Definitions

  • Folding rollers comprising front and rear axial sections are known in the state of the art.
  • the rear axial portion extends at a rear portion of a signature to be folded, while the forward axial portion extends at a leading edge of a signature to be folded.
  • the rear axial section comprises a recess adapted to release the upper part of the signature to be folded to prevent creases of the downstream part of the folded notebook.
  • the known folding rolls are adapted to grip the current part of the notebook at its front edge to fold the notebook.
  • the document EP 0 855 356 A2 discloses two folding rolls for a folder. These folding rollers consist, from the outside towards the inside, of two traction rings followed by an intermediate ring and a main body. The edges of the roll are provided with clearances releasing the signature during folding and thus avoiding creases in the signature.
  • the central body has two grooves for guiding routing cords.
  • the document EP 0 366 611 A2 describes two folding rolls. These folding rolls are divided, according to their circumference, into three zones. An area corresponds to the folding zone with a cylindrical surface. This folding zone extends over approximately one third of the length of the signature. This zone is only interrupted by grooves used to guide routing cords. The second zone corresponds to the second third of the signature and has a central clearance surrounded to the right and left of two surfaces. The edges of the signature apply to both surfaces. The last zone corresponds to the free third of the signature and is formed by a clearance that extends over the entire width of the guide rollers.
  • the document US 4, 781, 667 shows two variants of folding rollers.
  • the first variant has a clearance that extends over the entire width of the roll.
  • the second variant corresponds to a roll with two peripheral clearances. However, the clearances have an angular extent of the order of 90 °. Also, this document relates to a second fold and not to the square fold.
  • the object of the invention is to improve the quality of folding, especially at high folding speeds.
  • the subject of the invention is a roll according to the features of claim 1.
  • Folder 2 is a square bender of a rotary press, including an offset press.
  • the folder 2 comprises a folding table 4, a folding blade 6, two folding rollers 8 and 10, as well as routing cords 12.
  • the folder 2 is adapted to fold a signature S conveyed by the routing cords 12 on the folding table.
  • the folding table 4 extends according to a table plane P-P, and defines a folding slot 14.
  • the folding blade 6 is disposed above the folding table 4 and is adapted to push the central portion 24 of a signature S through the folding slot 14.
  • the folding rollers 8, 10 each extend along a central axis XX and define a folding gap 16 between them.
  • the folding roller 8 is driven in a first direction of rotation R1 and the folding roller 10 is driven in a second direction of rotation R2 opposite the first direction of rotation R1.
  • the folder 2 comprises a stop 18 adapted to stop the signature S before folding.
  • the routing cords 12 are driven in a driving direction E or conveying direction extending from an entrance of the folder 2 to the stop 18.
  • Each signature S delimits a front edge 20 directed downstream of the driving direction E and a rear edge 22 directed upstream of the driving direction E.
  • Each signature S also having a central portion 24 which is folded by the blade 6 and the folding rollers 8 and 10.
  • Each signature also has two lateral edges 26 extending parallel to the drive direction E.
  • the signature S has a single flat sheet.
  • the signature S comprises at least one folded sheet whose fold forms the front edge 20.
  • the folding roll 8 being symmetrical (see figure 6 ) with respect to a blade plane in which the folding blade 6 extends.
  • the folding roll 8 comprises a first axial section 30, a second axial section 32, a third axial section 34 and a fourth axial section 36.
  • the first axial section 30 comprises a first folding surface 40 of the signature S to be folded.
  • This fold surface 40 is a circular cylinder surface with a circular section around the central axis X-X.
  • the first axial portion 30 further comprises an auxiliary clearance 42 which is radially recessed with respect to the first folding surface 40.
  • This auxiliary clearance 42 comprises plane facets.
  • the first axial portion 30 extends during folding at the rear edge 22 of the signature S.
  • the junction between the first folding surface 40 and the auxiliary clearance 42 forms a first joining edge A located at the downstream end of the auxiliary clearance 42, viewed according to the first direction of rotation R1.
  • the auxiliary clearance 42 extends around the central axis X-X over an angular range between 120 and 160 °, and preferably between 140 and 150 °.
  • the roller 8 is driven in such a way that the first folding surface 40 grips the central portion 24 when the folding blade 6 pushes the signature S
  • the first two folding surfaces 40 of the folding rollers 8, 10 grip the central portion 24 of the signature S.
  • the second axial portion 32 extends axially so as to overlap the front edge 20 during folding during operation of the folder.
  • the second axial portion 32 and therefore the auxiliary clearance 42, axially overlaps the stop 18.
  • the second axial portion 32 has a main recess 44 which is radially recessed with respect to the folding surface 40 of the first axial section 30.
  • the second axial portion 32 further comprises a second folding surface 46, which is a partial cylinder surface with circular section about the axis XX.
  • the second folding surface 46 is radially aligned with the first folding surface 40.
  • the main clearance 44 extends around the central X-X axis over an angular range preferably between 320 and 325 °. In general, it may be greater than 270 °, in particular greater than one of the ranges 300 °, 310 ° and 320 °, and this angular range is at most 325 °.
  • the junction between the second folding surface 46 and the main clearance 44 forms a second joining edge B located at the downstream end of the main clearance 44, seen in the first direction of rotation R1.
  • the first joining edge A and the second joining edge B are circumferentially aligned.
  • the junction between the second folding surface 46 and the main clearance 44 forms a third joining edge C located at the upstream end of the main clearance 44 seen in the first direction of rotation R1.
  • This third joining edge C is circumferentially overlapped by the folding surface 40.
  • the angular range of the auxiliary clearance 42 completely overlaps the angular range of the main clearance 44 in the circumferential direction around the central axis X-X.
  • the folding surfaces 40 and 46 are axially aligned.
  • the main clearance 44 and the auxiliary clearance 42 thus extend over different angular ranges around the central axis X-X.
  • the third axial portion 34 extends axially between the first axial section 30 and the second axial section 32.
  • the third axial section 34 is provided with a third folding surface 48 all around the central axis XX.
  • the third folding surface 48 thus has a cylindrical shape with a complete circular section around the central axis.
  • the third folding surface 48 is radially aligned with the first folding surface 40. This third axial section is therefore adapted to grip the signature S over its entire width between its central portion 24 and its lateral edges 26.
  • the third axial portion 34 is further provided with two grooves 50, 52 all around.
  • the folder 2 also comprises strippers 58 which engage in the grooves 50, 52 and which are adapted to guide the folded signature and to remove it from the folding rollers 8, 10.
  • the fourth axial portion 36 has a cylindrical surface with a circular section centered on the X-X axis.
  • the second axial section 32 is arranged axially between the fourth axial section 36 and the first axial section 30 or the third axial section 34.
  • the folding roll 8 further comprises two journals 60 disposed on each side of the roll.
  • Folder 2 operates in the following manner.
  • the signatures S are transported by the routing cords 12 to the stop 18.
  • the folding blade 6 pushes the central portion 24 through the folding slot 14 and the central portion 24 is grasped by the first folding surface 40 as well as by the third folding surface 48
  • the portion of the central portion 24 which overlaps the second axial portion 32, as well as the portion of the front edge 20 adjacent to the central portion are first grasped by the second folding surface 46.
  • the signature S is routed through the folding gap 16 through the first, second and third folding surfaces until the main clearance 44 releases the leading edge portion 20 of the signature at a location at distance of the fold formed in the central portion 24.
  • the first folding surface 40 as well as the third folding surface 48 continue the drive of the signature through the gap 16.
  • the lateral edges 26 of the signature S are released at the level of the first axial section 30 by the auxiliary clearance 42. This avoids the inadvertent folding of the lateral edges, at the level of the rear edge 22.
  • the folding rollers according to the invention release a large part of the front edge 20, they make it possible to avoid creases at the front edge 20 at the location of the central part 24, and this even at high folding.
