Abstract: Strand handling apparatus including a system for controlling a cycling carriage which scans and services bobbin winding stations on a spinning machine, or the like. The control system provides a signal indicating when a station being scanned is operational and service signals indicating when the station requires servicing. Upon receipt of both the operational and servicing signals the control system initiates a work cycle of the carriage to service the station. The service signals include both a full bobbin signal and a strand interruption signal. If there are more than a predetermined number of interruption signals during a cycle, the control system does not cause servicing of the stations responsive to this signal. If a roll-wrap occurs on a drafting roll of a station the strand is broken and does not enter the drafting rolls and the operational signal is not provided at this station so that the carriage bypasses the station until it is again placed in operational condition by an attendant. Upon starting-up with fresh bobbins at all of the stations, most of the stations would be ready to have their full bobbins doffed at about the same time, and the carriage would be overworked. Therefore, at startup the control system provides for doffing the stations in succession at timed intervals, and in conjunction with the operational and the servicing signals, to randomize the future doffing cycle of the stations.
