Definitions

  • the invention relates to a longitudinal folding device for a printing material web on a folder of a web-fed rotary printing press according to the preamble of patent claim 1.
  • the invention has for its object to provide a longitudinal folding device which avoids these disadvantages.
  • a printing material web 1 shows a printing material web 1, which is fed to a folding former 4 in a longitudinal folding device of a folding apparatus of a web-fed rotary printing press, not shown, via a guide roller 2 and a driven former roller 3.
  • the printing material web 1 is folded in the longitudinal direction over the tapering lower end of the former 4, which is referred to as the former nose 5, it is guided between the former inlet rollers 6 arranged parallel to one another on both sides of the former nose 5, the resulting fold being compressed and thus in it Shape is stabilized.
  • the former 4 is rotatably supported relative to the machine side walls 7 indicated in FIG. 2 in such a way that the pivot point S is arranged on the side of the printing material web 1 facing away from the former 4.
  • the pivot point S is close to the intersection of two straight lines 8 and 9.
  • the first straight line 8 runs through the upper end of the former edge 10 and is perpendicular on their slope, which is defined by the angle of inclination ß.
  • the second straight line 9 runs vertically (with respect to a horizontal parallel to the machine foundation) through the lower end of the former 4, ie through the former nose 5.
  • the pivot point S lies exactly at the intersection of the straight lines 8 and 9.
  • this arrangement brings about the following advantages when the former 4 is rotated about the pivot point S:
  • a relatively large horizontal adjustment path is possible on the funnel nose 5 on a path approximately parallel to the axes of the funnel inlet rollers 6.
  • the funnel nose 5 hardly changes its height; it only moves a negligibly small distance from the center of the hopper inlet rollers 6. Vertical tracking of the hopper inlet rollers 6 is therefore unnecessary.
  • the upper end of the former 4 moves on a path approximately parallel to the former edge 10; the former 10 is still largely tangential to the periphery of the former roll 3. A tracking of the hopper roller 3 is therefore not necessary.
  • This position of the pivot point S is structurally realized in the exemplary embodiment by means of two pivot levers 11 which are arranged to be movable parallel to the inner sides of the machine side walls 7.
  • the pivot levers 11 each have a bolt 12 on their outer side facing the machine side wall 7, which is received by a bearing bore 13 provided in the respective machine side wall 7.
  • both pivot levers 11 are connected by a rod 14 fastened to their inside.
  • At the rear of the former 4, at least one holder 15 is provided, which engages around the rod 14 and by means of which the former 4 is supported on the rod 14.
  • the former 4 is divided in the middle into two halves 4 a and 4 b (FIG. 2).
  • Each of the halves 4 a, 4 b has on its back a holder 15 a, 15 b, which engages around the rod 14.
  • the brackets 15 a, 15 b have two obliquely obliquely slotted perforations 16.
  • a bolt 17, which projects into the respective opening 16, is anchored in the rod 14 at the level of the openings 16.
  • brackets 15 a, b can also have internal threads with an opposite thread pitch and the rod 14 can have two corresponding sections provided with an external thread of opposite pitch.
  • the pivot levers 11 serve at the same time as carriers for further additional units.
  • a further rod 18 is slidably mounted perpendicular to the former edge 10 between the pivot levers 11 on the front of the former.
  • a cutting, beading or perforating wheel 19 is arranged on this rod 18, which can be adjusted to the former 4 if necessary and cuts, corrugates or perforates the printing material web 1 at the level of the former 10.
  • the pivoting of the former 4 is effected by a spindle rod 20 provided with an intermediate joint, which is articulated at one end to a holder 21 on the rear side of the former 4 and which has a thread at its other end, on which one is held axially in a bearing block 22 Mother 23 is sitting. A rotation of the nut 23 causes the former to pivot.
  • a pivoting of the former can also be controlled in a simple manner from a central control panel.
