Description

GERMAN

The method of the invention provides, on flat structures such. B. paper, plastic films and others Foils as well as leather and wooden panels or plastic panels to apply color samples that do not have a repeat are subject, however, through certain settings of the recipes and manufacturing conditions Give even, but not repeating patterns. The fabrics thus provided with color patterns Due to their type of pattern, they have a great many areas of application, e.g. B. for wallpaper, decoration material, in bookbinding, portfolio production, bag-making, in arts and crafts, in graphics, in Advertising, for packaging material, in the textile industry, for camouflage surfaces.

It is known to apply plastic and other films, paper webs, textiles, etc. with the aid of pressure rollers can be printed in black and white or in color, with exactly the same pattern after each rotation of the roller returns. There are also methods that cause repeat shifts by mechanical displacement of the rollers which give the report longer intervals, but do not cancel it.

It can be used in this procedure for any pattern only the same rollers are used, which are very expensive to manufacture.

This roller printing process also includes that of German patent specification 27 831, in which a fabric is pressed between two rollers, one of which is engraved.

Likewise, German patent specification 65 520 relates to roller printing by means of blankets.

According to the German patent specification 413 019, printing ink is carried out by means of heavy rollers Pattern fabric with permeable and impermeable areas pressed.

These roller printing processes are available from stencil processes opposite, whereby according to the German patent specification 435 191 threads are used as templates, which are then overmolded.

Furthermore, werglumps or straw are used as templates (German patent specification 343 043).

According to the German patent specification 177 191, fabrics or braids serve as stencils to allow color through to press them on paper.

There are also other printing methods, such as screen printing, cliché printing, linoleum printing, but which are common give all prints subject to the report.

It is also known to subject painted surfaces to a water treatment in a semi-dry state, which creates ice flower-like structures.

It is also part of the state of the art to apply color masses to glass plates and with binders such as To make prints from glue, gelatine, casein or egg white, also from slimy liquids

he reasons to produce marble-like patterns can be deducted. Other methods in which layers of collodion are also applied to glass plates or Zappon lacquer are applied and prints are made from them, also result in marble-like Template.

Also common are the so-called Egg white and paste papers, which are made by hand in your dimensions and also smooth Color samples result.

It is also known to use foam generation surfaces to design colored. Fiber felt films are also used for such designs.

With tear and shrink varnishes, the stresses that arise in the layer during drying are created patterns formed by cracks and fissures.

The subject of the invention, however, is a method, flat structures of all kinds with color patterns in to provide a continuous process without creating a repeat, but with the same setting the Pattern is similar. In contrast to all of the aforementioned methods, the process is based on the Law of capillarity.

Here, a second surface made of little or no glue is applied to the surface to be patterned or prepared paper, such as tissue paper, newsprint or cellulose or even a layer Sawdust or short fibers are placed in such a way that the surface to be patterned is completely and evenly covered is.

This covering layer will, because a'n'atjt a suitable one intensive color solution or dispersion, such as B. pickling, more or less coated, sprayed or dripped; beforehand, if necessary, it can be moistened with water or alcohol-water mixtures, are: The color solutions or dispersions penetrate the cover layer and are through the capillary The nature of the surface is directed in certain directions and flat shapes, which are on the surface structure Leave irregular color patterns.

After the top layer has dried and lifted off, the fabric is provided with the desired color ornament. This process can be repeated several times on the same surface in order to change or reinforce the effects

To protect the colored side, it can be covered with transparent layers in a known manner.

The technical progress of this process compared to the existing and previously practiced pressure and ao There is coloring process of fabrics in that it is possible by this method to create the most varied ornaments in black, white or any Create color combinations on the base without the need for rollers, clichés or stencils or the like. Need to be used. The further progress lies in the fact that the im Flow processes and can be worked at any speed, being versatile shaped Ornaments as well as painterly representational shapes are to be achieved. In contrast to the printing process arise here through a blurring and shading of the shape contours or also a The colors flow into each other with charming patterns that enhance the aesthetic and artistic effect of a. Watercolors to come close.

The variety of color sample options with relatively simple means makes this process very good economical, which also results in a significant technical advance.

To explain the aforementioned method, the following exemplary embodiment is given:

A paper web, ζ. B. wallpaper paper in white or colored primer, is on a conveyor belt directed. For example, a second paper web made of as unprepared, cheap paper or paper stock such as newsprint, cellulose or tissue paper. This upper one Paper web is moistened by known devices with water or mixtures of water with alcohol and then pressed onto the lower surface with brushes, air brushes or rubber rollers. These The double layer slides under a coloring unit, such as a dropper system, and becomes Depending on your requirements in terms of quantity and arrangement, with an intense color adapted to the moistening agent Mistake.

This color is absorbed by the moistened upper layer and passed on by capillary action, whereby, depending on the arrangement of the paint units and the conveyor belt speed, iridescent patterns result, with the same manufacturing conditions in distributing and Size are similar, but always due to the capillary color distribution show deviations again.

These patterns are formed on the upper side of the lower web to be patterned, in this case the Wallpaper strip on which, after drying, the color-distributing Adhere to the upper layer. The dried top layer is then rolled off, peeled off or suction removed.

A protective covering of this paint layer can, if it appears necessary, made in a known manner will.

Plastic films, such as, for. B. polyvinyl chloride films, textile webs, Oilcloth or others.

Likewise, as upper color-distributing layers z. B. also used nonwovens or sawdust will.

When using paper webs as a paint distributor, these can also be used economically after drying Reasons as colored paper z. B. reuse for packaging.
