Abstract

Self-adhesive construction foil with lines (1, 2) as a template for separating components from material plates by sawing or milling on these lines (1, 2) or for engraving, characterized in that the width of the lines (1, 2) is substantially equal to provided cutting width or engraving width is.

Description

The invention relates to a self-adhesive construction foil with lines ( 1 . 2 ) as a template for separating out components from material plates by sawing or milling on these lines ( 1 . 2 ) or for engraving.

State of the art

Construction plans in conventional design are mostly not executed in scale 1: 1 and monochrome black, or black / gray or printed in other color combinations. For economic reasons, more extensive building plans are also printed on two sides.

In the case of very complex construction projects, in this case all sawing lines have to be transferred manually, with great expenditure of time, to the material to be sawn out.

To limit the paper size of complex construction projects to a manageable level, various components are integrated on a larger scale in the drawings. The poor clarity of these blueprints often causes problems for beginners and adolescents in the transfer to the materials used.

This is particularly time-consuming and technically not without problems; suitable carbon paper has to be procured and a 1-by-1 copy template has to be created.

When using blueprints, which are created in scales other than 1: 1, they must be converted accordingly. Also this work of conversion to the scale 1: 1 and redrawing are very time consuming.

All saw cut widths must be taken into account when transferring to the material, so that all parts can be sawed out accurately.

Incorporation of saw-cut widths is compulsory here, as otherwise very large dimensional tolerances occur in the individual elements.

When using sheet metal or plastic materials or glass panes, problems arise when transferring the ink to the material surface, eg. B. in the use of unsuitable carbon papers. Likewise, a sufficiently long-lasting adhesion to the material surface is not ensured.

The sawing, z. B. with a jigsaw, must be done with a certain pressure of the guide plate of the machine on the material surface. Friction of the guide plate on the material surface can lead to smearing or even complete detachment of the cutting lines.

When using water as a coolant, for. B. when sawing certain plastics or sheets or when engraving glass, it comes with the use of carbon paper to problems; the cutting lines or engraving lines can completely open or break.

When sawing components made of plastics or sheets with a smooth or polished surface, it is very easy to affect the material surface, for. B. scratching the material surface in the cutting direction.

Scratches on smooth or polished surfaces must be worked up again in these cases, sometimes with considerable effort.

For reasons of cost, the printing of conventional construction plans is largely monochrome; mostly in black color. To facilitate handling, they are usually folded to a DIN format. Folding usually results in sharp creases that make it difficult to trace and transfer the lines. Kinks can lead to dimensional tolerances.

Task and solution of the invention

OBJECT OF THE INVENTION: The blueprint film is to allow a precise exact cutting out and engraving of glass with decorative motifs (simple graphics or line drawings), even for laymen and beginners, without problems and additional work and scratching the surface.

This object is achieved according to the invention in a self-adhesive construction foil of the type mentioned in that the width of the lines is substantially equal to the intended cutting width or engraving width.

Advantageous embodiments of the invention are set forth in the subclaims.

Preferably, the invention consists of printed blueprints on white PVC film with a matted surface, which can be removed without residue from the sawn-off components or engraved glass surfaces after cutting.

The blueprints allow precise sawing of components by clearly marked sawing lines.

embodiment

In the following, an embodiment of the invention, namely a blueprint film for a nest box with swan design, described in more detail with reference to drawings. In all drawings, like reference numerals have the same meaning and therefore may be explained only once.

No conversion to scale 1: 1 is required; All saw cuts are calculated and printed on a scale of 1: 1 ( 1 = Overview drawing).

All saw foils are stored rolled up until use. Since there are no sharp creases in the film by folding, caused by the dimensional inaccuracies, the accurate and dimensionally accurate sawing of the individual components is guaranteed.

All printed sawing lines correspond to the saw blade widths of normal commercial tools ( 2 : Details off 1 in the scale 1: 1).

Clear distinction of required tools. As a result, the dimensional accuracy of the individual components is guaranteed.

Clear distinction of sawing lines for the tools to be used. All saw foils are printed in monochrome black. People with color vision problems do not have any problems selecting the appropriate tools for the specified sawing lines. By a clear definition of the line type, all sawing lines or edges to be milled or decoration motifs, e.g. B. fonts on components (here, for example, the words "Schwanhausen" on the front nest box swan design) clearly distinguished and assigned to the appropriate tools.

The assigned line types are selected so that a precise sawing of the parts is ensured.

By determining the tools to be used (jigsaw or scroll saw or jigsaw) and the calculation of the different saw cut widths of these tools in the dimensions of the individual components ( 2 ) the precise sawing is ensured with careful execution and a subsequent dimensionally accurate assembly of the individual elements.

The sawing of all individual components takes place exactly on the sawing lines. All final dimensions due to the different widths of the saw cuts have already been taken into account in the design and graphic design of the individual parts.

All marked holes are clearly defined and accurately marked in the individual components.

All holes are clearly marked with size and additional information. When using the specified drill diameter accurate drilling is guaranteed. When the sawing work is carried out carefully, it is ensured that all drill holes on the individual elements fit together when assembling the construction project.

Additional notes on the holes clearly relate to the type, diameter and depth of the hole; drill or pierce ( 3 : more details 1 in the scale 1: 1).

By observing all the hints, it is also possible for laypersons or adolescents with little manual experience to carry out the assembly of a construction project.

After removing the sawblade with sandpaper, the individual components can be directly installed (without further post-processing).

Due to a special surface structure and coating of the self-adhesive film, the drying of the printing inks used is guaranteed.

When cutting sheet metal components that require water as the coolant, the film adheres reliably to the surface of the material. There is no reaction of the color, z. B. dissolution by water or complete reliquefaction. Dimensional tolerances due to swelling of the film do not take place; This ensures precise sawing on the cutting lines with the provided tools.

Reliable adhesion of the blueprint films on smooth plastic surfaces or on polished metal surfaces ensures even in these cases dimensionally sawing of the individual components; with simultaneous reliable protection against scratching of the material surfaces in Sägeschnittrichtung.

Due to the numbering of the individual components of a project, a confusion of similar looking components is excluded.

At the same time, the construction foils reduce the chipping of chips at the cut edges.

Carving work with a fine notch chisel work can be carried out without problem with glued-on foil. Finest details can be realized.

When milling edges (to beautify wood or plastic components) or milling out fonts or ornaments, the film adheres reliably to the materials (plastic, sheet metal or glass) at the milling edges.

For small construction projects for children and adolescents, eg. B. small free-flight models made of lightweight balsa wood, the printed film with a sharp knife (cutter knife) can cut clean and burr-free. The slides are with different elements, eg. B. with rivets, designations or tail, printed and can be glued to beautify the model aircraft on the Balsaflächen.

Children or teenagers thus have the opportunity to build free-flying models with very good flight characteristics.

The glued foil also contributes to the stability of the balsa beads.
