Abstract

To produce a leather card, the leather or split leather is bonded to a layer of cardboard, plastics such as polyvinyl chloride (PVC), artificial and imitation leather material, microfibre materials, natural or silicon rubber, nonwovens or feltings, fine wood and veneers, light metal including aluminium, or cork. The laminate is cut or stamped to the required size and shape.

Description

Postcards or postcards are sent worldwide to the recipient to share something or just to send greetings.

Congratulations cards are given to convey good wishes, to congratulate, often with a manually written text and maybe in connection with a present.

They are usually made from fine cardboard, i.e. a wooden product. Like wood, leather is a purely natural product.

Postcards, postcards or greeting cards from leather seems to produce to be uneconomical at first glance. However, it is relatively easy to use leather To connect cardboard, or to fix leather on fine cardboard.

A relatively inferior material from the leather industry can also be used for this process are used, namely the so-called split leather.

Almost all leathers have to have a certain thickness for different types of products to be brought. Leather often has to be very thin and soft and is therefore made using a Split the splitting machine. This split off residual material is thus obtained in large quantities and is considered inferior in the leather industry (partly as waste), especially in the cracks a certain tensile strength is no longer guaranteed.

However, the split leather can be used to make leather cards as postcards, postcards Greeting cards or leather cards can be used for other purposes. Since it can usually be split again, the 2nd, 3rd, or 4th gap can sometimes also be used be used.

A leather card feels soft and natural. It mediates in addition to the recipient a beautiful look and a soft, pleasant grip also the feeling of something valuable to have received.

Certainly can be used to make the leather card as an even more valuable alternative Split leather also normal upper leather can be used in all different variants.  

FOR THE PRODUCTION

In general, the leather card can be made from all types of leather that are available on the leather market (e.g. sheep leather, cowhide, goat leather, pigskin, etc.).

In addition, the leather can be used in all different finishes in terms of tanning, coloring or also surface treatment (e.g. color-printed, embossed, perforated, embroidered leather, etc.) be used.

To produce the leather card, a leather skin, regardless of what type of leather, finishing or coloring, it is either Upper leather or split leather can be used.

Cardboard can primarily be used for the back of the leather card, i.e. the side to be labeled (= paper-like material - stronger than paper, cardboard), but also material of a different type, provided it is suitable for printing and for manual labeling.

Plastic or plastic-like material ("PVC" etc.), synthetic leather, imitation leather, Microfiber material, rubber-like material (natural rubber, silicone, etc.), stronger non-woven fabric, felt-like fabric, fine wood (possibly wood veneer), cork, also light metal (aluminum, etc.) and other material, provided that it can be combined with leather or fixed on leather.

Then such leather cards can be used, but instead of cardboard other material on the leather is fixed according to the same procedure with all the different possibilities are produced like the leather cards with the cardboard attached.

The production of the leather card is now described below using the example of obvious, easy to label material "cardboard":

1) Blanks (rectangular parts) are first punched out of the leather hides (upper or split leather). (see Fig. 1)

The punched blanks in the format approx. 16 cm × 12 cm (= slightly larger than the standard postcard format DIN A 6) are then split again into thin units. (see Fig. 2)

3a) The cards (self-adhesive), provided on the back with a layer of glue according to the procedure a normal sticker (with a silicone paper backing) with good adhesive material will be attached to it Pressed leather units.

You can also use the so-called "double-sided adhesive tape" in a corresponding width (with silicone paper backing), being after pressing it on the cardboard or on the leather simply the paper carrier is then peeled off and the Materials with the remaining adhesive layer are connected by pressing together.

Prior to this, the card is printed on the front with the line print typical of the postcard. (see Fig. 3)

3b) Instead of this application method, the leather can also be sprayed with a firmly adhering spray adhesive (using a spray gun). The cards are then pressed onto the glue-sprayed leather. (see Fig. 4)

4a) The cards with the leather now attached are now cut into the shape of a postcard, normally DIN A 6 = 14.8 cm × 10.5 cm. (see Fig. 5)

4b) Instead of the normal postcard format, other shapes can also be cut or punched by means of cutting or punching machines, such as, for. B. oval shapes, round shapes, shapes with rounded corners and also various unusual shapes (z. B. a double heart, etc.), provided that it is still suitable for sending by mail. (see Fig. 6)

5) The leather cards can now remain on the leather side on the one hand, or on the other hand, printed with countless different motifs or texts of all kinds.

This can be done in the well-known screen printing or offset printing process.

There is also the possibility of the transfer printing process.

Motifs or texts are fixed on a silicone backing paper and can be easily and quickly transferred to the leather with heat and pressure (using an ironing press). (see Fig. 7)

6) Instead of printing on the leather side of the card, you can also embroider it. However, the leather must be embroidered before cardboard fixation (or another material).

Embroidery is easily possible with embroidery machines or large embroidery machines. The current technological status of embroidery offers a variety of possibilities. Personal desires can be taken into account using computers with scanners. A pattern is picked up by the scanner and sent to the computer. An embroidery program can be worked out on the computer, which the Embroidery machine can then embroider into the leather in the form of the desired motif or text.

This also offers the possibility of embroidering motifs or texts for the purpose of advertising. (see Fig. 8)

7) The leather cards can also be printed on the back (the card side to be labeled) stay d. H. without the postcard-typical line print.

In this case, these leather cards can also be used as greeting cards for all kinds of occasions be used.

(e.g. as a birthday greeting card, as a Christmas card, as a wedding or engagement card, as an anniversary card, confirmation or communion card, congratulations card for birth, etc. a.)

Appropriate motifs of all kinds can be printed or embroidered on the leather side of the card or applied in another form. (see Fig. 9)

8) If the leather card is to be used as a congratulatory card, it can also other shapes, or the shapes customary for greeting cards.

This can be the normal "folding card" in all shapes and formats, or the so-called Passepartout card.

The folding card can be completely coated with leather and then folded, whereby the outer side is made entirely of leather, the inner side to be labeled is made of cardboard. (see Fig. 10)

The folding card can also be only partially coated with leather, so that only one piece of leather is fixed in any shape. (see Fig. 11)

The so-called passepartout card is a folding card consisting of 3 sides and 2 folds and a punched-out middle part (window) in various possible forms. (see Fig. 12)

This passepartout card is usually used to take photos or anything else Stick the picture material on one side and then fold it on this side so that the Photo through the punched open space in a framed "look" between the two Sides is liable.

When the other side is folded again, it represents a normal folding card that is in the inner part can be labeled or printed.

Instead of photos or other image material, leather pieces of all kinds can be used in this way fixed in printed, embossed, embroidered, painted or other forms. There is a myriad of variations in terms of motifs or texts.

In general, the shape or format of the folding card or passepartout card can be produced in many different versions.

9a) The leather card can also be produced in this way, so that no Cardboard on which leather is fixed, but only a correspondingly strong, more stable leather is used for this.

It can be z. B. strong, stable cowhide or pigskin (Upper leather or split leather) as it is processed for the shoe industry, be used.

Leather of the stronger kind (without splitting off), but also stable, strong split leather can have so much stability in itself that it can be sent as a postcard or can also be easily used as a greeting card.

The back of this stronger leather can be finely sanded in this case so that they are also easy to use with postcard-typical lines can be printed and is also suitable for direct manual labeling.

You can also use the back of this thicker leather instead of sanding it down, provided with a so-called nappalan layer, so that the fibrous, velor-like Inside of the leather and a smooth, nappa-like surface, or optics. So the back is suitable (the side to be labeled) even better for labeling or printing.  

There is also the possibility of this fibrous, velor-like inside of the leather to be covered with a fine transfer film, also a smooth, nappa-like one Surface or optics are created.

This can be done by means of an ironing press or by a hand iron using heat and some pressure.

These processes, i.e. nappalizing leather or coating it with a transfer film, have long been known in the field of leather production and can be easily and quickly be practiced.

The front of this thicker leather can remain unprinted or printed and modified in all possible variations, equal to Possibilities of the leather card with fixed cardboard.

The parts for the "stable" leather card (without fixed material) can be easily punched out of leather skins or cut out with cutting machines.

This type of leather card production does not use any other material besides leather. (see Fig. 13)

9b) Leather cards made entirely of leather using the above method can also be used instead of stable upper leather or split leather can be made from the so-called "leather fiber" material. Here, the leather is first cut into small fibers or crushed and then bound with natural binders.

This product "leather fiber" is known in the leather industry and available in different Millimeter thicknesses (by splitting) in the form of larger plates or as so-called yard goods (endless) on rolls.

The goods can remain natural (natural colors), colored by applied (sprayed) Color or also by color application by film coating.

These leather fiber boards are ideally suited for the production of leather cards, since there is hardly any waste when cutting or punching them out. (see Fig. 14)

The is also an attractive form for this type of leather card production So-called "knee pads" or "elbow pads" made of leather.

It is an "oval piece of leather" with small punched holes on the edge. These leather parts are intended to be sewn on by hand on those used in clothing parts Places to reinforce the same. (E.g. in the knee area for pants, in the elbow area for jackets or sweaters)

This "knee pads" or "elbow pads" made of leather can be easily punched are punched out of leather skins or leather remnants.

The back can be printed with lines, the front can be plain or printed or bwz. will be modified according to all the options mentioned so far. (see Fig. 15)

The "knee pads" or "elbow pads" can be punched out with a row of holes (small punched holes) on the edge (intended for sewing on by hand) or as a normal die cut in an oval or other shape without a row of holes with small punched holes. (intended for sewing on with the sewing machine)

This means that sending or issuing a leather card in this form has a double one Purpose insofar as the recipient does the same for the above. Purpose or for other purposes can continue to use.

This type of leather card can be made purely from leather or with an annexed one Cardboard or cork or other suitable materials (as already mentioned), because the recipient at the above Use can also detach the fixed material from the leather.

If the "knee pads" or "elbow pads" in this way (with attached material) are made, the leather piece can also be embroidered beforehand with all possible texts or motifs. (see also point 6)

10) As a new method of printing for leather cards in general, but in particular The so-called "laser printing process" is also suitable for stable, strong leather. Motifs or texts of all kinds are burned into the material with a laser beam.

Individual customer requests can be taken into account using computers with scanners. The scanner directs the design to the computer, the computer to a special printer and this in turn directs it to the laser printing machine.

Countless motifs or texts are possible, and the laser beam also prints many different ones Materials (e.g. leather, synthetic leather, wood, plastic or plastic-like materials, aluminum, etc.)

The leather card as a postcard, postcard, greeting card or for other purposes is an interesting thing in terms of recycling.

If the recipient does not want to put the card down as a memento, the recipient can detach the leather from the card and reinsert it for various things.

Pure leather cards can also be used for other purposes. (e.g. as a beverage coaster, beer mat, etc.)

The leather piece can be used for handicrafts or repairs of all kinds. (e.g. as an appliqué on a shirt or for a pair of children's trousers worn through the knee, etc.)

Should the leather nevertheless end up in the garbage or in nature, it "disintegrates" like paper, d. H. nature takes back the leather.
