Definitions

  • the invention relates to a device for applying an adhesive in the form of transverse gluing to a web, in particular for gluing two very fast-running webs, in rotary printing presses, in which a substantial portion of the jacket of an application cylinder rotating about its axis is separated from the web to be glued looped around and the circumference of the jacket is dimensioned according to the distance of the cross-gluing or a whole multiple thereof, the adhesive being guided from a stationary axial adhesive connection to at least one adhesive supply channel extending along a jacket line, rotating with the application cylinder and being in an insert, from which at least one row of outlet openings in the cylinder wall are supplied with the adhesive in a controlled manner.
  • a cross glue unit with these features can be found in DE-C-32 22 335 as known. Then the cross-gluing of a very fast-running paper or fabric web is initiated with the help of a rotating application cylinder, in the circumference of which there are a large number of adhesive outlet openings along a surface line. The adhesive is discharged through these openings at points. The line bonding results from the summation of these points.
  • the application cylinder Because of the high web speed of the webs to be glued, the application cylinder necessarily has a high rotational speed. This leads to problems when the adhesive emerges from the outlet openings. In order not to allow these centrifugal force-dependent conditions to have an effect, the outlet openings are closed from the inside, specifically when the web to be glued does not cover these outlet openings. On the other hand, the web is guided around the application cylinder in a relatively large wrap angle. During the synchronization of the web and the application cylinder in the area of this wrapping, the outlet openings are released from the inside, so that the adhesive can be guided against the web under the influence of centrifugal force. At standstill, the application cylinder is moved into such a position that sealing rollers can be pressed against the outlet openings from the outside.
  • the invention is therefore based on the object to further develop the known cross-gluing unit so that it can be used without the need for complete exchange for generating different distances between the cross-glues.
  • the invention is not restricted to use in gravure printing technology.
  • the invention even offers the possibility of providing an insert for the use of application cylinders of different diameters, the curved outside of the insert corresponding to the curvature of the smallest application cylinder provided. If such an insert is used in an application cylinder whose diameter is larger than that of the application cylinder originally intended for the application, then there is a step due to the different curvatures of the insert and application cylinder on the edge of the guide, which are accepted in certain orders of magnitude can. It is only essential that the area of the outlet openings in use corresponds to the imaginary continuation of the outer surface of the application cylinder, so that no impulses can act on the paper web when the application cylinder is wrapped around it.
  • an application cylinder 1 in connection with guide rollers 4, 5 for the web 6 to be glued is shown very schematically, it being assumed that application cylinders 1 of different diameters are to be used in such an arrangement.
  • Such an application cylinder of the largest circumference and 3 such of the smallest circumference is shown in dash-dot lines with 2.
  • the basic principle of the invention is that a shaft 16 carrying the application cylinder 1, with its drive (not shown in the drawing), its storage and the other control means, should remain in the processing machine at all times and that the body 17 forming the periphery of the application cylinder 1 (FIG. 1) or 22 (Fig. 2) with the shaft 16 rotatably and firmly connected, but can be interchanged.
  • this exchange possibility is created in that a cylinder body 17 which essentially determines the cylinder circumference has a radial recess 18, the width of which corresponds to the diameter of the shaft 16 or a centering body 21 connected to the shaft 16.
  • This cylinder body 17 is firmly connected to the shaft 16 with the aid of a clamping piece 19 which can be inserted into the radial recess 18 and the screw connection 20. It is therefore only necessary to loosen the clamping piece 19 in order to then be able to lift the cylinder body 17 off the shaft 16.
  • These outlet openings 8 are connected to the adhesive feed channel 30, but can be blocked from the inside by a special closure element 31.
  • the adhesive feed channel 30 is connected at the end face of the individual insert 7 to an adhesive channel which is provided axially in the shaft 16. The connecting line of both channels is attached along the end face of the application cylinder.
  • the web 6 is guided with the aid of the guide rollers 4, 5 so that the largest possible wrap around the application cylinder 1 results.
  • the guide rollers 4, 5 since application cylinders of different diameters are to be used, there is the need to arrange the guide rollers 4, 5 in an adjustable manner. With 4 'and 5' the position of these guide rollers in an application cylinder 1 with the largest circumference 2 is indicated by dash-dotted lines.
  • the cross-gluing of the web 6 is carried out, as in DE patent 32 22 335, in such a way that the outlet openings 8 are opened from the inside as soon as the web 6 has covered the outlet openings 8 in the area of the wrap around the application cylinder.
  • the outlet openings 8 remain open during the synchronization of the path 6 and cylinder 1 within this covering area. They are closed before the web 6 begins to lift off the circumference of the application cylinder 1.
  • a line-like transverse gluing on the paper web 6 results from the large number of outlet openings 8 arranged next to one another with a small diameter, which is brought together shortly thereafter with another web.
  • sealing rollers 9 are set against the outlet openings 8 from the outside in order to prevent the adhesive from drying out and the outlet openings 8 from being closed.
  • the individual sealing roller 9 is mounted on an angle lever 11 which is pivotable about the pivot axis 13.
  • the storage of the sealing roller 9 is provided on an upright leg 12 of the angle lever 11, which is constructed so that the guide rollers 4, 5 in their widest position 4 ', 5' do not hinder the movement of the angle lever 11.
  • the position of the pivot axis 13 is chosen so that it comes to lie in the middle between the two end positions of the sealing roller 9, based on the smallest and the largest circumference 3, 2 of the application cylinder 1.
  • two angle levers 11 with sealing rollers 9 are accordingly also provided, which can expediently be adjusted via a common lifting device 14 and via the tabs 15.
  • the invention also encompasses such transverse gluing units in which only one insert 7 per application cylinder 1 is used. In this case, the double arrangement of the angle lever 11 and sealing rollers 9 is unnecessary. Applications are also conceivable where more than two inserts 7 per application cylinder 1 are used. In this case, the arrangement of the angle levers 11 and sealing rollers 9 increases accordingly.
  • an application cylinder 1 with a different design is shown. Thereafter, the shaft 16 has a centering body 21 in a rotationally locking manner, which remains an integral part of the shaft 16 when application cylinders 1 of different sizes are to be connected to the shaft 16.
  • the centering body 21 can be screwed to the shaft, welded, shrunk on, or firmly connected in some other way.
  • Two cylinder bodies 22 (cylinder half-shell) are now connected to the centering body 21, which consequently have the same prismatic guide adapted to the centering body 21. Consequently, such cylinder bodies 22 with the most varied diameters, but with the same centering surfaces, are kept in pairs in order to be able to adjust the cross gluing unit to the desired spacing of the cross gluing.
  • FIGS. 2-4 Because of the high rotational speeds, a special screw connection is selected in the embodiment of FIGS. 2-4, which should also facilitate the assembly and disassembly of the application cylinder 1.
  • the radial screw connection 23 according to FIG. 2 first braces the two cylinder bodies 22 against one another and allows them to come into firm contact with the longer sides of the centering body 21, which is rectangular in cross section. As FIG. 3 shows, two such radial screw connections 23 are provided on both end regions of the application cylinder 1. In the middle there is the assembly screw connection 29 shown in cross section in FIG. 4, which has the sense of firmly connecting the individual cylinder body 22 to the centering body 21, while the other cylinder body 22 is lifted off the centering body 21 after the screw connections 23 and 29 have been loosened .
  • the cylinder bodies 22 are screwed directly to the centering body 21 by the peripheral screw connection 24 and additionally by the cross screw connection 25.
  • the curved outer side 34 of the insert 7 can have a greater curvature than the outer surface of the application cylinder 1, provided that it is ensured that the area surrounding the outlet openings 8 affects the imaginary extension of the surface line of the application cylinder 1 .
  • the insert 7 can be used one and the same insert 7 for application cylinders 1 of different sizes.
  • there is an offset 27 for the insert which - if it is not too large - has no harmful effects on the guide of the web 6 on the application cylinder 1.
  • This offset 27 can be further reduced if, according to the exemplary embodiment in FIG. 5, the curved outer side of the insert 7 is provided with step-shaped steps 33, into which filler strips 35 are inserted. These filler strips 35 have a curved outer surface 37 which corresponds completely to the curvature of the application cylinder 1. Consequently, the offset 36 is significantly reduced compared to the offset 27 in FIG. 2.
  • FIG. 5 also shows the position of the outlet openings 8 in relation to the adhesive feed channel 30, which is essentially closed by a control shaft 32, the diameter of which is smaller than that of the adhesive feed channel 30.
  • a closure element 31 fastened to the control shaft 32 is moved, which covers the outlet openings 8 on the inside and thus prevents the adhesive, which is located in the gap between the channel wall and the control shaft 32, from passing through the outlet opening 8.
  • the insert 7 also has step-shaped shoulders 33, into which a bridging member 40 covering the insert 7 is fitted instead of the filler strips 35 in FIG.
  • This bridging member 40 has the same curvature as the application cylinder 1 on its outer side 42. If the diameter of the application cylinder 1 changes, then only the bridging member 40 needs to be adapted, whereas the insert 7 remains unchanged.
  • the insert 7 has a set back stop surface 39 which contains the outlet openings 8 and against which the bridging member 40 is tensioned. There are continuations 41 of the outlet openings 8.
  • the closure element 31 is in a recessed position according to the wall thickness of the insert 7 and the bridging member 40, but this is not disadvantageous to the Application behavior of the cross glue unit affects.
