ABSTRACT:
A feeder system for serially feeding collapsed bag tubes including a first conveyor means for conveying a stack of tubes to a predetermined pickup location, second conveyor means spaced from the first conveyor means and feeder means disposed adjacent to the pickup location and between the first and second conveyor means for sequentially engaging the topmost tube in the stack and feeding it to the second conveyor means. The feeder means comprises a plurality of reciprocal picker arms and a pair of nip defining rotatable feeder elements disposed adjacent to the picker arms. The picker arms are adapted to serially transport the tubes from the top of the stack toward the nip defined by the rotatable feeder elements. The rotation of the rotatable feeder elements propels the tubes through the nip toward the second conveyor.
