ABSTRACT:
A device for the automatic control of the weft yarn feed in air looms which includes a weft yarn feeder and sensors to sense the time required for each turn of the weft yarn leaving the feeder to unwind. The sensors generate a signal which is received by an analysis circuit associated with a programmable control circuit which controls the feeding of the weft yarn. The feeding of the yarn can be varied based on differences in the physical characteristics of the yarn which effect the operation of the loom.
