Abstract: The method and the apparatus of the invention serve to shift at least some sheets of successive stacks of overlapping sheets so that the originally straight holes which are provided along one marginal portion of each stack are converted into arcuate passages adapted to more readily receive the convolutions of spirals serving to pivotably couple the sheets of the stacks to each other. This is accomplished by inserting into one or both ends of some or all of the holes a discrete pin-shaped displacing member which is thereupon pivoted to thus shift at least some of the sheets relative to the neighboring sheets. In order to speed up the shifting of sheets, the displacing member or members is or are pivoted during withdrawal from the respective hole or holes to move its or their tips along arcuate paths at least approximating the curvatures of the convolutions which are to be introduced into the thus converted holes.

Abstract: Several printing units are arranged in a row for printing on as many separate webs traveling in centerline alignment and in phase with one another. At least one preselected web, on issuing from one printing unit, is directed over an angled guide rod thereby to be turned 90 degrees out of phase with the other, unselected webs. Subsequently traveling over a triangular shaped former, the preselected web is folded along a centerline thereof, back into phase with the unselected webs. The preselected web, already formed, and the unselected ones, yet unfolded, are then all superposed one upon another, with the fold of the preselected web in register with the aligned centerline of the unselected webs. The superposed webs are then folded by another former along the aligned centerline of the unselected webs. Subsequently fed into a cutting and folding device, the webs are cut and folded transversely into individual multiple-page signatures each having one center spread in addition to the usual inmost center spread.
