Abstract From the Canadian patent

The apparatus has two generally parallel transport means in the form of chains guided within tracks. Double armed levers are attached to the chains which carry clamping rollers, whose surfaces are of elastically yielding material. Folded printed matter is supplied to the clamping rollers of both transport means in a shingled stream. Every two printed items are folded within each other but displaced laterally by a distance A. The clamping rollers grasp the edges of the printed items and transport them. After grasping the printed matter, the transport means diverge whereby the, printed items which are folded within each other are also automatically drawn apart.
