Definitions
- the invention relates to a method for producing and providing adhesive products, in particular labels, whose motifs are printed on a carrier and these are coated on the back with adhesive stains.
- Adhesive products are required today in a variety of forms and designs. As a rule, these are labels or label-like products with a corresponding motif on the back with an adhesive.
- the adhesive ensures good adhesion of the product to a desired object, such as a packaging, bottle or the like.
- the application of adhesive products is so great that in the present case the area of the method according to the invention can only be roughly indicated.
- Labels are primarily produced in such a way that a corresponding carrier is provided on the one hand with the label motif and on the other hand with the adhesive. This is followed by punching, pulling off a grid around the labels, slitting and rolling up, a release paper being applied to the adhesive.
- This release paper can be siliconized paper, for example and protects the adhesive surfaces. When rolled up, it prevents the layers lying on top of each other from sticking and fixes the labels at certain points.
- the label consisting of label motif and adhesive
- the release paper is lifted from the release paper, if necessary, if this has not already been removed, from a carrier grid and sent for further recycling. What remains is the release paper and, if necessary, the carrier grid, both of which must be disposed of.
- the present invention is based on the object
- an adhesive stain is always arranged both on the front and on the back next to a label motif, and then the carrier or a strip thereof is folded into an accordion-like manner to form a label package, adhesive stain lies.
- the label motif should be made from a material that is easy to detach from the adhesive stain or be coated with such a material (release). All kinds of plastics, in particular two-component paints, are available here.
- the label motifs and the adhesive stains are preferably applied in strips in the transport direction of the carrier. Stripes of label motifs and alternate Strip off adhesive stains. Another arrangement is also conceivable, but this is likely to be more complex.
- the paper web should first be printed on both sides of the printing marks that are still wet, and then coated with glue after the printing marks on both sides in one work step.
- the labels can be released from the corresponding grid of the carrier quickly and above all by automatically working machines. For the sake of simplicity, this is done by arranging a die-cut line around the label from the label motif and adhesive stain.
- This stamped line can be molded into the carrier before coating, but a great deal of consideration must be given to this stamped line when coating. It is therefore advisable to form the punch line into the carrier after coating, but before folding it up, from the side of the adhesive stain. Even at a later point in time after folding, it may still be possible to insert the die cut line in the case of thin label packages. The remaining webs are so steep that they guarantee that they will be lifted off from the punch cylinders or punch plates treated with a release layer. The bendie can be co-embossed during or after punching. It may be advisable to cut the carrier into strips before folding if only one strip is required for labeling.
- the result of the folding up is a label package, in which every label motif, with the exception of the top one, is attached to an adhesive stain.
- the removal is now carried out, for example, by means of a suction device which grips the top label and breaks out of the grid in such a way that when it breaks out, only one or a few webs and the adhesive layer are only partially loaded.
- the retaining webs break and the label detaches from the label underneath, it being noted that the retaining webs must be shaped in such a way that their holding force is higher than that of the adhesive stain. This ensures that the label underneath remains in its lattice section.
- the remaining punched section is removed. This is done, for example, by folding away to the side, so that the grating section underneath with the subsequent label comes to rest on top of the label package. Now this label is broken out. Now, however, there is no immediate folding over of this lattice section, since the corresponding folding line to the next lattice section is located beyond the first lattice section.
- the subsequent label is immediately broken out of its grid section, which is possible in a simple manner since the subsequent label with the label
- EfibAiZBLATT RULE 26 tenmotiv upwards in the free opening of the lattice section from which the label has just been removed. Only then is two grille sections removed or folded over.
- FIG. 1 shows a plan view of a printed carrier provided with adhesive spots
- FIG. 2 shows a partially shown top view of the back of the carrier according to FIG. 1;
- FIG. 3 shows a top view of the back of the carrier according to FIG. 2 after a further method step
- FIG. 5 shows a plan view of a label package produced from the label strip according to FIG. 4;
- Fig. 6 is a plan view of the label package after peeling off labels.
- a carrier 1 for example a simple sheet of paper, from which labels are removed at a later point in time, is printed with the motifs of the label.
- a simple P is selected.
- the sheet 1 is printed in longitudinal strips, an adhesive spot 3 being applied between two label motifs 2 at the same distance from the latter, the outer circumference of which corresponds approximately to that of the later label.
- a front side 4 of the carrier 1 is shown in FIG. 1.
- the carrier 1 After the application of the label motifs 2 and adhesive stains 3 in strips, the carrier 1 is rotated and a rear side 5 of the carrier 1 likewise with label motifs 2 and adhesive stain 3 provided in strips. It is important to ensure that an adhesive patch 3 is arranged on the rear side 5 behind a label motif 2 on the front side 4. Any possible label adhesive can be considered as the material for the adhesive spots 3. Furthermore, the label motifs 2 and adhesive spots 3 are generally applied in the direction of transport x of the carrier 1.
- the label motif 2 In the case of the material for the label motif 2, care must be taken that a so-called release is selected which, although adhering to the adhesive spot 3, is easy to detach from it. If the label motif 2 itself does not consist of such a material, the label motif 2 must still be covered with such a material, for example a corresponding lacquer.
- the carrier 1 is punched out around the label motif 2 according to FIG. 3, wherein it can be seen that only a few retaining webs 7 remain in a punching line 6. This allows the label 8 to be easily removed later from the carrier 1.
- the die-cut line 6 also encompasses this adhesive spot 3.
- the carrier 1 can be cut into strips 9 perpendicular to the transport direction x, the cutting lines 10 being indicated by dashed lines.
- the individual strips 9 are separated at a later time.
- each carrier 1 is now folded up like an accordion. This is shown in Fig.4 interpreted, wherein the concertina-like folding takes place, for example, by two rollers, not shown, the circumference of which is covered with wedge rings, the wedge rings meshing and running into one another. Many possibilities are conceivable here and are intended to be encompassed by the present invention. It is only important that a label package 11 is finally produced from the strip 9, in which, due to the arrangement of the label motifs 2 and adhesive spots 3, each label motif always lies on an adhesive spot 3, except for the first label motif. As a result, the label packet 11 is held without a release paper or the like. is needed. The coating with the release ensures that the labels 8 are later easily separated from one another.
- FIG. 5 the label packet 11 is shown enlarged in a top view, the few retaining webs 7 also being recognizable in the punching line 6.
- a suction device is brought in which releases the uppermost label 8 from the label package 11.
- the holding webs 7 break, and at the same time the adhesive stain behind the first label 8 detaches from the next label motif 2.
- a grid section 12 of the strip 9 is folded down, wherein a folding line 13 can also be the folding line for the strip into the concertina-like label packet 11 .
- An empty opening 14 can be seen on the right in FIG. 6, into which remnants 15 of the holding webs 7 still protrude.
- the next label 8a is on the left ready for removal from the label package 11. In the position of use shown in FIG. 6, both the label 8a and the underlying label (not shown in more detail) are removed from the label package 11 before the next two grid sections are folded down.
