ABSTRACT:
This invention relates to a method and apparatus for processing yarn defect signals of a plurality of yarns on the on-line base.
For this purpose and in the case of the signal processing apparatus according to this invention a large number of yarn defect signals are processed through a scanning device for signal sampling, means is provided for placing possible drop-out signals into respective provisional memories, and preferably in the form of a binary "1" from a binary "0" and for reading out the contents from the memories at the beginning the next succeeding sampling period and for further processing these read-out yarn defects signals, together with regular yarn defects signals under processing through regular samplings.
