A dyeing machine may need the following on/off operations performed in a wide variety of timed sequences— water inlet, drain valve, steam, pump motor, dye feed, salt feed, finish feed. COPE provides an automatic control for all these, as well as for dyebath temperature and liquor level. Good reproducibility of shade has been obtained on repeat dyeings using this automatic control.
