Definitions

  • the invention relates to a method for folding at least one paper web and / or connecting at least two paper webs along a common folding and / or stitching line, along which a line-shaped liquid application in the form of folding aid liquid and / or glue is applied by means of at least one application head, and relates to furthermore a device which is particularly suitable for carrying out this method.
  • a liquid is known from EP 0 116 273 A1 which contains pigments which are only visible when they are exposed to assigned visualization agents. This known liquid is only used for marking invisible objects under normal light. It is not necessary to check the order item here, nor is it intended to do so.
  • the measures according to the invention enable for the first time a reliable control of the position of a folding aid liquid or glue application and thus for the first time an error-dependent readjustment of the application device, whereby the avoidance of production errors is very much supported. Since all of this can be accomplished with the aid of a simple measuring process, there is a high level of user-friendliness and thus overall excellent economy.
  • the longitudinal folding device on which FIG. 1 is based consists of a funnel folding device 2 which is arranged over two folding rollers 1 and over which a printed paper web 3 is drawn in order to achieve a longitudinal fold.
  • the web is divided into sections by means of a cross cutting device which can be subjected to a further folding process.
  • a folding auxiliary liquid is applied to the paper web 3 along a line 4, which coincides with the folding line generated by the gap between the folding rollers 1 and the former nose of the former folding device 2 during the folding process.
  • the folding aid liquid is intended to soften the paper material along the folding line, so that an exact, sharp-edged fold can be achieved.
  • the folding aid liquid can be applied contactlessly by means of a hollow needle or, as here, by means of a nozzle 5.
  • the nozzle 5 is received on an application head 6, which is mounted by means of an associated holder 7 on a crossbar 8, which is fastened to the frame side walls 9 of the folder superstructure or the printing machine arranged upstream of the folder.
  • the application head 6, which is provided with switching elements for opening and closing the nozzle 5, is supplied with a folding aid liquid through a feed line 10.
  • the switching elements of the application head 6 can be remotely operated by means of a control line 11 from a control panel 12.
  • the position of the nozzle 5 is by accordingly moving the holder 7 along the crossbar 8 above Width of the web 3 adjustable. In simple cases, this setting can be made manually.
  • an actuating device 13 which can be remotely controlled from the control panel 12 is provided for this purpose and can be controlled via a control line 14.
  • Heated tap water can be used as a crimping aid.
  • absorbent paper such as newsprint, etc.
  • heating to about 30 ° C. is sufficient. You can work at a higher temperature for problem papers. In particularly stubborn cases, chemicals can be added to the water.
  • the folding aid liquid used here also contains pigments that are not visible in normal light and that can be made visible using a suitable visualization agent. Color pigments that become visible under UV light can be used for this purpose. Therefore, only a UV lamp is required to make it visible. This makes it possible to check whether line 4 generated by the folding aid liquid coincides with the folding line or not by making line 4 visible. The fold line is visible anyway. A possible distance can thus be measured.
  • a measuring table 15 is provided in the exemplary embodiment shown, to which a visualization means, here in the form of a UV lamp 16 that can be switched on and off, is assigned.
  • the measuring table 15 is arranged here directly next to the control panel 12.
  • a length scale 17 is provided, by means of which a possibly existing distance a between the visible folding line 18 and the folding aid liquid line 4 made visible by means of the switched-on UV lamp 16 of a folding product 19 placed on the measuring table 15, here unfolded, can be made visible.
  • a folded product 19 is removed from a shingled stream leaving the folding apparatus and, as indicated by a dash-dotted line 20, brought onto the measuring table 15.
  • the length scale 17 can, as here, be installed permanently or arranged loosely.
  • the UV lamp 16 can be provided with a switch button 21 for switching on and off.
  • the application head 6 is then actuated appropriately by the actuating device 13 from the control panel 12 provided with assigned control buttons 22 by the same amount, ie also by the distance a, adjusted.
  • a length scale 23 is also provided in the area of the control panel 12, which is assigned a pointer 24 which can be adjusted synchronously with the application head 6.
  • a digital display could of course also be provided. It would also be conceivable to assign an automatic scanning device to the length scale 17 of the measuring table 15, by means of which the control device 13 can be controlled automatically.
  • an automatic regulation of the position of the application head 6 could also be provided.
  • a measuring device integrated in the folding apparatus for continuously monitoring the correspondence between folding line 18 and folding aid liquid line 4 could be provided, the output of which is used to control the adjusting device 13.
  • stapling products two or more webs are laid on top of each other before folding, folded together and glued along the fold line. Such a strand package is then divided into individual products by cross sections.
  • glue is applied to the webs overlapped by the top web before the folding process along the folding line. This can have a water-like consistency.
  • an application head 6 arranged and constructed similarly or identically to the application head 6 described above in connection with FIG. 1 can be used. Application heads are often used, with which alternative folding aid liquid or glue can be applied. When applying glue, the application head 6 is adjusted depending on the position of the glue application.
  • the line-shaped liquid application for example the glue application
  • the glue application up to date To scan paper web 3.
  • afterglow or non-afterglow pigments can be used.
  • the web 3, which functions here as a pigment carrier, is acted upon in the area of the line-shaped glue application by means of a light source, in the case of afterglow pigments, by means of a flash device and in the case of non-afterglow pigments which only cut open when exposed, by means of an exposure device, such as a UV lamp scanned by means of an associated sensor.
  • the sensor is so oriented that it picks up the reflection during the exposure in the case of non-afterglow pigments and the afterglow light in the case of expediently used pigments, the afterglow light of which, in any case, the lack of light reception by the sensor means a malfunction.
  • the circuit of the sensor is therefore such that an output signal for triggering an alarm device and / or for adjusting the application head 6 is generated when the sensor receives no light signal after activation of the visualization source.
