Abstract

It is an object to provide a web offset press in which the possibility of causing product quality problems can be prevented at least when a web is folded in two or is overlaid in two layers by a former board. It includes a former board; a folding processing device (F) that processes a half-width web that is folded in two or is overlaid in two layers by the former board into a signature; and a position-adjustment control device that adjusts the position of the former board in the widthwise direction of the half-width web so as to match the widthwise central position (WM) of the half-width web and the widthwise processing central position (MM) of the folding processing device (F); wherein the position-adjustment control unit stores a predetermined widthwise position of the former board according to the form of the half-width web and moves the former board to the predetermined widthwise position.
