Problems exist such as the presence of a narrow gap when the vicinity of a spliced joint of paper webs is passed between an outer surface of a roller and an outer surface of a folding cylinder. Paper blockages due to increased thickness are therefore likely to arise, making it easy for the paper web to become torn. This in turn damages the paper, and machine stoppages are also increased. <??>A folder FD of this invention is provided with a rotating roller 1 for wrapping paper webs W fed from upstream around a side facing a folding cylinder 3 to guide the webs to the folding cylinder 3 outer surface, provided close to a position where a plurality of pins 31 provided at appropriate places in an axial direction of the folding cylinder 3 pierce fed paper webs W, further upstream than a paper web W cutting position between the folding cylinder 3 and a cutting cylinder 4, parallel to the axis of the folding cylinder 3, wherein an outer part of the roller 1 is formed from a cushion member 11 capable of absorbing variations in a thickness direction of paper webs W fed from an upstream side. <IMAGE> |
