Abstract: A bobbin-handling system for a self-tending spinning frame is disclosed. Tenders move back and forth along spinning stations and stop to service the stations as required. For example, the tenders doff filled bobbins, and then donn and thread-up empty bobbins. A belt conveyor encircles the spinning frame and has upper runs for carrying empty bobbins to the tenders and lower runs for receiving filled bobbins from the tenders and discharging the filled bobbins from the system. Special bobbin guides are provided at corners where the conveyor belts cross each other. Empty bobbins are automatically spaced from each other as they are delivered to the conveyor and apparatus is provided for automatically maintaining adequate spacing of the bobbins after they are delivered to the conveyor.

Abstract: Bobbin handling apparatus in which bobbins are stored in random orientation in a hopper and are delivered by the apparatus in an oriented manner. The bobbins in the hopper are agitated by a member movable vertically through the hopper. This member has an upwardly open mouth and upon upward movement of the member the mouth receives small ends of a portion of the bobbins in the hopper with large ends of the bobbins resting on the member adjacent the mouth. A pusher is provided for moving the bobbins to one end of the mouth from which they are received between a pair of downwardly inclined rods rotated in opposite directions so as to lift the bobbins and permit them to move down the rods to an escapement. When a bobbin is required, the escapement opens to permit a bobbin to be discharged through a chute to a conveyor belt with the bobbins oriented on the belt with smaller ends leading.
