Abstract
Apparatus is provided for taking a stack of flat articles such as folded newspapers, and delivering them successively to a conveyor in an overlapped or shingled arrangement to move to a processing station for labeling or addressing or for opening them to receive inserts. A rectangular hopper or gate is located over a traveling belt means to hold a stack of such flat articles with its converging angle pointing downstream. Each bottom article is gripped by the belt means, which is vacuumized in the area under the stack, and is pulled under the gate and downstream. When a given article is only partially through the gate, the succeeding article is gripped primarily by its side portions and pulled under the gate in overlapping or shingled relation with the preceding one, each article being arranged with its side edges at a substantial angle to the direction of travel. A shield underlies the rear portion of the stack to prevent gripping the rearmost portions of the articles until they are moving with the speed of the belt to prevent distortion or damage.
