Definitions

  • the invention relates to a sheet metal or sheet metal strip for wall or roof cladding, which sheet sheet or sheet metal strip one or more, e.g. Has fold-forming bends and the like with a surface coating in the form of a varnish. is provided, which is covered by a removable protective film on the coating.
  • a removable protective film on the coating.
  • Such sheets coated in the coil coating process mostly consist of aluminum.
  • the protective film which is usually made of plastic, is used to protect the mostly sensitive surface coating from damage during transport and further processing of the roof and wall cladding sheets, which are cut, folded, laid and rebated, during which the inspection of the laid sheets is done is inevitable.
  • the protective film should, on the one hand, perform its function until the assembly work has been completely completed, that is, only when the metal sheets are no longer exposed to the risk of damage due to foot traffic or other impairments after assembly. On the other hand, when executing For lightning protection reasons, fold connections are not worked into the fold seam and remain jammed there.
  • the protective film has been removed and folded back so far from the edge area of the surface-coated sheet before the seams are produced that the sheet areas to be folded were exposed, but the remaining sheet areas were still as far as possible from damage during further assembly or other construction work , Tools, walking or the like. remained protected by the protective film.
  • This for example, through brochures from Alcan Diffusion S.A. (France) known procedure has the disadvantage, however, that the protective film folded back with the adhesive side up is a hindrance to further work and acts as a dirt trap. The dirt together with the adhesive layer exposed to sunlight forms dark adhesive edges that are difficult to remove on the lacquer layer.
  • the film is often removed by hand further than necessary, which unnecessarily exposes areas in some areas, which are then subject to the risk of damage.
  • the object of the invention is therefore to remedy these disadvantages.
  • This is achieved according to the invention in that the protective film has perforations or similar weakenings arranged in a line, which extend approximately along the fold or the folds of the sheet metal strip or strip or at a distance parallel thereto and for separating a film region adjacent to the perforation lines from the others Areas of the protective film are formed.
  • the invention is not only applicable to sheets to be folded for wall and roof cladding, but can also be transferred to color-coated sheets for other uses when the task arises, the protective film only in parts in an intermediate stage of production in an exact line in a simple manner to remove.
  • the perforation line or weakening line according to the invention is provided at a distance from the sheet metal edge corresponding to the fold width. If there are several folds, it can run along a fold-forming fold or at a suitable distance parallel to it, as required.
  • Fig. 1 shows a section through a flat sheet or a flat sheet metal strip 1 made of aluminum with a surface coating 2, which is glued on by a Plastic film 3 is protected.
  • This plastic film is provided with line-shaped perforations 4 which extend at a distance and parallel to the two side or longitudinal edges of the sheet or sheet web. The distance of these perforation lines 4 from the adjacent sheet metal edges is dimensioned such that it is matched to the distance from the sheet metal edges of the fold to be produced later during sheet metal assembly.
  • Fig. 2 shows a sheet metal strip 1 with surface coating 2 and protective film 3, which is folded twice on one longitudinal edge to form an angular fold 5 and folded three times on its other longitudinal edge to form a U-fold 6. Such folds are used to fold two sheet metal strips of this type laid next to one another in the manner shown in FIGS. 4 and 5.
  • the protective film 3 is provided with a perforation line which extends exactly along the first bend, while on the right triple bend 6 in FIG. 2 the perforation line 4 runs at the crease line of the third bend.
  • 3 and 4 show, on average, in a larger representation, two sheets 1, which are folded together with these folds, with surface coating 2 and protective film 3.
