ABSTRACT:
A packet feeder system having a track extending between a packet feeder and the packet receiving end of a magazine includes a discharge end of the track that is adjustably positionable relative to the receiving end of the magazine. Appropriate sensors are provided for detecting the position of the uppermost packet within the magazine relative to the discharge end of the track and a suitable control unit is responsive to the sensing device for controlling the adjustable position of the discharge end of the track. In addition, the track is provided with sequenced gating for controlling movement of the packets along the track. The gating includes a plurality of barriers spaced along the length of the track by a distance slightly greater than the length of the packets. The control unit is effective to sequentially move the barriers into and out of a packet restraining position in a sequence whereby adjacent barriers are prevented from being out of their restraining positions simultaneously.
