Definitions

  • the invention relates to a device for pressing the fold of folded paper products, in particular printed products, which are moved by means of a conveyor.
  • devices for pressing the fold of folded printed products have long been used. These devices are designed in such a way that the shingled stream resulting from the printing press, for example on a ribbon conveyor, in which the fold of each newspaper forms its leading edge and overlaps part of the preceding newspaper, is passed between one or more successive pairs of nip rollers. The fold is pressed as it passes through or through the nips. The time during which this pressure is exerted on the fold is very short and the shorter the higher the conveying speed of the shingled stream.
  • paper is a material that has a certain ability to recover, the very short pressing time in the known devices is not sufficient to permanently press the fold in such a way that it has its smallest possible radius of curvature and, above all, maintains it .
  • the proposed device has the features defined in the characterizing part of patent claim 1.
  • the device 10 shown has a conveyor 11 which is provided with grippers 12 arranged at regular intervals from one another.
  • the grippers 12 are in turn attached to a conveyor chain (not shown) guided in a hollow rail 13.
  • the structure of the conveyor 11 preferably corresponds essentially to that described in US Pat. No. 3,955,667 (largely identical in content to DE-OS 25 19 561 3), but with the difference that in the present case the jaws of the grippers 12 stand approximately at right angles to the course of the hollow rail 13.
  • each of the grippers serves to grip a newspaper Z at its edge (flower) opposite the fold (collar). The newspapers Z are thus transported hanging with the fold pointing downward in the direction of the arrow 14.
  • the arrangement 17 is explained below mainly with reference to FIGS. 2 and 3. It has two self-contained, in hollow rails 19, 20 lying parallel to one another (FIG. 2) with an essentially oval shape (FIG. 1).
  • a link chain 24, 25 (only indicated by dash-dotted lines in FIG. 2) is guided via rollers 21, 22, 23 (FIG. 3), which each have a driving sprocket 26 and a deflection wheel 27 (FIG. 1) are performed.
  • the driving sprockets 26 are driven together by the drive unit 15 in the direction of arrow 26 '.
  • each of the pivots of the rollers 23 carries a laterally projecting arm 28.
  • Each of these arms 28 also forms the one articulated pin of a four-link articulated gear 29 with four links of the same length with respect to the link chains 24 and 25 and also carries one end of the press jaw 30, which is immobile relative to the link chains 24 and 25.
  • Each of these immovable press jaws 30 is one of the pressing jaws 31 which is movable relative to the link chains 24, 25, the respective pairing being indicated in FIG. 2 by the curly brackets 32. It can be seen that during each fixed press jaw 30 from the boom 28, i.e.
  • the associated, movable press jaw 31 is supported by the (movable) pivot pin 33 of the two adjacent, opposed joint gears 29 opposite the immovable pivot pin.
  • the movable press jaw 31 of a pair is coupled to the articulated gear 29 which precedes the articulated gear 29 which carries the associated fixed press jaw 30.
  • the force of the compression springs 40, 41 is dimensioned such that it overcomes the counteracting force of the coil springs 44, 45 of all of the articulated gears 29 located in the area of the links 38, 39. Due to the fact that the baffles 38, 39 can be displaced from one another counter to the action of the compression springs 40, 41, there is also an automatic adjustment of the amount of the infeed movement of the movable press jaws 31 to the assigned fixed press jaws 30 and thus an adjustment to the thickness of the paper products with a simultaneous increase the pressing force.
  • elevations 46, 47 running transversely to these can be provided on the clamping surfaces 30 ', 31' of the pressing jaws 30, 31.
  • the device described is particularly advantageous because the frame supporting the pressing jaw arrangement 17 with its drive 15 can be set up at different locations along the same independently of the conveyor, and can even be used with an existing conveyor, provided that this - as mentioned - with controlled grippers for grasping one copy at the edge opposite the fold.
  • the length of time during which the folds are pressed depends on the conveying speed of the conveyor 11 and on the length of the upper run of the chains 24, 25 as well as scenes 38, 39. By appropriately dimensioning these sizes, the duration of the pressing can be changed in a simple manner.
