Definitions

  • window sticks In the construction sector, the case very often occurs that trades already carried out in the further work processes must not be contaminated. If, for example Window sticks are set, the window sticks be covered so that when subsequently plastering the Facade no mortar or plaster splashes the already assembled Damage window frames. Such window sticks have heights of around 1.20 m, which is why they are correspondingly wide Masking films are required.
  • the length of the slide aligns the width of the window, so that if no special precautions are taken to the slide must be wound on a roll, the length of which Window height corresponds.
  • there are Rolls difficult to handle which is why it from DE-A-41 41 041 is known, the cover film in the delivery form to wind up folded like a fan. This shortens the roll significantly according to the number of folds.
  • DE 38 22 186 A1 describes another possibility reduce the width of the film before winding.
  • a correspondingly wide film web is provided provided with a multitude of small folds during winding, that run parallel to and at a distance from each other continue the length of the film web.
  • the film web is through the folds, seen in the transverse direction, as it were pleated, with between adjacent folds of approx. 1 cm There are wide intermediate areas that are unfolded.
  • the the foil web prepared in this way is on one of its outer sides provided with an adhesive coating and then wound up.
  • the folds are free of glue inside, because in this area the Foil is double. If this film is in place is used and a correspondingly long piece is unwound from the supply roll and separated, the foil pleated across the width is immediately noticeable the entire original length apart since the Wrinkles are not fixed. Such a breakup is undesirable. Furthermore, the adhesiveness of the adhesive the same across the entire width of the web, which also is disadvantageous. Because of the direct order of the No glue can stick to the very thin film great adhesiveness can be used. This would be the There is a risk that the film will tear when removed, because the adhesive is too strong on the surface to be protected sticks. A weak adhesive, on the other hand, favors premature Removing the film from the pad, which is also is undesirable.
  • the adhesive between two adjacent layers of Leporello-like folding initially keeps these folds together.
  • the cover film is wide recorded according to the delivery form, and indeed then if they have an edge on the area to be covered is glued. You can then by pulling out the Fold to the desired length or height of the one to be covered Area to be adjusted while the excess Area of the cover film in the glued fold remains hidden.
  • the film of the invention is therefore largely over the area to be protected run taut and no loose sagging balloon form in which one can easily get caught and the it can be easily torn because it is extremely thin is.
  • the width of the covering film according to the invention thus, without having to be specially tailored, between the width according to the delivery form and the maximum extended length can be varied as desired.
  • the adhesive strips unwind the film not hinder from the role, they are preferably with covered with protective paper or film.
  • the glue that holds the fold together should on the one hand have sufficient adherence so non-attacking wind forces pull the fold apart prematurely, on the other hand, be so weak that the Film does not tear when pulled out.
  • Adhesive is not applied as a continuous web, but in individual, discretely distributed adhesive dots that are evenly distributed over the surface.
  • the cover film in the delivery form in several Fold leporello folds lengthways. In this case, every second fold is glued flat, while the fold between two adjacent folds is open or only slightly secured.
  • the figure does not show the preferred one to scale Embodiment of a cover sheet 1 for protecting surfaces, not when processing neighboring areas may be contaminated.
  • the cover sheet 1 consists of an elongated band-shaped film web 2, the two parallel and spaced straight lines Side edges 3, 4 is limited. Between these two Side edges 3, 4 is the sheet 2 leporello folded, making two lengthways continuous Folded edges 5, 6 arise. This will make the width of the Film web 2 divided into a total of three areas 7, 8 and 9, that trap folds between them.
  • the area 7 stands near the side edge 4 with a stripe-shaped Area 11 over the folded edge 6 over.
  • the strip-shaped area 11 bears on that Page on which the areas are after the fan fold 8 and 9 are a reinforcing strip 12, the Width is slightly less than the width of the strip 11 and which extends over the entire length of the film web 2 extends.
  • the reinforcement strip 12 ends on the side the side edge 4, i.e. there is neither the reinforcement strip 12 via the film web 2 and the film web 2 over the reinforcement strip 12 over.
  • the reinforcement strip 12 is by gluing or Weld with the relevant side of the foil web 2 permanently connected. He carries on his from the film web 2 pioneering side an adhesive layer 13, the adheres more strongly to the reinforcement strip 12 than to the Documents on which the cover film 1 is to be glued. The adhesive layer 13 completely covers that of the Film web 2 pioneering side of the reinforcement strip 12 and runs continuously along the entire length of the Reinforcement strip 12 and thus the film web 2 through.
  • a protective strip is located on the adhesive layer 13 14 for example made of silicone paper, which in the Delivery form d. H. clinging in the wound form on the back of the winding layer adjacent to the inside prevented. It can be easily peeled off around the adhesive layer to release.
  • the film web 2 can also deviate from the representation can be folded more than twice, each according to what length of roll 14 for a given width the film web, measured between the two side edges 3 and 4.
  • the area 9 also protrudes in the area of the edge 3 the folded edge 5 over, so that another strip-shaped Area 15 is formed, which runs parallel to edge 3.
  • A is located on this strip-shaped area 15
  • Reinforcement strip 16 the width of which is approximately the distance corresponds to the edge 3 of the folded edge 5.
  • This reinforcement strip 16 has the same structure as the reinforcement strip 12, i.e. he carries on his of the Film web 2 side facing an adhesive layer 17, and it is in the same way on the film web 2 attached.
  • the adhesive layer 17 is through a protective film 18 covered. If, on the other hand, the winding layers stick one another is desired in order to stabilize the roller 19, the protective strips 14 and 18 can also be omitted become.
  • the two adhesive layers 13 and 17 are located on the same side of the film web 2, so that the film web 2 in the area of the two edges 3 and 4 on one Pad can be glued on.
  • the one folded and coated as described Foil web 2 is in the delivery form for a roll 19 wound up.
  • This adhesive Coating 21 can consist of a continuous film-like Coating or, as indicated, be individual glue dots on the area 8 between the folded edge 5 and the folded edge 6 are applied. The the same effect is achieved if it is adhesive Coating 21 is attached to the area 9. In each If trapped, area 8 adheres to area 9 and is fixed so the fold. Finally, it is also possible to use the area to be evenly provided with adhesive strips.
  • the handling of the cover film 1 according to the invention is as follows:
  • the material of the cover film 1 that is not required is shown in the fold between the two areas 8 and 9 "hidden".
  • the new cover film Since in use the new cover film has an apparent width that corresponds to the required height, it does not form a balloon over the area to be covered, but lies taut over this.
  • the still free side edges will be used if necessary with an appropriate adhesive tape on the one to be protected Fixed area.
  • the new Cover film 1 Due to the adhesive coating 21 can the width of the cover sheet 1 between the smallest width in the delivery form and the largest width with fully extended Adjust folds practically anywhere.
  • the new Cover film 1 has a variable width, so to speak.
  • the width ratio is between the width in the delivery form and the width in the extended Shape firm.
  • the web that forms the cover sheet 1 can can also be folded several times like a fan, whereby the condition is that there is always an even number of Folded edges 5, 6 arise. This also creates one even number of included between corresponding areas Wrinkles, each the folds that are in Direction to edge 3, i.e. upward in use open with the help of an appropriate adhesive coating 21 are held together while the others Folds that are towards the edge 4 and so open down, either completely open or just closed by the securing adhesive 22 being held. Even in the case of using several Wrinkles are in the delivery form between the Areas 7, 8 and 9 formed folds on that side, which points away from the side of the adhesive layers 13 and 17.
  • the embodiment shown also shows the two adhesive strips 13 and 17, on one Side of the film web 9 by the adhesive coating 21 points away or does not wear them.
  • the achieved with it Advantages are mentioned above. But there is more also the possibility of the two adhesive strips 13 and 17 together with the reinforcements 12 and 16 on that Provide side of the film web 9, which by the Adhesive coating carries 21 fold held together.
  • Such a construction of the cover sheet 1 is for large extension lengths an advantage because after pulling out the fold remains on the relevant page of section 9 Adhesive that makes it possible to protect the over the The surface of the covering film 1 additionally in this area to be glued to the surface to be protected, because them in the orientation of the self-adhesive strips 13 and 17 of the area to be protected then faces.
  • the exemplary embodiment shown is insofar as the preferred embodiment, than on both longitudinal edges 4 and 5, the two self-adhesive Strips 13 and 17 are provided for handling significantly simplified. However, it glows easily a that these self-adhesive strips 13 and 17 together with the reinforcements 12 and 16 can be omitted and instead the cover film cut to length 1 with a correspondingly wide masking tape the area to be protected is stuck on by the masking tape partly on the cover 1 and partly is glued to the area to be protected.
  • This embodiment has the advantage that the user himself can choose whether the adhesive coating 21 fold held together by the surface to be protected points away or faces the area to be protected, in the latter case an additional fixation of the Covering film is possible, as described above is.
  • a this fold is inside with an adhesive Provide coating, which stabilizes the fold or is fixed until they adjust to the effective width is pulled out.
  • the film web is on the side and carries one in on the same side Continuous length of adhesive strips.
