Definitions

  • the invention relates to a folding device with a longitudinal folding device for producing a second longitudinal fold, which has a frame with side walls running transversely to the folding line and penetrated by a band guide, and with a creasing device having an adjustable mounted creasing roller for producing a running at the point assigned to the second longitudinal fold Creasing.
  • the paper web which has not yet been divided into sheet-like products is grooved.
  • the creasing device is located usually in the area of the folder inlet, for example in the area of the pulling rollers downstream of the former.
  • Devices of this type require two mutually opposite creasing rollers with respect to the paper web, which are cyclically controlled so that the paper web is creased from above on half the length of the subsequently cut and cross-folded sheets and from below on the other half length, so that after the cross-folding has taken place the grooving of the superimposed bow halves is directed in the same direction.
  • This is very cumbersome and requires considerable effort.
  • the control of the creasing rollers can prove to be very susceptible to faults.
  • Another disadvantage of the known arrangements is that the creasing rollers have to be adjusted separately for each change in format to adapt to the new format, which can also prove to be very cumbersome and complex.
  • This object is achieved in a folding apparatus of the generic type in a surprisingly simple manner in that the creasing roller is fastened in alignment with the folding line above the tape guide on the inlet side wall of the frame of the longitudinal folding device.
  • the creasing can advantageously take place much more intensely than in the known web creasing, which is very beneficial to the accuracy achievable in the production of the second longitudinal fold is. Since the creasing only has to be carried out from the side from which the folding knife of the longitudinal folding device also strikes the products to be longitudinally folded, the effort for controlling the creasing roller and the effort for a second controlled creasing roller can be dispensed with.
  • the creasing roller Since the creasing device is fastened to the frame of the longitudinal folding device, the creasing roller is automatically also adjusted when the longitudinal folding device is adjusted laterally. A separate creasing roller adjustment can thus advantageously be dispensed with, which has a positive effect on the ease of use.
  • the advantages that can be achieved with the invention are therefore to be seen in particular in a not inconsiderable simplification with simultaneously guaranteed ease of use and accuracy and thus in particular in an excellent economy.
  • a deflection roller of the belt guide can be provided below the creasing roller.
  • These measures result in simple means.
  • the counter roller assigned to the creasing roller which is a Prevention of the products to be grooved prevented. Since the products rest on the belts of the longitudinal guide running over the deflecting roller, it can prove particularly useful to achieve a full product system underneath the creasing roller and thus to avoid transverse forces if the deflecting roller assigned to the creasing roller has a thickness in the area of the creasing roller '' the tapes of the tape guide compensating support is provided.
  • the belt guide can advantageously have a central belt that supports the creasing roller and is deflected in the area below it.
  • a further advantageous embodiment of the superordinate measures can consist in that the creasing roller is received on a two-armed bearing lever which is pivotably mounted in its central region and which is held by an actuator with its end opposite the creasing roller against the force of a pressure spring supported on the frame.
  • the bearing lever and the actuator can expediently be received on a common support plate which can be fixed on the frame of the longitudinal folding device.
  • the scoring device can thus be easily and simply attached or replaced as a complete assembly. Subsequent installation in folders that have already been delivered is also possible in a particularly simple manner
  • the folding apparatus shown in FIG. 1 which is supposed to be arranged downstream of a web-fed rotary printing press, consists in a manner known per se of a folding jaw cylinder 1, which works together with a folding knife cylinder 2, against which a cutting roller 3 is employed to form a cross cutter.
  • the paper web 6 drawn to produce a first longitudinal fold by tension rollers 4 via a former 5 is divided into arcuate products in the contact area by cutting roller 3 and the folding knife cylinder 2, which is also equipped with cutting knives, at its front end by the folding knife cylinder Linder 2 provided punctures and transferred in the contact area between the folding knife cylinder 2 and the folding jaw cylinder 1 attached to it with the help of the folding knife of the folding knife cylinder 2 to form a transverse fold to the folding jaws of the folding jaw cylinder 1.
  • the products removed from the folding jaw cylinder, thus once longitudinally and once cross-folded, are fed to a sword folding mechanism designated as a whole as 7, which comprises a folding sword 8 that can be moved up and down and two folding rollers 9 with their gap underneath.
  • the products introduced by the folding blade 8 between the folding rollers 9 enter a paddle wheel 10 arranged below the folding rollers 9 and are deposited therefrom onto a downstream processing station, for example a delivery belt 11 leading to a facet delivery or the like.
  • the folding blade 8, the folding rollers 9 and the paddle wheel 10 are accommodated in a frame in the frame 12 of the folding apparatus which is adjustable transversely to the folding line defined by the folding blade 8 and has side walls 13 extending transversely to the folding line.
  • guide rails 14 assigned to the side walls 13 can be provided in the folder frame 12.
  • the products removed from the folding jaw cylinder 1, for example by means of a lifting tongue 15, are transported to the sword folding unit 7 by a belt guide 16 with upper belts 17 and lower belts 18, between which the products are accommodated.
  • the tape guide 16 runs between the folding blade 8 and the folding rollers 9.
  • the side walls 13 are for this purpose with a corresponding let slots 19 provided.
  • the belt guide 16 consists of two adjoining belt sections.
  • a creasing device designated as a whole with 20 is provided, which is provided with a creasing roller 21, under which the products to be creased are passed.
  • the creasing device 20 is fastened in alignment with the folding line defined by the folding blade 8 or the gap between the two folding rollers 9 arranged below it, above the belt guide 16, on the inlet-side side wall 13 of the frame of the longitudinal folding device 7 which is adjustably mounted transversely to the folding line.
  • the creasing roller 21 is thus automatically adjusted to the fold line and is automatically adjusted with each adjustment of the longitudinal folding device 7.
  • a deflecting roller 22 of the band guide 16 is provided, which serves as a fixed creasing counter bearing.
  • the bands 17 and 18 of the band guide entering the sword folding mechanism are laterally offset from the fold line defined by the folding sword 8 and thus also laterally from the creasing roller 21.
  • the latter can be provided with an attached or molded ring, the thickness of which corresponds to the belt thickness.
  • a central belt 23 is provided which is deflected in the area below the creasing roller 21 and therefore does not run in between the side walls 13.
  • the creasing of the products takes place in the area of the inlet to the sword folding unit 7. Since the already cross-folded products consist of several layers, so that a comparatively soft sheet package results, the creasing roller 21 can be relatively strong without fear of damage to the products be pressed against this, which advantageously results in a sharp creasing and thus a high accuracy in the manufacture of the second longitudinal fold can be expected.
  • the grooving device 20 forms an assembly which is mounted on a support plate 25 which can be fixed by screws 24 to the side wall 13 on the inlet side.
  • a two-armed bearing lever 26 is provided, which engages with its end opposite the creasing roller 21 in an actuator 28, by means of which the pivoting position of the bearing lever 26 and thus the pressing position of the creasing roller 21 can be adjusted against the force of a pressure spring 29.
  • the pressure spring 29 is received on the frame side in an associated bore 30 of the holding plate 25.
  • an adjustable sleeve 31 is provided for receiving the pressure spring 29.
  • the sleeve 31 is designed as a threaded sleeve which engages in an associated thread of the bearing lever 26 and which is provided with a hexagon recess 32 for attaching an adjusting key.
  • the actuator 28 is designed in the illustrated embodiment as a pivotally mounted screw on an associated bracket 27 of the support plate 25, which passes through the assigned arm of the bearing lever 26 and is provided with an adjusting nut, in the illustrated embodiment of a lockable double nut arrangement 33, on which the assigned arm of the bearing lever 26 is present. By opening the double nut arrangement 33 and turning the adjusting nut, the creasing roller 21 can be raised or lowered more or less.
  • the associated arm of the bearing lever 26, as can best be seen in FIG. 3, is provided with a fork 34, the legs of which encompass the creasing roller 21.
  • a fork 34 the legs of which encompass the creasing roller 21.
  • the creasing roller 21 is received on a pin 36 which is attached to a screw 35 screwed into one of the fork legs and which engages with its end in a bush 37 which penetrates the other fork leg and which can be fixed thereto by means of a screw and at the same time serves as an adjustable bearing stop for the rolling bearing 38 receiving the creasing roller 21.
  • FIG. 3 also clearly shows that it is expedient to adjust the height of the belts 18 running on the deflecting roller 22 assigned to the creasing roller 21 by means of a hoisted ring or, as here, by a between the belts 18 to compensate for the middle band 23.
  • the creasing roller acting from the same side as the folding blade 8 on the products passed beneath it is sufficient.
  • the creasing roller is not driven and is simply taken along by the products that pass beneath it. But it would also be easily conceivable to provide the creasing roller with a positive drive.
  • the tape guide 16 can be provided with a tape kink 40 in the area in front of the creasing roller 21. This is expediently arranged such that the product fed to the creasing roller 21 is already kinked as soon as the front edge of the product runs under the creasing roller 21. Lateral slippage is hereby excluded with certainty.
