ABSTRACT:
An apparatus for providing a constant supply of circulating textile bobbin tubes from a delivery conveyor of a textile winding machine to a return conveyor of a textile spinning machine. A reserve magazine containing textile bobbin tubes is combined with an accumulating magazine through which tubes are received from a winder and discharged for feeding to a spinning machine, with the reserve magazine discharging tubes to a transfer conveyor whenever there is an absence of supply of tubes from the accumulating magazine. An overflow collector collects tubes received from the winder in excess of the number necessary to maintain the accumulating magazine full, with the overflow of tubes being transferred manually or automatically to the reserve magazine. Discharge from the magazines is controlled by a sensor that senses the supply of tubes to the spinning machine and by sensors that sense the advance of the transfer conveyor and the presence or absence of a tube on the transfer conveyor adjacent the reserve magazine.
