that were bypassed during an old repair are common and easy to miss.
- Fit or repair needle detectionA broken needle puts a running line down the whole roll. A working detector stops the machine at the fault instead.
- Control lint at sourceFly settles in the tricks and ends up in the fabric. Dedusters and fan cleaners remove it before it packs.
- Keep the needle bed lubricatedDry running wears hooks and latches, and worn needles drop stitches. Metered lubrication is more consistent than hand oiling.
- Change parts as setsA machine running mixed wear produces fabric with mixed loop length. Full sets on a planned cycle cost less than the downgrade.
Frequently Asked Questions
Where should we start if the budget is limited?
Detection first. A stop motion or needle detector that works turns a whole roll of second quality into a short stop.
How do we know detection is actually working?
Test it deliberately. Break an end at a feeder and confirm the machine stops. Bypassed circuits only show up when they are tested.
