Definitions

  • the invention relates to a device for producing a splice point at the beginning of the web of a web winding according to the preamble of patent claim 1.
  • the object of the invention is to provide devices which considerably facilitate the application of an adhesive tape to the reel and manage with a relatively simple construction effort.
  • the adhesive layer is indicated by dashed lines and corresponding or similar tape parts, for example cover sheets, are identified by the same reference numerals, but with different numbers of dashes.
  • the adhesive tape 1 shows the adhesive tape 1, consisting of the carrier 2 for the adhesive layer 3, the cover foils 4 and 5, which are separated from one another by a longitudinal seam 9 and which adhere to the adhesive layer 3, and the further, narrow, double-sided adhesive strips (also adhesive tape) 7 with a further cover film 8.
  • the adhesive strip 7 can also be replaced by a series of adhesive dots or adhesive surfaces.
  • the adhesive force of the adhesive layer of the adhesive strip 7 located under the cover film 8 is considerably stronger than the adhesive force of the adhesive layer on the other side of this adhesive strip 7. Since with this adhesive strip according to FIG. 2, the adhesive tape on the web end C of the spool or web roll A on the same is attached, when this end of the web is torn off due to the pull of the old web when the two webs are glued together, the adhesive strips tend to stick to the drum and not to the adhesive tape 1. This keeps the thickness of the joint on the doctor element (doctor blade S) of FIG. 3 small . As a result, only a very small amount of coating slip can collect at this joint.
  • the adhesive strip 7 (etc. 6, 10, see Fig. 4; 11, see Fig. 5) follows the splice point at a distance from the circumference of the drum and can therefore be the paper web residues that may get stuck on the doctor element, which arise when the old paper web is knocked off, remove what is very important for the quality of the applied stroke.
  • the "end" C of the web is of course the "beginning" of the reel or web roll A.
  • FIG. 2 shows the state where the adhesive tape 1 is attached on the one hand to the end of the web C of the reel A, on the side facing the inside of the reel and on the other side to the outside B of the same turn of the web.
  • This can e.g. manually by folding back the end of the web C into the dash-dotted position (loop G), in which this end is temporarily attached to the reel by adhesive pieces P.
  • the cover film 5 has therefore already been pulled off on one side of the adhesive tape 1.
  • the other part of the cover sheet 4 is also peeled off from the adhesive tape 1.
  • the arrows in Fig. 3 indicate the direction of travel of the web. It can still be seen in FIG. 3 that the narrow adhesive strip 7 still adheres to the drum, that is to say has been detached from the adhesive tape 1, specifically here at a point where a reinforcing tape 70 is additionally glued to the drum, but which is also can often be omitted.
  • an adhesive tape as just described, may not be available, and overall a method for producing a splice site is proposed and described in detail below using different tape formations.
  • the adhesive strip e.g. 6 or 7, a correspondingly wide adhesive film.
  • the beginning of the web of the new web reel A is turned into a loop G and glued to the web reel with small pieces of adhesive tape P. It Then, for example, the cover film 5 of the adhesive tape 2 is removed and this is glued to the beginning of the web C parallel to the - axial - web edge (beginning of the web equal to the front end of the web) with this adhesive surface. Then, for example, a narrow, double-sided adhesive strip 7 with cover film 8 according to FIG. 1 is glued onto the adhesive tape 2 in the area from the longitudinal edge of the tape to the end that is not glued (since the cover film 4 is still there).
  • the adhesive tape 2 can also be provided with several smaller adhesive strips 6, 7, possibly also 10 with cover foils 8, 8 'and 8' 'on its non-adhesive side.
  • FIG. 5 A further tape formation results from FIG. 5, where a further adhesive tape 11 of the same width as the adhesive tape 2 'with cover film 12 is applied to the two edge adhesive strips 6' and 7 ', which can also have a separation point E, analogous to the separation point of FIG Cover foils 4, 5 and 4 ', 5'. You can then pull off the parts of the cover sheet 12 one after the other and successively fasten the adhesive tape 11 to the winding and thus also the adhesive tape 2 'and thus also the beginning of the web C to the web winding.
  • FIG. 6 shows an adhesive tape with a double-sided adhesive coating. On one side, as previously described, it carries the subdivided cover foils 4 ′′ and 5 ′′ and on the other side a strip-like adhesive layer, as is the case is indicated by the dashed lines, the individual film strips each being covered by a cover film 71 to 74. You can pull off these cover foils one after the other when tightly attaching the beginning of the web C to the web wrap and thus fix the adhesive tape 2 ′′ firmly to the web wrap.
  • an additional adhesive tape according to FIG. 8 is applied to the penultimate turn of the web winding.
  • This is preferably a single-sided adhesive tape 70 ', which is used when the drum has been deformed in the axial direction by the action of moisture and has formed grooves.
  • the adhesive tape 70 ' adheres to the humps of the spool A with a very strong adhesive force and the narrow adhesive strips 6, 7 or 10 or the adhesive tapes 11 (FIG. 5) or 2' 'then adhere very well to this additional adhesive tape 70'. (Fig. 6).
  • the additional tape 70 ' which is glued directly onto the wavy drum - see FIG. 8 - is relatively wide, as can be seen from FIG. 3, so that all narrow adhesive strips 6, 7 can adhere to it.
  • This additional adhesive tape 70 or 70 ' has an adhesive layer with very strong adhesiveness, so that in the splice process, in which the start of the new web, i.e. at high speed, i.e. of the reel A, to which the end of the old web D is connected, this additional adhesive tape together with the narrow adhesive strips 6, 7 remains stuck to the reel, that is to say detaches from the main adhesive tape 2.
  • Fig. 7 a variant of the tape formation according to Fig. 5 is indicated, here a double-wide adhesive tape is used, which has a strong perforation H in the middle, so that by folding in the direction of arrow F the tape formation after Fig. 5 can generate.
  • the small ones are also practical here
  • Adhesive strips 6 'and 7', as indicated in FIG. 7, are to be provided.
  • This adhesive tape is to be provided on the adhesive side completely with cover films divided in the longitudinal direction, as indicated.
  • the design of the cover foils in this case also corresponds to that of FIG. 5.
  • a protruding tail 90 of the beginning of the paper C which arises if the adhesive tape is not adhered exactly to the - otherwise absolutely straight - axial web edge, can subsequently, e.g. easily separated by hand along the adjacent axial edge of the remaining cover sheet 4, 4 ', e.g. be demolished.
  • the adhesive tape 1 or 2 is, for example, partially glued onto the web winding A onto the subsequent turn B, with the narrow adhesive strip 7 or - if there are several - with the adhesive strips 7, 8 or 10 or with appropriate adhesive films, which are applied to the back of the adhesive tape 2.
  • the loop G to be formed is so large that, after the loop has been loosened, the beginning of the web C according to FIG. 2 can still be adhered well to the adhesive tape at the point removed from the cover film 5.
  • FIG. 9 a device for facilitating the attachment of the adhesive tape 1 at the end C of the web is shown.
  • a swivel frame 22 is provided which carries at its upper end a guide and holding roller 13 mounted on bearings 33.
  • This holding roller is a hollow cylinder with jacket bores 34, which are connected to the negative pressure to be generated in the interior of the holding roller 13 with respect to the atmosphere.
  • the web C is held on the holding roller 12.
  • a work table 14 is attached to a pivoting lever 15 which can be pivoted about bearing point 20 and carries a worktop 16.
  • the pivoting lever can be pivoted by a hydraulic lifting element 29 by means of its lifting rod 30 into the position shown in broken lines, in which the working surface 16 on the Shell surface of the holding roller 13 abuts.
  • the hydraulic lifting element 29 is held on a bearing device 32 in the swivel frame 22.
  • the swivel frame can in turn be swiveled by means of a hydraulic lifting element 21 which is fastened on the one hand by means of bearing element 24 in a base plate 19 and on the other hand by means of bearing element 23 on the swivel frame.
  • the swivel frame can in turn be pivoted on the base plate 19 in the bearing 27.
  • the work table 14 with the worktop 16 is shown enlarged.
  • This worktop has a series of holding elements (holding pins) 25, with the aid of which the pieces of adhesive tape can be aligned on the worktop 16.
  • the worktop still has holes 26. Since the work table 14 is designed as a hollow box, which can be placed under negative pressure with respect to the atmosphere by means of connection 41, this negative pressure becomes effective through the bores 26 and holds the pieces of adhesive strip on the worktop 16 so that they swivel upwards when they are swung up the holding roller 13 cannot fall down.
  • the tape i.e. the pieces of adhesive tape, according to the shape of FIG. 1, laid down on the worktop and thus attached to the end of the web C when the work table 14 is swung up.
  • the guide and holding roller 13 or the reel A rotates, the end of the web C is guided into the tacking position with respect to the reel A.
  • the cover film 8 of the narrow adhesive strip 7 is removed beforehand.
  • Fig. 10 it is shown that the worktop has a tear edge 18 which corresponds to the splice edge of the web end C. In the dash-dotted position of the work table 14 of FIG. 4, this edge can be produced by tearing off the excess paper from the end of the web.
  • FIG. 12 shows the position of the adhesive tape 1, in which it is attached by the work table 14 to the end of the web of FIG. 4.
  • FIG. 11 shows a device of the guide roller 13 which does not have the work table 14 of FIG. 9. Instead, a fixed worktop 17 is provided, which is attached to the swivel frame 22 '. Here the adhesive tape 1 or the pieces of the same is applied directly to the end of the web C.
  • the work table 50 is designed as a box which is approximately square in cross section.
  • the work surface on which the adhesive strips are laid down is indicated by 16 '.
  • the inside of the box is hollow and is preferably under an overpressure of the atmosphere, at least in part, at least in the area where the work surface 16 'is located.
  • a connection 41 similar to the embodiment according to FIG. 10 must be provided (indicated here by 41 ').
  • Bores 26 are also provided on the work surface as in the embodiment according to FIG. 10.
  • the fixing pins 25 are also to be provided, which are of course retractable, e.g. by loading by means of a spring.
  • the end of the web of material hangs over the holding roller 13 in accordance with the line shown in broken lines.
  • the work table 50 is pivoted into a position in which the cutting edge 54 cuts off the end of the web of material in accordance with an intended splice edge.
  • the outer surface of the holding roller 13 is preferably rubberized.
  • the adhesive strips which have been laid down on the work surface 16 'are held in place by the negative pressure and, after the work table 50 has been pivoted away, are rotated by means of a swivel arm 15' into a position in which the work surface 16 ', as shown in the figure, is exactly opposite the holding roller 13 .
  • the adhesive strips can then also be in a zigzag shape on the end of the web by a controlled pivoting movement of the work table 50 to be pinned.
  • This pivoting movement can be accomplished either by means of a stepper motor or by means of hydraulic elements with the aid of limit switches.
  • the swivel frame is designated 22 '' here.
  • the work table is designed as a roller 52 formed by a hollow cylinder. It also has the cutting edge 54.
  • the work surface is to be thought of in a position comparable to that in the case of the work table of FIG. 8.
  • the roller 52 forming the work table must have a swivel or rotary drive for a certain swivel or rotary movement.
  • the bending moment of resistance of the holding roller 13 is preferably substantially greater than that of the work table 16, 50 or 52.
