Abstract: A plurality of aligned pairs of stacking blades are indexed downward past the output end of a lapped stream newspaper conveyor. The blades are pivotally mounted to respective sets of link chains and spring biased to a normal position. A latch member interferes with a pair of blades just above the input conveyor to restrain those blades against the spring bias and releases them coincident with the beginning of an indexing cycle to cleanly intercept the stream and index those blades to a stacking position. A subsequent indexing cycle moves those blades apart to drop the stack to a table which may be indexed in onehalf revolution intervals to permit a second stack to be dropped upon the first, forming a double batch stack with the folded edges on opposite sides. The table has high side walls and mechanically operated gates closing off the ends between the sidewalls to restrain the stack on the table during indexing. A gate actuating mechanism on the frame of the machine is spring biased to normally engage the gate linkage to cause the gates to be opened, but the mechanism is held retracted at all times except during the operation of a pusher mechanism which travels over the table to eject the stack.
