Definitions

  • the invention is based on a cover film with the features of the preamble of claim 1.
  • a cover film known from practice consists of a band-shaped film web endlessly wound on a roll, which is provided with an adhesive strip along one edge.
  • the adhesive is applied directly to the film web. In this way, reinforcement of the film web in the area of the adhesive strip is to be avoided as far as possible, since reinforcements have the consequence when winding the film web into a roll that the roll or roll becomes conical or conical.
  • the wrap is not firm and can fold, which then leads to considerable problems in further handling.
  • the roll in which the cover film is supplied has a length corresponding to the width of the film web.
  • a plastic film for covering motor vehicle seats is known from EP-A-01 87 982. This film only serves as a loose cover and has no precautions with which the film can be attached to the motor vehicle seat.
  • the film which is initially flat, is wrapped in different widths on its two longitudinal edges. Then the length of the cover sheet, which has been pre-folded, is folded together in the middle between the two folding edges that are formed to form a kind of half-tube.
  • the resulting film tape is therefore thicker on one edge than on the other edge due to the different number of fold edges.
  • the cover film is also folded leporello-like inwards in the area of the folded edge that creates the half-tube, so that the same number of layers is superimposed on both film edges before the film web is wound up into a roll.
  • the use of the reinforcement strip in the area of the adhesive prevents the film web from having different thicknesses at its two edges which arise after folding. If, for example, the film web is wrapped only once in the longitudinal direction, the reinforcement strip has the thickness of the film web. As a result, the tape obtained after folding is just as thick in the area of the adhesive as the edge formed by the fold. Winding up to the roll will result in an exactly cylindrical roll. After being rolled up into a roll, both edges are pressed tightly against one another, which prevents dirt from penetrating and also makes the edge less sensitive to damage.
  • the cover film becomes particularly user-friendly if the reinforcement strip is located between the adhesive with which the film is glued to the base and the film web. When using the film, no separate strip has to be peeled off the adhesive. On the other hand, in the wound state, the adhesive is protected from drying out by the subsequent winding layer, because of the same thickness of the Foil on both edges, also in the area of the adhesive, the wrapping layers are firmly on top of each other.
  • the film web can, for example, be folded like a leporello in the longitudinal direction, the next fold being in the vicinity of the adhesive strip.
  • the folding is carried out in such a way that after folding in the area of both edges of the tape obtained, the same material thickness is found and that in any case there is no thicker between these edges of the tape.
  • the figure does not show a covering film 1 to scale to protect surfaces which must not be contaminated when processing adjacent surfaces.
  • the cover film 1 consists of an elongated band-shaped film web 2 which is delimited by two straight side edges 3, 4 running parallel and at a distance from one another. Between these two side edges 3, 4, the film web 2 is folded like a leporello, whereby two continuous folding edges 5, 6 are formed in the longitudinal direction. As a result, the width of the film web 2 is divided into a total of three areas 7, 8 and 9, the areas 8 and 9 being congruent and the area 7 near the side edge 3 projecting beyond the areas 8, 9 with a strip-shaped area 11.
  • the strip-shaped area 11 carries on the side on which the areas 8 and 9 are located after the fan fold, a reinforcing strip 12, the width of which is slightly less than the width of the strip 11 and which extends over the entire length of the film web 2.
  • the reinforcement strip 12 ends laterally at the side edge 3, i.e. neither the reinforcement strip 12 projects beyond the film web 2 nor does the film web 2 project beyond the reinforcement strip 12.
  • the reinforcing strip 12 is permanently connected to the relevant side of the film web 2 by gluing or welding. It carries on its side facing away from the film web 2 an adhesive layer 13 which adheres more strongly to the reinforcement strip 12 than to the documents to 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 over the entire length of the reinforcement strip 12 and thus the film web 2.
  • the thickness of the adhesive layer 13 is negligibly thin.
  • the reinforcement strip 12 has a thickness or thickness which corresponds to the thickness of the two superimposed regions 8 and 9, i.e. the thickness of the reinforcing strip 12 is equal to n times the thickness of the film web 2, where n is the number of folds along which the film web 2 is wrapped or folded.
  • the film web is folded along the two folded edges 5, 6, which run parallel to one another at a distance from one another, i.e. folded twice, i.e. the reinforcing strip 12 has twice the thickness of the film web 2.
  • the stretched-out cover sheet 1, which is folded like a leporello is as thick in the region of the side edge 3 as in the region of the side edge 4, which is located directly above the folded edge 5.
  • the side edge 4 and the folded edge 5 are congruent, so that in turn neither the side edge 4 protrudes beyond the folded edge 5 nor, conversely, the folded edge 5 beyond the side edge 4.
  • the cover film 1 Due to the design of the cover film 1 shown, it can be wound up into the schematically illustrated cylindrical roll 14.
  • the adhesive layer 13 sticks to the back of the underlying layer of the roller 14, so that a separate protective or cover film for the adhesive layer 13 is unnecessary.
  • the adhesive layer 13 sticks airtight but releasably on the back of the adjacent layer from the cover sheet 1 and is thus effectively protected against drying out.
  • the new cover film 1 Since the new cover film 1 has the same thickness practically over the entire width, there are no folds or kinks during winding or the exact cylindrical shape of the roll 14 is not impaired.
  • the only point at which the folded covering film 1 is thinner than it corresponds to the thickness in the area of the reinforcing strip 12 is the gap that is created between the reinforcing strip 12 and the folded edge 6. However, this gap has a negligibly small extent compared to the width of the folded structure.
  • the new cover film 1 When used, the new cover film 1 can simply be unwound from the roll 14 as an endless material. There is no additional protective film for the adhesive layer 13. In addition, similar to a protective film, the adhesive layer 13 detaches from the back of the film web 2 without residues, since it adheres better to the reinforcement strip 12 than to the film web 2 itself.
  • the edge-flush position of the side edge 4 and the folded edge 6 on the one hand and the reinforcing strip 12 with the side edge 3 on the other hand has the advantage that no cavities are formed between the individual turns in the end faces of the roller 14, which would make the edges sensitive to damage.
  • the material of the film web in the cover film 1 can be selected relatively thick without further ado.
  • the film web 2 can also be folded in more than twice or less than twice, depending on the length of the roll 14 to be achieved for a given width of the film web, measured between the two side edges 3 and 4.
