Abstract: A method and apparatus for counting yarn splicing operations for each of the spindles in an automatic winding machine provided with a plurality of winding spindles and an automatic knotting machine and in which relative motion of said spindles and said knotting machine causes the knotting machine and successive spindles to be adjacent each other for carrying out a yarn splicing operation when necessary. A pulse signal is generated each time the knotting machine and a spindle are adjacent each other during the relative motion of the knotting machine and the spindles, the pulse being of relatively short duration when the knotting machine is adjacent a spindle for a time insufficient to carry out a splicing operation. The apparatus discriminates between the long and short duration pulses for each spindle, and the long duration pulses for each spindle are counted as an indication of the occurrances of a splicing operation for that spindle.

Abstract: A method and apparatus for counting yarn splicing operations due to normal and abnormal reasons for each of the spindles in an automatic winding machine provided with a plurality of winding spindles each having associated therewith a slub catcher and bobbin replacing means, and an automatic knotting machine circulating past the spindles for carrying out yarn splicing at each of said spindles when necessary. A yarn splicing operation at each spindle is detected by a yarn splicing detecting means including a reed switch associated with each spindle for producing a yarn splicing detecting signal when closed for longer than a predetermined time, and a magnet secured to the automatic knotting machine operates the respective reed switches.
