  • a newspaper signature is normally formed by a web-fed press, as follows: a longitudinal dimension of a web is determined in accordance with a predetermined cut dimension in a folder unit; a plurality of printed webs in a two-page width are overlapped one on another, to be fed through a former in the folder unit; and the webs are vertically folded in a half width in parallel to a traveling direction by the former, thus to obtain a web group having a one-page width, that is, a width of a folding signature (hereinafter referred to a folding signature width), with which the webs are discharged onto a conveyor in the folder unit, described later.
  • a folding signature width a folding signature width
  • the web group is guided to a cut position located between a cutting cylinder and a folding cylinder, to be cut in the predetermined cut dimension by a cutting blade fixed to the cutting cylinder perpendicularly to the traveling direction of the webs; is laterally folded by the folding cylinder and a folding roller; thus obtaining a quarto newspaper signature (hereinafter referred to a signature A) of the web group to be discharged onto the conveyor via a delivery fan.
  • a signature A a quarto newspaper signature
  • a plurality of printed webs having the folding signature width in the state in which a longitudinal dimension of a web is determined in accordance with a predetermined cut dimension in a folder unit are overlapped one on another, thereby obtaining a web group which is then guided to a cut position located between a cutting cylinder and a folding cylinder, to be cut in the predetermined cut dimension by a cutting blade fixed to the cutting cylinder perpendicularly to the traveling direction of the webs; is laterally folded by the folding cylinder and a folding roller; thus obtaining a another folio newspaper signature (hereinafter referred to a signature B) of the web group to be discharged onto the conveyor via a delivery fan.
  • a signature B another folio newspaper signature
  • a combined web group (hereinafter referred to as a web group E) should be first obtained by overlapping a web group having a folding signature width which consists of the folding signature A (hereinafter referred to as a web group A) obtained by vertically folding, in the half width, the plurality of overlapped webs having the two-page width by the former and another web group consisting of the plurality of overlapped webs having folding signature widths which consist of the folding signature B (hereinafter referred to as a web group B) in the state in which the web groups are aligned at both side edges thereof with each other; and then, the web group E is guided to a cut position located between a cutting cylinder and a folding cylinder, to be cut in the predetermined cut dimension by a cutting blade fixed to the cutting cylinder perpendicularly to the traveling direction and is laterally folded by the folding cylinder; thus forming a newspaper signature (hereinafter referred to as a folding
  • the traveling direction of the transfer device provided in the folder unit is changed in contact of the web group at a roll angle with one or more transfer rollers rotatably supported. Therefore, the tension of the web group to be transferred is decreased due to extension generated in the traveling direction or the rotational resistance of the transfer roller during the traveling on the web paths in the transfer device, so that the web meanders caused by its movement in the width direction during its traveling, thereby raising a problem of degradation of the quality of the folding signature.
  • Patent Document 1 Japanese Utility Model Application Laid-open No. Sho 62-53279 discloses a technique in a transfer device for a folder unit.
  • a transfer device disclosed in Patent Document 1 is provided with a rotary drive device in a transfer roller, so as to apply an appropriate tension to a web.
  • a transfer path in a transfer device recently tends to become longer for various reasons in, for example, a folder unit provided with a balloon former disposed above a general former or a folder unit provided with a former elongated in a traveling direction of a web while taking a greater inclination angle between the surface of the former and a horizontal plane.
  • tension is conspicuously decreased due to extension generated in the traveling direction, and further, an air layer is frequently taken in between the webs.
  • the web group B in which the plurality of webs having the folding signature width are overlapped one on another, the radially inside web guided in contact with the periphery of the transfer roller and the radially outside web guided from the periphery of the transfer roller via the plurality of webs are independent of each other, and therefore, neither of the side edges in the width direction are closed. Consequently, the air layer is liable to be markedly taken in between the webs during the transferring, that is, while the web group B travels between a nipping roller and the transfer roller or between the transfer rollers. Even if the web group B is brought into contact with the transfer roller at a roll angle, the air layer taken in between the webs cannot be completely discharged only from both of the side edges of the web group B.
  • an object of the present invention is to provide a transfer device for a folder unit capable of applying an appropriate tension to each of webs constituting a web group, so as to prevent the web from being deviated or meandering.
  • a transfer device for a folder unit which feeds a first web group obtained by overlapping a plurality of webs and vertically folding them in a half width by a former and a second web group of a plurality of overlapped webs in the same width dimension as that of the first web group vertically folded by the former in mutual overlap between a cutting cylinder and a folding cylinder, so as to form a newspaper signature
  • at least one transfer roller is provided for guiding the second web group to a position at which it is overlapped on the first web group and at least one out of the transfer rollers is rotationally driven, wherein 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.
  • the transfer roller is the roller having the step formed in the range with which the web is brought into contact adjacently to the circumferential surface having the different diameters in the axial direction, so that the web path detours within the range in contact with the small-diameter portions with respect to the range in contact with the large-diameter portions of the transfer roller in the web group in contact with the transfer roller at the roll angle, and accordingly, each of the webs is firmly pressed against the surface of the transfer roller.
  • each of the webs is weakly pressed against the surface of the transfer roller in the range in contact with the small-diameter portions, and therefore, an air layer taken in between the webs is pushed out from between the webs in contact with the large-diameter portions firmly pressed against the transfer roller toward the range in contact with the small-diameter portions at which the pressing force is weak, thereby dissipating the air layer taken in between the webs in contact with the large-diameter portions.
  • the webs are brought into contact with each other at the large-diameter portions on the transfer roller, thus transmitting the power generated by the frictional force.
  • the two transfer rollers to be driven should approach each other, at least either one of the transfer rollers should be 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, and further, at least one arrangement should be provided in such a manner that the transfer roller is brought into contact with one side and the other side of the second web group with certain central angle.
  • one of the transfer rollers is disposed in the vicinity of the other transfer roller, both of the transfer rollers being brought into contact with the different sides of the second web group at the roll angle, so that the power can be sufficiently transmitted, from the other transfer roller, even to the web remoter from the surface of one of the transfer rollers, thus applying the appropriate tension to the entire web constituting the web group. Consequently, it is possible to further enhance the effect of preventing the web from being deviated or meandering.
  • large-diameter portions should be arranged at the circumferential surface having the different diameters substantially symmetrically with respect to a center in a width direction of the web.
  • a ratio of a large-diameter portion to a small-diameter portion in an axial direction range at the circumferential surface having the different diameters should be equal to or smaller than the small-diameter portion.
  • a circumferential surface of a large-diameter portion at the circumferential surface having the different diameters should be subjected to surface treatment for increasing a friction coefficient.
  • a traveling tension to be applied to the web group in the width direction can be balanced, thus eliminating any occurrence of deviation.

  • the four webs are overlapped one on another by the balloon former F21 and a pair of forming rollers U21 in a state in which both widthwise ends are aligned with each other, thereby constituting the second web group W10 without any former-folded portion.
  • the second web group W10 is fed downstream while both their side being held between driven nipping rollers M1a and M1b by appropriate force.
  • the second web group W10 is brought, at a roll angle, into contact with the nipping roller M1a and a transfer roller R1, which is disposed under the nipping rollers M1a and M1b and on a frame side nearer the nipping roller M1a (hereinafter referred to as an operation side), and thus, the traveling position of the second web group W10 is moved onto the operation side down to a position at which the second web group W10 cannot interfere with the lower former F11.

  • the second web group W10 and the first web group W20 are overlapped one on another while being held between the second nipping roller N2a and the other second nipping roller N2b by appropriate force, thereby constituting a combined web group which is then fed out.
  • the combined web group is further fed out by the third nipping rollers N3a and N3b, to travel between the cutting cylinder C1 and the folding cylinder C2.
  • the first web group W20 is wound around the peripheral surface of the folding cylinder C2 while the overlapped second web group W10 is oriented inward.
