Definitions

  • the invention relates to a folding device for folded paper formats, each of said folded paper formats being formed by a sheet of paper defining a front side, and the folded end portions of which are folded down over the center portion of the sheet of paper, occupying the surface thereof and determining a contiguity gap between opposite edges of said folded end portions, said device being of the type that comprises: a first positioning abutment, a first roller and a second roller, which: [i] have mutually parallel shafts located on one same horizontal plane; [ii] are spaced apart, determining a variable width gap; [iii] are rotatable in opposite directions; [iv] the respective upper generating lines of which, in any position of rotation of said rollers, define one same support plane for said folded paper format.
  • Mechanical folding devices comprising a pair of downwardly rotatable parallel rollers which, being located on one same horizontal plane, define therebetween a variable width gap and constitute a support plane for the paper format in the initial folding thereof, which in engagement with a positioning abutment, remains with the center portion thereof centrally positioned relative to the gap defined between the two rollers, which use a special bag provided with a sheet acting as a folding knife, are known. Folding with a special bag for one or two folds works well, but when the bag for the gate-folded format is added, it causes many problems, slowing down the operating speed and substantially deteriorating the quality of the fold.
  • the folding device for folded paper format is characterized in that it comprises: a rigid folding knife for performing vertical reciprocating movements and for passing through said gap, said movements determining a first stroke; two deflectors abutting oppositely and symmetrically said rigid folding knife, capable of being entrained by said rigid folding knife, determining a second stroke shorter than said first stroke, each of said deflectors having a curved working face for engaging the front side of said folded end portions and in this way keeping said folded end portions applied against said pair of rollers; and in that said rigid folding knife is capable of engaging said contiguity space between said opposite edges of said folded end portions and inserting said folded paper format in said gap disposed between said pair of rollers.
  • said rigid folding knife is slidingly mounted in vertical guides and that said vertical reciprocating movements are caused by first ends of two lever arms, which pivot about the second ends thereof; said lever arms being mounted at the second ends thereof on a common pivot shaft and being driven by at least one cam, which is associated with said lever arms via a first rod.
  • a further feature of the invention is that said deflectors are capable of sliding along vertical guides parallel to said vertical guides of said rigid folding knife.
  • said second rotary roller is mounted on pivoting supports which are associated with said common pivot shaft of said lever arms via a second rod pivotally attached to a connecting rod attached to said common pivot shaft, allowing the spacing between said second rotary roller and said first rotary roller to be varied, with the subsequent variation of the width of the gap.
  • the invention also contemplates that said sliding movements of said deflectors are limited by second limiting abutments.
  • said second rod be of adjustable length its adjustment allowing the width of said gap to be regulated.
  • This folded paper format 7 is constituted by a sheet of paper, the folded end portions 7A of which are folded down over the center portion 7B of the folded paper format 7, in such a way that on occupying the surface thereof they form a contiguity space 7b.
  • the rigid folding knife 3 is capable of reciprocating on a vertical plane which is perpendicular to the afore-mentioned plane of support and which is comprised in the variable width gap 2.
  • the amount of the said movement which hereinafter is also called the first stroke, is evidenced by comparing the positions of the rigid folding knife 3 in Figures 1 through 3, in which it is shown in the limit positions of the reciprocating movement.
  • This rigid folding knife 3 frictionally entrains the two symmetrical deflectors 4 and the amount of entrainment, hereinafter also called the second stroke, is shorter than said first stroke, as may be appreciated by comparing Figures 1 through 4.
  • Each of the symmetrical deflectors 4 is provided with a curved working face 4A, having a larger radius than the rotary rollers 1A and 1B. This difference is related to the thickness of the first folded paper format 7, which they engage by the front surface 7a of the folded end portions 7A of the first format 7 in the initial folding thereof. Thereby, the parts 7A are held applied, with gentle sliding on the front face 7a thereof, against the surface of the rotary rollers 1A and 1B, as shown in Figures 2 and 3.
  • the rigid folding knife 3 is mounted at the ends thereof in vertical guides 10 ( Figures 5 to 7) and is driven in its vertical reciprocating movement by two pivoting lever arms 11, which pass through the rigid folding knife 3 with one end 11a thereof through an aperture 12 and are provided with an elongate hole 13 in which there slides a block 14 pierced by a bolt 15, as shown in Figure 5.
  • the second roller 1B is mounted on pivoting supports 19 ( Figure 6) which are associated with the common pivot shaft 16b of the lever arms 11, by a second rod 20 pivotally attached to a connecting rod 21 attached to the pivot shaft 16.
  • These supports 19 allow the separation between the two rotary rollers 1A and 1B and thereby to modify the width of the gap 2 therebetween depending on the work stage.
  • the distance between the pivoting supports 19 and the connecting rod 21 is adjusted threading of the second rod 20 at the ends thereof and the width of the gap 2 is also adjusted by the third abutment 22 so as to prevent the rollers 1A and 1B from unfolding the first folded paper format 7.
  • the folding device additionally comprises a supply belt 23 ( Figure 5), a deflector 24 for collecting the gate-folded formats 9 and placement thereof on a conveyor belt 25.
  • the gate-folded format 9 folding device is adaptable to any of the currently operating folding machines, independently of the width and height thereof.
