Initially only the flyers and the spindles of the flyer are driven. The flyers and the spindles are either immediately advanced in a forward direction or are initially driven backwards and after the lapse of a predetermined time period, brought to standstill and then driven forwardly, whereby the standstill of the flyers and the spindles coincide in time or are offset in time. After the start of the forward drive of the flyers and the spindles, the time-delayed drafting frame is set into operation.
