Definitions

  • the invention relates to a control for the folding flap of a flap cylinder in the folding apparatus of rotary printing presses, in which the counter flap can be adjusted to the paper thickness to be processed relative to the folding knife and the folding flap is controlled via a closed curve on a roller lever with cam rollers.
  • a folder on web-fed rotary printing presses is able to produce folding products with different page numbers. Accordingly, the finished specimens also have different thicknesses. This, in turn, must be taken into account in the individual assemblies of the folder. B. in the jaw cylinder, the jaws must hold the different thickness folding products. For this purpose, it is known to make the fixed counter flap adjustable so that the different specimen thicknesses can be folded.
  • the disadvantage of the known design is a more or less one-sided offset flap compared to the folding knife. After the fixed counter flap is reset in relation to the folding knife for thicker products, while the controlled folding flap assumes the same closing point in relation to the folding knife. The consequence of this is that folding differences can occur and that the folding knife loaded on one side damages or even destroys the copies.
  • the object of the invention is to design a control for the folding flap over a closed curve so that the movable folding flap can also be set precisely in relation to the folding knife, according to the respective paper thickness, without requiring a great technical outlay for this.
  • the object is achieved according to the inventive features of claim 1.
  • By dividing the roller lever it is possible to set the folding jaw exactly in relation to the folding knife, even with a control via a closed curve, so that it dips exactly in the middle between the folding jaw and counter-jaw and can produce an exact fold without damaging the folding products .
  • This is particularly important when processing very thin folding products, because the folding flap must be practically closed in relation to the folding knife when immersed in order to grasp the folding product exactly.
  • the subclaims characterize advantageous configurations of the solution according to the invention, which in particular also contribute to the freedom of play of the entire control system, so that the folding accuracy can be increased significantly.
  • a folding jaw cylinder 1 and a folding blade cylinder 2 are provided in addition to other cylinders, which cooperate in such a way that the folding blade 3 of the folding blade cylinder presses the sheet 4 to be folded between the folding jaw 5 and the counter flap 6, after closing the folding jaw receives its cross fold.
  • the cross fold can be provided in the direction of movement of the sheet 4 in the middle of the sheet section.
  • the controlled folding jaw 5 is screwed onto a spindle 7 which is mounted on both sides in the cylinder body of the folding jaw cylinder 1.
  • a roller lever 8 is provided which carries the cam rollers 9, 10 at its other end. These in turn roll on an inner curve 11 and an outer curve 12.
  • the counter flap 6 is fastened on a holder 13, which can be displaced via two eccentric bolts 14 approximately in the circumferential direction of the folding jaw cylinder 1, in such a way that the counter flap 6 can be adjusted to an exact dimension in relation to the folding knife 3.
  • the holder 13 is fixed by means of screws, not shown.
  • FIG. 2 shows the mounting of the folding jaw cylinder, the axis 15 or the axle journal 16 being mounted in the side frame 19 of the machine via a roller bearing 17 and a bearing holder 18.
  • the gear 20 serves to drive the cylinder.
  • the inner curve 11 and the outer curve 12 are fastened centrally on the bearing holder 18 by means of screws 21.
  • the two cam rollers 9, 10 are supported by an eccentric pin 22 in the roller lever 8, the bearing pin 23 for the cam roller 9 being eccentric.
  • the eccentric pin 22 can be rotated via the flattened portion 24, so that the cam rollers 9, 10 are set free of play relative to the inner curve 11 or the corresponding outer curve 12. After adjustment, the eccentric bolt is clamped over the screw 25.
  • the control for the folding flap can be adjusted to different paper thicknesses, whereby to set the folding flap 5 relative to the folding knife 3, the roller lever 8 consists of a part 26 fastened to the pin 7 'of the folding flap and a part 27 carrying the cam rollers 9, 10 26 is pinned via pin 28 on pin 7 '. This in turn is mounted in a bearing 29 in the cylinder body of the jaw cylinder.
  • the front part 27 of the roller lever 8 can be adjusted relative to the fixed part 26 via the eccentric bolt 30 such that the distance between the folding flap and the folding knife can be changed.
  • the zero position of the folding jaw 5 relative to the folding knife 3 is limited by a stop 32 (FIG. 1). After setting the paper thickness, the part 27 is clamped with the part 26 via the clamping screws 32.
  • roller lever 33 differs from that previously described only in the structural design of the roller lever 33.
  • This also consists of a part 34 fastened to the pin 7 'of the folding jaw, which has a dovetail-shaped groove 35.
  • the dovetail 36 of the front part 37 of the roller lever 33 carrying the cam rollers 9, 10 engages in this.
  • the front part 37 can be displaced with respect to the part 34 fixed on the pin 7 'by means of a pin 39 via a threaded spindle 38. In this way, the angle setting of the folding flap 5 can be changed relative to the folding knife 3 and thus the paper thickness can be set.
  • the dovetail 36 is clamped in the groove 35 by means of screws 40.
  • not only the counter flap 6, but also the folding flap 5, which is controlled via a closed curve, can be set precisely in relation to the folding knife 3 in accordance with the paper thickness to be processed, so that an exact folding is achieved without damage of any kind occurring.
