 The invention relates to light industry, in particular to the manufacture of art products, obtaining carved leather clothes and others, including toys.

 A stamp is known that contains a punch with a press and a matrix made of the required relief product with grooves for knives, a design from a set of knife blades curved in different ways and connected together along the contour of the drawing by known methods, ejectors and feeders for assembling various stamps / Brief Polytechnical Dictionary, State publishing house of technical and theoretical literature, M., 1956, p. 1074-1076, 523 /.

 A disadvantage of the known stamp is the difficulty of combining the matrix and the punch / knife / with the edge of the embroidered pattern on the skin.

 The claimed stamp is made with a thin strip along the contour of the edge of the figure - from the side of the hole cut out in it and the spring-loaded serrated knife blade vertically across this strip, from the opposite side of the knife blade / from the side of the hole cut out / vertical fixation needles are fixed around the edge of the picture, under them knives, a knife according to the patent of the Russian Federation N 2036080, made of teeth with intersecting cutting edges of adjacent teeth cutting various materials without touching the jumpers between the teeth mi of cut material, which / the teeth - the canvas with teeth / can be arranged in steps, wave-like or in the form of the right or left half of the tooth with bends along the contour of the pattern, its blade may consist of small teeth, and for selecting the stamp pattern its curved knife blades in different ways with holes at their ends are made for screwing to various angles, radial plates, etc.

 The objective of the invention is to simplify the combination of the matrix and the punch with the edge of the embroidered pattern.

 The claimed stamp contains a punch with a press and a matrix made of the required relief product with grooves for knives, a design from a set of knife blades curved in different ways and connected together along the contour of the drawing by known methods, ejectors and feeders for assembling various dies. A design from a set of knife blades - with teeth, feeders for assembling different dies with the same length, bends of knives with teeth are located in overhead, table feeders with a spring, gravity feed and with the orientation drives of the next knife with teeth according to the required degrees of freedom, and with electromagnetic with a slab of a suspended rail conveyor, under the rails of the suspended conveyor there are installed conductors for stacking successively different knives in them, supplemented at the ends with cylinders of magnetic material and cylinders with magnets, and for conveyors being transported, under the known conductor feeders, inclined guide rails are installed at the bottom of the conductor into the conductor of knives from a number of feeders, the knife clamps of which are made disconnected from interaction with the inclined guides.

 A design from a set of knives is attached by springs to a rigid frame with thin walls at the bottom, and the frame is a probe made from the outside of the knives touching and having adjustment screws to create the required clearance and to ensure vertical sliding of the knives along the adjustment screws driven with feedback from the probe sensor - framework.

 On the inner surface of the knives are attached the ears of sliding in them vertically of the needles to fix the sections of the cut-out elastic material and track clips attached individually to the general construction of joining all the needles together.

 The ends of curved knives with teeth are connected to each other by holes at their ends for screws, studs through fitted bars made of magnetic ones.

 The teeth of the knives are made with vertical and inclined blades from their opposite sides, where the inclined blade is longer and the inclined slot is made at the base of the tooth as a continuation of the inclined blade and is located at the base of the adjacent tooth.

 The teeth of the knives are located at different heights - stepwise, undulating.

 Toothed knives for pressure cutting from top to bottom without touching the jumpers between the teeth of the material are fixed in parallel, in the form of a honeycomb structure and with shaped bends to obtain plates, bars, cubes and also with relief shaped faces, as well as mandrels of a mirror relief to complement them to rectangular elements, assembling them various products from various materials and edible - food, taste and artistic designs for furniture.

 The processed material is a plate of wiped and briquetted and non-wiped food products, processed and not processed with heat.

 Bread elements are stacked with other food products in the proportions required by the consumer with the location desired by the consumer between other food products.

 The design of a set of knives with teeth / for rotary cutting / is made curved - rolled into a cylinder, inside of which electromagnetic ejectors are fixed in front of the holes, and this cylinder interacts with a cylinder having grooves opposite the knives.

 It is fixed in the conductor, complemented by handles.

 The stamp is movably mounted in the box, and the walls of the box provide for the laying of solid plates of vegetables and in bulk in any height. The press is made with a vibrator.

The method of filling the relief with polystyrene foam involves embossing the relief, wherein the embossing material is placed above the cavity of the relief mold, on top of this box is placed above the mold cavity, pre-filling the box with polystyrene granules, compressing them together and heating it with steam, up to +100 ^o C .

 In the stamp, the embossing relief under the embroidered section is filled with expanded polystyrene foam placed in a box. A pattern is embroidered on the cut of the skin, a stamp is placed on the cut out skin, the knives of which coincide with the contour of the embroidered pattern, the pattern is trimmed / its edge / along the vertical stripes of the contour of the pattern lying on the skin, then the needles connected to each other are lowered onto the skin to fix it and press the shaped knives connected to each other by jumpers until they cut through the skin along the edge of the embroidered pattern. If an overlock is used to tie the edges of a pattern cut out of leather and other materials, then only knives connected to each other are enough.

The invention is illustrated:

To cut through one single contour 3 / Fig. 1 / selected individual knives 4 with different bends 5, 6 of the available sets of knives with different bends. The ends of the knives 4 have holes with which they are screwed to the bars 7 and connected to the bars with pins and otherwise / clamps, magnets, electromagnets, etc. /. The bars 7 are made in the form of corners, profiled surfaces and parts 8 aligned with each other and knives. Shown / in FIG. 2 / an example of cutting for applique, gluing or stitching cut patterns of one color or embroidered on a background of another color, stitching different patterns together / in FIG. 3 side view. Joined together two groups of 9, 10 knives 4 with the help of bars, 7, 8 - in the form of corners, tubes, including square sections; lattices from them, prefabricated, crossing / enveloping from below, etc. / fasteners 11 with fastenings 12 to the ends of the bars 7, 8. This design of fasteners 1 is located under the movable part of the press. The serrated cutting edge of the knives is made uneven 13 for non-simultaneous contact of the material being cut and to reduce the pressing force when cutting. In FIG. 4 shows a stamp for more precise work, where along the knife 4 the frame - probe 14 is slidily in an upright position touching the edge of the embroidered pattern 1 and the skin 2. The roller - probe 14 encircles the frame 15 and has bending adjustment screws 16 perpendicular to the embroidery edge 1 of the frame - stylus 14 / frame stiffer 15 /. Frame 15 can be lowered onto embroidery 1, leather 2 lies on a flat, cylindrical base 17 / the latter - for cutting a cut and sewn parts of clothing - sleeves are curved in the shape of a sleeve with a stamp /. Under the knife 4 in the base 17 there is a groove-slot 18. Stamps / Fig. 2 and others /. spring 19 for automatic lifting of the knife 4 / stamp / relative to the probe frame 14 or frame 15, where the probe frame 14 is made sliding relative to the adjusting screw 16. Needles 20 for fixing the position of the skin 2 can be connected together by a bar 21 and gliding in the ears 22 It is advisable to attach the needles 20 to the crossbeam 21 using a track lock for manually lifting and lowering each individually needle 20 to correct the area of skin underneath. The stamp is applicable for the manufacture of cubes, composite cubes from any materials used in inventions according to the patents of the Russian Federation 20365616, 2026175, 2053697, utility model N 1436 and from all food products for similar applications / miniature parts and automatic machines for folding from cubes of various products and for preparing raw and processed food for a Moscow-style sandwich, dice designs on plates, trays, etc. / For the initial production of plates, knives 4 are fixed in a stamp parallel to each other. For cutting them into strips of square section, the same stamp was made as for cutting strips into cubes, also applies to multilayer materials and with shaped boundaries between the layers of these materials. Parts of composite cubes have their own stamps for each material or color in the cube / Fig. 5/. The teeth 23 have a long 24 and a short 25 blade with a slot 26 between the teeth 23. A mold 27, behind a layer of skin 2 above which are polystyrene foam granules 28 in a box 29 with a joint clip 30 / Fig. 6 /. Knives are fixed in parallel, in the form of honeycombs, shaped; the material exposed to the knives is made in the form of bars, plates. The result of the stamping process: bars, plates, cubes - also from mashed foodstuffs in pressed ones, including those processed with heat, etc., as well as their programmed joining together.

 The embroidery is also located on the extruded relief of leather, plastic materials 2. To create an embossed relief, there is a mold 27 that is closed with leather, plastic film 2, and on its opposite side there is a box 29 filled with polystyrene granules 28 with a device 30 pressing them to each other During artistic designs, the embossed areas of the skin can be cut off with a stamp, partially with polystyrene foam, gluing other materials instead. The design of the knives is made curved in the form of a bend of the cut material. Along the edge of the probe frame 14 there may be photocells for controlling the probe position and feedback on the drive adjustment screws 16. The conductor with parallel, honeycomb knives 4 is made with two handles for group cutting of vegetables, fruits with one click / Fig. eight/. A jig 31 with handles 32 and feeders 33, 34, etc., with ejectors of the same bend of knives 4 from each feeder with a hanging trolley 35, hanging rails 36 having drive wheels: turret 37, lifting and lowering mechanism 38 for raising and lowering radial drive drives 39 devices plates with electromagnets 40 for attracting magnetic cylinders 41 at the ends of the knives 4, where the lower half of the cylinders 42 is magnetized to attract adjacent knives 4 to the same cylinders 42 / Fig. nine/. Feeders 33, 34 are suspended above a continuously moving chain of conductors 31, and the knife 4 is held by clamps 42, which are reset to the guides 44.

 If the knife 4 with one tooth 23, the blade 24 of which bends around the perimeter of the cut section 3, then a minimal force is applied, while the edges of the probe 14 can move only one sensor / in front of the section of the cut with the knife 4 /. In the jig 31, the parallel blades of the knives 4 are mounted obliquely to create an oblique cut when the oblique knives with the jig 31 slide along the material being cut in the plane of inclination of the cutting knives. Knives 4 are fixed and in several tiers one above the other for sequential cutting. If the walls of the jig 31 are high, like the boxes / probe 14 /, then the box 14 can be filled with completely peeled vegetables or fruits, and for the handles 32 of the jig 31, elongated upwards, cut all these vegetables at once or periodically by pressing the handles 32, mainly by weight the body of the presser, while the height of the blade of the knife 4 may be small.

 Thanks to the invention, cutting processes are facilitated, increased productivity, possibly mass production of dies with various patterns of slots, etc.

For cutting in large quantities or for a sample of leather and other materials of various contours, including embroidered 1 / Fig. 1 / pick up the knives 4 necessary bends / Fig. 2 / and connect them to each other by applying to the ends of the knives 4 selected bars 7, 8, to which the ends of adjacent knives 4 are pressed and screwed or connected with studs. For long-term use, the knives 4 are welded to each other. If there are no knives 4 of the required length with the required bends, make new knives 4 and bend them along the contour of the drawing for cutting / Fig. 2 and 3 /. Under the press, the stamp is pressed against the skin and cut through it: first, with the points of 23 needles, punctures are made simultaneously with all knives 4 / Fig. 2 / or wavy / various uneven vertically /. Edge 13 / Fig. 5/4 knives 4 alternately pierce the skin 2 with their teeth 23 and cut it to notches 26, where on the short side 25 of the blades that did not make an incision due to vertical displacement, the skin cut by the same tooth 23 touches the maximum length blade 24 of the adjacent tooth 23 and they are cut to a continuous slot. To obtain a bas-relief on the skin, its substitute / handbags, ties, other types of clothing /, and under embroidery 1 skin or its embroidered section / Fig. 6 / is applied to the mold 27, and on the opposite side of the skin 2, a box 29 filled with polystyrene foam granules 28 is applied to it and fastened together with clamps 30, laid on the bottom of the container with a load on top of the mold 27 or box 29, filled with water and boiled for several minutes or sent box 29 to the skin 2 and the steam produced by heating water, wherein the granules penopolistirolla 28 podvspenennye or pre-heating the pellets 28 increase in volume and create pressure on the skin 2 to about two molds 27 kg / cm ^2, pressing to from 2 to 27 and the mold pressed against the walls of the molds 27 - to her relief. The relief obtained from polystyrene foam can be stored in the product. On embroidered figure 1, before creating a bas-relief, you can apply a powder of transparent thermoplastic material that impregnates the threads of the picture. The stamp is applicable in rotary machines for continuous cutting of drawings with the subsequent use of overlock machines. The same applies to the manufacture of blocks with ejectors from the honeycomb design of the knives of the obtained blocks, allowing the machine to dial furniture made of wood with foam rubber, polyurethane foam, pieces of leather, for example, a carved back of the sofa. The stamp allows you to cut patterns on the backs of chairs from plywood, boards. To cut 4 knives of the boards with knives, we use a vibrator. As indicated in the description of inventions 1782620, 206561 and other devices of a set of small elements / cubes / products applicable in design bureaus, by designers to create prototypes with subsequent manufacturing of serial products by known technologies, in particular, using these stamps that can be assembled according to the invention N 2050714, if you replace the radio board with knives, or with a programmed set of individual teeth with options for their position and bends on square bases. In FIG. Figure 7 shows the possibility of gluing, threading the skin-background of another color cut out at the top of the pattern, which is held on strips depicting rays of sunlight from Palekh's drawings / on a black background / and ordinary drawings. At the edge of the probe 14, the mounted photocells respond to the gap between the embroidery probe and the edge of the embroidery / contact sensors are possible / and, via feedback with adjustment screws 16, adjust this gap around the entire perimeter of the knives 4. If the knife 4 has a tooth 23 with a blade 24 around the entire perimeter of the figure , then a photocell or sensors automatically moving around the perimeter of the probe is possible. Various stamps for cutting flat materials / leathers, cuts, dough, vegetables, fruit, bread, etc. / can be mass produced in a stream, where from the feeders 33, 34 of FIG. 8 with a plate with electromagnets 40, they take out the next shaped knife 4 for the magnetic cylinders 41, with the help of rotary 37, lifting 38, shifting to the sides 39 of the drives, they orient the knife 4 and by hanging transport 35 on the rails 36 are installed in the jig 31 with handles 32, similarly, the jig 31 is filled other knives 4 joined together to obtain the desired pattern of knives, while the magnetic cylinders 42 above the teeth 23 are attracted to each other for holding until fastened with studs, automatic clamps with a connection to the conductor 31, which with the help of handles 32 on a board, peeled vegetables are cut in the form of plates or cubes / plates can be laid flat and cut into strips, bars, shaped, etc. /. From the suspended feeders 33, 34, the knives 4 are lowered into the clamps 43 / Fig. 9 / with all the drives 38, 37, 39 of the orientation relative to the moving conveyors / not shown / conductors 31 with the inclined guides 4 mounted on them for sliding the blades 4 on them 4 after automatically disconnecting the clamps 43. Similarly for rolled or curved knives for rotation cylinders with knives 4 and pushers between rotary cutting knives, for example, cutting lining drawings on the walls of lacquer miniature boxes / veneer, cardboard, plastic, etc. /. The stamp in the jig 31 with handles 32 with one click on the vegetables laid out on the board is easier and faster to work than various graters. Thus obtained cubes, bars of food products using automatic machines according to US Pat. N 2053697 of the Russian Federation allows different food products to be stacked with each other in the required combinations, proportions and in selected places of certain products, for the elderly - from crushed rubbed food products.
