The invention relates to office equipment, and more specifically to the auxiliary materials used in marking, and can be used in the, tereasa body placed in it a strip of porous material, spanned by lining protective cloth and a holder for the blade teeth for fastening and tensioning of the fabric (EN 2105674 C1, class B 41 K 1/54, 27.02.98).

The disadvantage of this device is a high probability of filling ink cavity between the sheet and the strip of porous material, which will lead to the distortion of the impression and great paint consumption.

Closest to the claimed technical solution in its essence and the achieved technical result is a stamp cushion containing cuvette placed in her unit two-layer media paints in which the upper low-porosity layer and the bottom layer is highly porous (US 5136968 A, class B 41 K 1/54, 11.09.92).

The disadvantages of this technical solution, selected as a prototype, is the leakage of paint on internal walls of the cell on the top low-porosity layer media and as a consequence decrease the quality of the prints, as well as the longevity of stamp pillows and high paint consumption.

The aim of the invention is the provision of a uniform dosed transfer of ink on the surface of the stamp, the ehniki including searching by the patent and scientific and technical information sources and identify sources that contain information about the equivalents of the claimed invention, has allowed to establish that the applicant is not detected similar, characterized by signs, identical to all the essential features of the claimed invention, and the definition from the list of identified unique prototype, as the most similar set of features analogue, has identified a set of essential towards perceived by the applicant to the technical result of the distinctive features of the claimed object set forth in the claims.

Therefore, the claimed invention meets the requirement of "novelty" by applicable law.

To check the compliance of the claimed invention to the requirement of inventive step, the applicant conducted an additional search of the known technical solutions in order to identify characteristics that match the distinctive features of the prototype of the claimed invention, the results of which show that the claimed invention is not obvious from the prior art, a particular applicant identified the impact of the envisaged), the

The essence of the claimed technical solution is that stamp pillow block contains a two-layer medium of paint, in which the upper layer of low-porosity, and lower highly porous, with block media paint further comprises impervious to paint a substrate, and a highly porous bottom layer of the medium of paint made of woven or non-woven thermoplastic material, and the ends of it melted at full height.

A method of manufacturing a stamp pillows by cutting out a block of media paint and fill it with paint, namely, that to cut block the media paints a highly porous lower layer impervious to connect with ink pad, then fill it with paint, covered by low-porosity of the upper layer of the protective insulating film and then cut out with a laser beam unit necessary forms and sizes.

As the media paints using dual layer, composite material, in which the upper layer is a low-porosity, usually 20-45% with a pore size of from 10 to 80 μm, and the lower layer of highly porous, usually 40-85% or more with pore sizes on the order higher than that of the upper layer. It should be noted that these parameters and their autoseastate crucial for the media paints and show the difference in the functional purpose of each layer of the medium of paint: a highly porous bottom layer is a container for paints, low-porosity top layer is semi-permeable barrier which restricts the free flow of paint from the lower high-porous layer.

The upper layer of the medium of paint can be made of woven or nonwoven material, a thermoplastic or thermosetting. For example, the material of the upper layer can be silk, cotton, polyester or similar fabric, non-woven material based on polypropylene fibers, thin felt, etc.

The bottom layer of the medium of paint is made from thermoplastic woven IDN non-woven material based on, for example, polyurethane, polyethylene, polyester (polyethylene terephthalate), etc., thermoplastics, as a pure polymers and copolymers and mixtures of polymers, such as, for example, a copolymer of ethylene with propylene, foamed polyurethane, polybutadiene, natural rubber, etc.

It is obvious also, that the pores in the above-mentioned layers of the medium of paint may not be the same size even in the same layer, and the dispersion of the quantity values then can reach the order of 10. It is also obvious, is raised by the difference of the functions of each layer.

As the substrate material used mainly polymer film from thermoplastic polymers, such as polyethylene, polypropylene, polyester, etc. capable of reliably and without complicating the process be combined with the lower layer of the medium of paint. However, possible embodiments of the claimed ink pads, in which the substrate material is used, for example, cardboard, paper, or plywood veneer impregnated with substances that prevent the penetration of dye.

As the material covering the protective insulating film used in the manufacture of the inventive ink pads, use a polymeric film, for example, polyethylene terephthalate, polyethylene, polypropylene, various copolymers. The film may be of thermoplastic or thermosetting materials, transparent or opaque. In the latter case it is convenient to perform the markup for the subsequent cutting of the medium of paint into separate blocks of the necessary sizes and shapes.

Dual layer media paints get a connection, or a combination of canvases low-porosity and high porosity of the material by gluing, welding or any other known primatel paint, in which the upper layer of low-porosity, and lower high-porous, connect the latter to the substrate by bonding, welding or other known technique, then fill the media on the substrate corresponding paint, covered with a protective insulating film and then thus obtained the workpiece is cut by a laser beam on the stamp pillows desired size and shape. At the same time as the laser light source use a known, commercially available lasers, for example, TROTEC-25ER. It should be noted that cutting the workpiece, filled with paint, not a problem, because the paint under the influence of laser radiation evaporates. In turn, highly porous bottom layer of the medium of paint (and in the case of the upper low-porosity layer from a thermoplastic material and an upper layer) is fused to the full height on the section line laser beam, thus forming a "cell - substrate and melted the ends of the media paints are impervious to paint.

The floor of the upper low-porosity layer in the form of a film is an insulator which, firstly, prevents stamp pillow from drying out during storage, and secondly, protects from dirt when Manito insulating film is removed and declare stamp pillow ready.

Declare stamp cushion and method of its manufacture are illustrated by drawings and diagrams.

In Fig. 1 shows the device of the inventive stamp pillows.

In Fig. 2 shows a diagram of the manufacture of the inventive pillow.

The inventive cushion (Fig. 1) contains two layered media paints 1 in which the upper low-porosity layer 2 and bottom layer 3 of high porosity, coupled with the substrate 4. The ends 5 highly porous lower layer fused to the entire height of the substrate 4.

Works declare stamp cushion as follows.

When pressing the stamp on the pillow from the side of the low-porosity of the upper layer 2 paint (Fig. not shown) contained in the carrier 1 comes from a highly porous layer 3 in the low-porosity layer 2 and plod through it on its outer surface. This surface is ink and accordingly the reddish paint goes on the stamp and marked on the surface.
