Abstract (en)
In a transfer device R, which feeds a first web group W20 obtained by overlapping a plurality of webs and vertically folding them in a half width by a former F11 and a second web group W10 of a plurality of overlapped webs in the same width dimension as that of the first web group W20 vertically folded by the former F11 in mutual overlap between a cutting cylinder C1 and a folding cylinder C2, so as to form a newspaper signature, wherein at least one transfer roller R1, R2, R3, or R3' is provided for guiding the second web group W10 to a position at which it is overlapped on the first web group W20 and at least one out of the transfer rollers is rotationally driven, at least one of the transfer rollers to be driven is a roller having a step formed at a peripheral surface in a range in contact with the web while circumferential surfaces having different diameters in an axial direction are adjacent to each other, thus providing the transfer device for a folder unit capable of applying an appropriate tension to each of the webs constituting the web group, so as to prevent the web from being deviated or meandering.
