  • Apparatus and method for changing and winding bobbins involving the correction of movement sequences in a moving element
    Patent number: 5676323
    Abstract: A textile machine with an apparatus for recognizing and correcting deviations of sequences of movements of an element (31) driven by a driving element (33). A device (51) acquires the arrival time (t.sub.4) of the driven element (31) and corrects the start time (t.sub.1) of the driving element (33) within a predefined time window (t.sub.1u -t.sub.1o) until the arrival time (t.sub.4) of the driven element (31) lies within a predefined time window (t.sub.2u -t.sub.2o) again.
