Monitoring systems can be distinguished according to whether they monitor

  • the machine,
  • the production, or
  • the quality.

With machine monitoring systems, sensors are provided at all essential points to ensure that the machines are stopped immediately if a sliver breaks or runs out, if a lap forms, and so on. This is most important, since considerable damage can otherwise be caused to the machine. Production monitors respond primarily to interruptions in operation of the machine; they calculate the efficiency of the machine and the quantity produced in total and per machine. For monitors of quality, three types were formerly in use, namely those with:

  • displays;
  • self-compensation; and
  • autoleveling.

The devices of the first group cannot replace an autoleveler, but they were valuable and very important aids to monitoring operation. Where these systems were used, the slivers delivered were continuously checked for hank consistency (and in some cases also for evenness over short lengths). If an unacceptable deviation from the set value arose, this was indicated and the machine usually stopped.
