ABSTRACT:
Apparatus for transporting folded sheets has one or two pairs of chain conveyors whose horizontal upper reaches define two spaced-apart portions of a first path for the transport of successive folded sheets of a series of sheets in such a way that the sheets ride on the pairs of conveyors in inverted positions (with the backs on top). An additional chain conveyor has a horizontal upper run defining a second horizontal path between the first and second portions of the first path to transfer the sheets from the first to the second portion of the first pair. The additional chain conveyor advances successive sheets along a stationary ramp which pivots the panels of the sheets apart so that the thus exposed inner sides of the panels are accessible for the application of printed information, labels or the like. The speed of the additional conveyor can slightly exceed the speed of the other chain conveyor or conveyors.
