ABSTRACT:
An apparatus and method for forming a stream of shingled fanfold sheet device into a vertical stack comprises a first table having lengthwise belts which receive and push the shingled sheet against a stop, causing the sheet to form into a horizontal stack. The first table has powered transfer rollers positioned in the spaces between the belts. Upon command, the belts lower beneath the table surface, so that the transfer rollers engage the stack and move it sideways onto an adjacent pivotable second table. The second table pivots about an axis transverse to the lengths of the first table and second table. Preferably, the second table has a stop at one end and a detachable pallet at the other end. When the second table is rotated, the stack is made vertical so it rests on the pallet. The pallet with stack are then withdrawn from engagement with the second table for transport elsewhere. A third conveyor belt table may be positioned between the source device and the first table. Preferably, the pallet and stop may be attached interchangeably to opposing ends of the tilting table, to enable the rotational direction of the table to be reversed, and as a result, the top to bottom sequence of fanfold pages within the vertical stack is reversed.
