Abstract
A method and apparatus operable on a jet dyeing or finishing machine having a treatment chamber, a lifter reel, and a jet nozzle for movement of a fabric rope through the chamber for wet treatment thereof. Such an apparatus includes a direct current motor for driving the lifter reel, a mechanism for periodically deactivating the lifter reel drive, a sensing component for sensing the electromotive force (EMF) generated by the direct current lifter reel motor during periods of deactivation, and appropriate circuitry for comparing the sensed EMF value with a predetermined threshold value and signaling an operator in the event that the sensed EMF value is below the predetermined threshold value. A low EMF value is interpreted as an indication that the fabric rope is stopped or moving slowly over the lifter reel, with the lifter reel drive motor correspondingly rotating at a relatively lower rotational velocity, and the assumption is made that the slow rate of travel of the fabric rope is caused by tangling or other disruptions.
