Definitions

  • the invention relates to a method and a device for folding a paper web onto which a folding aid liquid is applied along the folding line before the folding process.
  • the liquid applied as a folding aid is said to soften the paper fiber, from which a high folding accuracy, a sharply defined folding and thus a small stack height when stacking sheet-shaped folding products are expected without any noteworthy structure in the area of the folding back.
  • cold water taken from the water supply network is particularly useful for certain problem papers, such as printed and / or coated Paper, does not lead to the desired success. Attempts have therefore already been made to increase the effect by adding chemical additives.
  • a subordinate object of the present invention is to provide a simple device suitable for carrying out the method according to the invention.
  • the superordinate task is solved in a surprisingly simple manner in that the folding aid liquid is tap water heated essentially above the normal room temperature.
  • the required temperature depends on the type of paper processed. With softer paper such as newsprint, heating to a temperature of around 30 ° C is sufficient. At Hard paper, the required temperature can be around 60 ° C. If additional chemicals are added in special problem cases, the amount added can advantageously be kept within narrow limits as a result of the elevated temperature, so that there are no unfavorable influences.
  • a heating device preferably in the form of a continuous-flow heater, is simply provided in the folding aid liquid line leading to at least one application head.
  • This is expediently provided downstream of a possibly provided admixing device for admixing chemicals, so that no temperature change is caused by a possible admixture of chemicals.
  • a bypass line controlled by a multi-way valve can simply be provided between the folding aid liquid line and the glue line.
  • the longitudinal folding device on which FIG. 1 is based consists of a folding former 2 arranged over two folding rollers 1, over which a printed paper web 3 or a web package consisting of several such webs is drawn. After the longitudinal folding process, the web or the web package is divided into sections by means of a cross-cutting device, which can be subjected to a further folding process.
  • a folding aid liquid is applied to the paper web on which FIG. 1 is based 3 along the folding line aligned with the gap between the folding rollers 1 and the nose of the former 2, a folding aid liquid is applied. This is applied in the form of a liquid stroke indicated at 4.
  • the folding aid liquid softens the paper material along the folding line so that an exact, sharp-edged fold can be achieved.
  • the folding aid liquid applied in the form of the liquid line 4 can consist of heated tap water.
  • the water temperature used depends on the type of paper used. In the case of absorbent paper, such as newsprint or the like, a temperature of approximately 30 ° C. can already suffice. In the case of problem papers, such as coated and / or printed paper, an excellent result is achieved with a higher temperature in the order of about 60 ° C. If a fixed temperature setting is desired, which should be used in all cases, a fixed temperature of around 50 ° C can be used. If the temperature of the folding aid liquid is not sufficient in particularly stubborn cases, suitable chemicals can be added to the folding aid liquid. Due to the temperature of the folding aid liquid, only very small amounts of chemicals are required. In most cases, however, normal tap water is sufficient due to the temperature control.
  • the folding aid liquid can be applied contactlessly by means of a hollow needle or, as here, by means of a nozzle 5.
  • This is received on an application head 6, which is fixed by means of an assigned holder 7 to a crossbar 8, which is fastened to the frame side walls 9 of the folder superstructure or the printing press.
  • the application head 6 is with corresponding Supply lines 10 and corresponding switching elements 11 are provided for opening and closing the nozzle 5.
  • the position of the nozzle 5 can be adjusted by correspondingly moving the holder 7 along the crossmember 8. In simple cases, this setting can be made manually.
  • a remote-controllable actuating device 12 is provided for this purpose, which can be controlled via a signal line 13 leading to the control panel.
  • the switching elements 11 of the application head 6 can be operated remotely, which is indicated by a control line 14.
  • the nozzle 5 works without contact, ie it is arranged at a distance from the web 3 and is therefore not subject to any risk of contamination and clogging.
  • the application head 6 with the nozzle 5 for applying the folding aid liquid line 4 is located in the area of the run-up of the associated web 3 onto a deflection roller 15 arranged above the former 2, which ensures a tight web guidance and thus a constant distance of the web 3 from the nozzle 5.
  • a deflection roller 15 arranged above the former 2, which ensures a tight web guidance and thus a constant distance of the web 3 from the nozzle 5.
  • due to the contactless application caused by the nozzle it would also be readily possible to accept a certain flutter of the web.
  • glue is applied to the lower webs along the fold line. This can also be heated to facilitate the folding process.
  • the top web which does not receive any glue, is still filled with folding aid liquid in the form of more or less tempered water. Since only either glue or another folding aid liquid is required in the area of each web, the application of glue or water tempered here can be done with Help of one and the same application head 6, which, depending on the operating mode, is supplied with glue or water. Such an application head is therefore, as can best be seen from FIG. 2, provided with two parallel inputs.
  • the number of application heads 6 received on each crossbeam 8 and each assigned to a track 3 depends on the number of folding aid or glue lines required. In the example on which FIG. 1 is based, for reasons of clarity, only one application head 6 is shown, which is required for applying the folding aid liquid line 4. If 8 additional application heads 6 were to be accommodated on the traverse, these could simply be passivated in the present case.
  • FIG. 2 In the block diagram on which FIG. 2 is based, two application heads 6 are indicated, which are to be assigned to two webs 3 to be superimposed. Each application head 6 is provided with two inputs for a folding aid liquid feed line 10a and a glue feed line 10b, of which only one or the other can be activated. In the operating position on which FIG. 2 is based, the lower application head 6 is to be acted upon with glue and the upper application head 6 with folding aid liquid in the form of tempered water.
  • the application heads 6 are each, as already indicated above, provided with a built-in switching element 11, here in the form of a solenoid valve which can be controlled by means of the control line 14, which in each case releases one supply line and closes the other and vice versa.
  • the glue supply line 10b provided with a stub line leading to each application head 6 is fed from a tank 16 provided with two alternately emptying chambers.
  • a filter device 17 is provided in the glue feed line 10b in order to avoid blockages in the area of the nozzle 5, which is simultaneously used to apply glue and folding aid liquid and is therefore very narrow. If heating of the glue, which at the same time serves as a folding aid liquid, is desired in the same way as heating of the regular folding aid liquid, a heating device can be provided upstream or downstream of the filter device 17 or integrated into the filter device 17.
  • the folding aid liquid supply line 10a which also has a spur line leading to each application head 6, can be fed from the water supply network, which is indicated here by a conduit 18.
  • the folding aid liquid feed line 10a leads via a continuous-flow heater 19. through which the folding aid effect can be intensified.
  • an input ie. H. Filter device 21 arranged in the vicinity of the junction from the line network.
  • the folding aid liquid supply line is provided 10a and the glue feed line 10b are connected to one another by a bypass line 22, which branches downstream from the instantaneous heater 19 from the folding aid liquid feed line 10a and opens into the glue feed line 10b in the region of the outlet of the tank 16.
  • a bypass line 22 is provided on the branch of the bypass line 22 from the folding aid liquid supply line 10a and a multi-way valve 24 which can be remotely controlled by means of a control line 23 and by means of which the bypass line 22 can be opened or closed as an alternative to the downstream region of the folding aid liquid supply line 10b.
  • check valves 25 in opposite directions are provided in the area of the glue supply line 10b upstream from the mouth of the bypass line 22 and in the area of the bypass line 22, which are arranged in this way are that the check valve arranged in the area of the bypass line 22 opens under water pressure and closes under glue pressure and the check valve arranged in the area of the glue feed line 10b opens under glue pressure and closes under water pressure.
  • the switching element 11 built into each applicator head 6, designed as a multi-way solenoid valve, is actuated in such a way that the glue supply line is switched off when the web feed is switched off when the bypass line is passivated 10b interrupted and the folding aid liquid supply line 10a is opened, so that even when the bypass line 22 is interrupted, the nozzles 5 are rinsed with pressurized folding aid liquid.
  • the switching element 11 installed in each application head 6 is actuated in such a way that the supply line pressurized with the folding aid liquid is opened and the other supply line is interrupted.
  • the mentioned rinsing of the nozzles 5 or of the entire glue application system can be started as soon as the web speed has dropped below approximately one third of the usual web speed, since waste material is produced anyway during the last outfeed of the material web.
  • the switching elements 11 and 24 designed as multi-way solenoid valves can be controlled via the assigned control lines 14 and 23 by means of a computer processing various operating parameters and / or by hand.
