DE3737116A1 - Decorative and image-bearing objects made of honeycomb sandwich core layers - Google Patents

Abstract

Decorative and image-bearing objects made of honeycomb sandwich core layers are stacked either from vegetable straws, stalks and leaves or from synthetic straws or bundles and profiles prefabricated therefrom into "packing layers" parallel to the sandwich block, at the same time adhesively bonded straw-to-straw, foamed in or baked in, these sandwich blocks together with commercially available sandwich blocks are artistically prepared by various working and artistic techniques such that image motifs running transversely are produced in the interior, which are cut up into layers, reinforced with transparent cover layers or processed in self-supporting form to form transparent and/or air-permeable image-bearing objects, to give panels, wallpaper, screens and many other attractive articles of a hitherto unknown aesthetic type.

Description

The invention relates to manufacturing processes for transpa pension decor and picture objects from honeycomb sandwich cores, preferably from large grasses, herb stalks and leaves as well Blades of plastic or non-woven materials; in them are these pictorially different materials in terms of color and structure stacked in parallel and glued rigidly or elastically "compact" or "compact" foamed or bound with filling glue or battered and baked so that across the stack block there is a picture motif that leads to arbitrarily thin sandwich cores is cut open; depending on the purpose and intention translucent cover layers or air-permeable fabric glued, or without them, used as self-supporting objects.

With or without a picture, every "honeycomb" sandwich block can also be retrofitted by "injection, application or their mixing techniques ", with a decor or picture motif. For this purpose "flow colors or filling foams" are "injected" in a targeted manner or "applied" colored "threads or stalks" into the cavities, what is possible both artisan and industrial.

In the same way are the cells of "paper honeycomb" or to design similar sandwich blocks in color, for which purpose. Legs Screening device is used, which on the cut surface of a Stack is created to - as in the screen printing process - colors targeted insertion into the cavities, d. H. suck in here. There are also templates for inserting colored threads and straws to be used to serialize image motifs any number of times.  

Because the finished products do not meet the standards of lightweight materials must meet, the stalks etc. according to purely visual Considerations are linked, for what in principle all binders serving the respective purpose are suitable, whether curing or elastic adhesives, synthetic resins and foams as well as gels, gypsum and their filler combinations or simply only baking agents such as B. flour dough. It is essential that this Add chemicals and fire retardants to binders and that they comply with environmental regulations.

State of the art:

It is known that sandwich cores are used as packing between two Cover layers glued and in general lightweight construction used for positive and non-positive composite structures, like the publications DE-OS 28 36 418 and FR 22 71 044 it for Use fleece materials or for grasses. Such Sanwich products specifically serve lightweight engineering, wherever show hidden "support elements" and not "picture objects".

For independence:

In contrast to sandwich cores for lightweight objects, would like the present invention especially the optical peculiarities, make visual use of the structure and color effects of the material. Here, the aesthetic effect of the materials is open Eyes guided and by additional coloring or structuring expanded so that the artistic "means of expression" meaning and The purpose of the invention is, and the "stabilizing means" one have a purpose-based, but "subordinate rank".

But where the proposed plant stems, leaves or they want to serve other materials with "new" requirements serve "structurally" as it is characterized in the claims, since such picture objects can also perform carrying functions.

The invention enables a wide range of qualitatively new products tiger and high quality products, it closes product gaps and opens up completely new branches of craftsmanship and industry.  

The advantages of the invention lie in the qualitatively novel Use of sandwich cores, especially those in which honeycombs or tube and sheet materials stacked in parallel are so that they either go directly to an image block or then with dyes or colored fabrics to various pictures objects are to be designed. However, a particular advantage is to be seen in the fact that with this new procedure the annual renewable but underestimated "natural resources" for novel, alternative culture products can be used.

The artistic processes:

The "visual" and "manufacturing" processes are not par excellence in "prefabrication" and "finishing" subdivide, especially since a design already begins when stacking gen, so z. B. in "packing layers" (where with different colored or differently structured material, with bundles or specially shaped "profile blocks"), or after stacking, by "injection and application" (where with colors, Foaming or glossing agents; colored threads and / or straws Design), whereas the "mixed media" in which the the above types of design work together, removes these limits.

The design of "packing layers" from the different material and color types or individual motifs and bundles provides that:

• a - monochrome and equally structured (homogeneous) details as Color, shape and structure layers are packed together;
• b - image details "split off" from hardened blocks and
• c - single motifs hardened in profile shapes can be used.

The design of the "single-variety blocks" in color and structure (also paper honeycombs and similar sandwich blocks) is preferred if:

• a - only one color or structure should work alone;
• b - a metallization or gloss preparation takes place, or
• c - a pure "injection or application" is carried out.

The design in a "mixed technique" is such that:

• a - an additional stack block prefabricated in "packing layers" punctually "injected" with colors and / or filling foam or
• b - is "applied" with colored threads and / or straws or
• c - the "inking and application technology" is mixed; the latter also applies to "homogeneous" honeycomb sandwich blocks.

Manufacturing techniques and applications:

To narrow down those inequalities that are Stems and leaves would arise, these are part by part or alternately layer by layer against the direction of growth to be stacked so that thickenings are equalized by thinning.

Blocks made up of intersecting layers d. H. in the "Winkelverbund" stacked not only get a special strength, but above all, effective stripes with "shielding and sidelight effect "(two-sided, direct light incidence).

To achieve light-guiding effect, the stalks are either in front or metallized or high-gloss lacquered after stacking.

With matrices and patrices are contour-sharp profile blocks for Form "packing layers" or "chips", which are used to make Images or lamps, for example in the manner of the Tiffany technique.

By coating windows with picture objects made of sandwich cores that still have a top layer are thermal windows and doors with "curtain or blind effect".

When using elastic glue as well as foils or fabrics with recessed kink, are picture objects made of sandwich cores to produce "roller blinds" with different optical effects.

For various interior wall claddings (wallpapers or panels) accordingly apply thin layers on carrier webs, also serial picture objects from sandwich cores as wall pictures.
