The invention relates to a method of manufacturing the insulation material of the organic and/or inorganic fibers, equipped or not equipped with organic and/or inorganic binder, and an insulation material may change color and/or shape due to thermal energy, and at least one surface of which perform at least one marked with the designation of the product and/or in the form of markup for cutting.

From application EP 0 795 424 A1 known insulating materials, such as canvases or panels, in the manufacture of a melt of glass or rock and loaded into the shredder. In the shredder melt shredded in a super fine grain fiber, which is then moistened with a binder and, if necessary, by other impregnating compositions. The thus prepared mineral fibers have in this state a certain temperature. Due to the temperature of the fibers and, in particular, due to the mineral binder fibers tend to grip between them. Therefore, mineral fibers immediately after wetting at least a binder is placed on the conveying device, typically a conveyor belt. Formed from mineral fibers such fabric may then be treated in different ways. For example, the painting of the miner is selected fibers upon reaching a certain strength of the material may be subjected to vibrational effects. Typically, the webs of mineral fibers passes through a compression device, a cutting device for cutting the lateral edges, and at least through one annealing furnace for curing the binder.

After exiting the furnace rulonoboev webs of mineral fibers serves to place the winding or cut into individual plates, which are then sent to the packaging device and Packed in standard packing elements.

In the prior art, in particular from DE 298 22 362 U1, it is known that proteolysis insulating material, for example in the form of plates made of mineral fibers, plates made of hard foam or porous concrete, provided with a marking. This marking is applied, usually in the form of color coding with templates and paint spraying, or by inkjet printers. The color coding has a drawback, namely it affects the class of building materials, i.e. Flammability of products.

In order to avoid this influence, in particular, in insulating materials made of mineral wool containing organic binder, use of marking rollers with electro - or gatonegro, the circumference of which bears the marking image or inscription. Marking rollers periodically or permanently place on the canvas of mineral fibers, with heated VA is IKI discolor binder in the product from mineral fibers. This process can occur periodically, as when applying the designation, or continuously, so that the insulating material can be performed continuously inscription with the possibility of discoloration binder hot zones on the surface of the insulating material, resulting in an inscription or design mark are visible on the surface.

To separate the cloth insulation on the individual elements in the form of plates it is known that in the zone of the production line provided corresponding circular saw trimming device, such as a pendulum, circular or band saws, used depending on the products. Such saws can be performed, however, only straight cuts.

Proceeding from this prior art, the object of the invention is to develop a method, according to which the marking and/or separation of the insulating material, it is possible to perform a simple and economical manner, and can be also complex in its contours marking and/or cuts.

The problem is solved in that the insulating material is exposed to at least one laser beam on the surface of the insulating material is applied marking.

As a consequence, the method according to the invention, characterized in that instead of pre the it equipment marking is applied to the surface of the insulation material by a laser beam. The laser beam has a significant advantage, namely, it is easy to control, in particular to achieve it, and adjust depending on the nature of the insulation material. By the way, according to the invention can be processed fibrous insulating materials of organic and inorganic fibers bonded organic binder, such as insulation materials containing glass fibers or organic substances insulation materials with organic coatings or components that are due to thermal energy change color and/or shape and insulating materials made of rigid foam, the marking of which is expressed in change of color and/or swelling of the surface or partial sintering or melting of the recesses on the surface.

When the continuous process of manufacturing insulating material proteolyses form is directed to a laser beam, in order to ensure the continuity of the manufacturing of insulating material. However, there is a possibility of the processing laser beam is made of pieces of insulating material, such as plates, shells, pipes, segments, or other fittings, and manual or automatic feeding of such fittings in the device for processing the laser beam. Continuous processing and insulating material, as a rule, does not occur. On the contrary, it is when this individual processing of individual shaped items, such as shells, tubes, plates, etc.

According to another characteristic of the invention, provided that the laser beam is divided insulating material, in particular the canvas, into segments, in particular plate. Due to this, there is a possibility not only to supply the canvas insulating material markings, but using the same device to cut the cloth insulation on the plate. This saves costs on the production line. In addition, it appeared preferable that the care of a laser beam due to the smaller compared to the conventional components of the mechanical elements significantly easier.

Generating a laser beam of the laser to move predominantly in the longitudinal, transverse and/or vertical direction, and, if necessary, in the angular position relative to the surface of the insulation material. The laser beam is put on the surface of the insulating material by rotating along the three principal axes of the mirror and lens system. The drive of the mirror is effected by motors with an electric drive, receive their drive signals from the control unit. The control unit associated with the installation of electronic data processing (computer), in which the Oh data is stored certain provisions and/or executions marking on the insulation materials. These data are necessary to control the laser beam with respect to its movements and/or intensity. Alternatively, it may be provided that produces a laser beam device mounted for movement with attached optical devices along the three spatial axes. Due to the large number of degrees of freedom of the laser beam can be performed marks and cuts very different form. In addition, the advantage is that, for example, all letters and numbers, and icons can be accomplished by control from a computer and alternately. Next advantage is that can be made plates from mineral fibers, which, for example, on two opposite sides have the contour of the edges that is different from the linear constraints. Thus, can be manufactured, for example, plates made of mineral fibers with defined semicircular grooves in accordance with the requirements of the customer.

The laser beam to produce a solid or glass laser device, mainly with the help of CO2-laser.

The light power of the laser beam is set by the optical devices depending on the magnitude and intensity of the required changes of the material, in particular when performing markings. The advantage is the natural enemy of the laser beam is moved relative to the surface of the insulation material at different speeds. The relative speed is, for example, about 5 m/s

According to another characteristic of the invention, provided that the laser is at least in the conveying direction of the fabric move with greater speed compared with the speed of transportation, mainly 5 m/C. This increased speed is required when performing a large number of markings in the form of letters, numbers, and/or icons, so that all the marking can be performed on a certain section of the path of the transported material.

During the division of the canvas into sections the laser beam is moved in the conveying direction, on the contrary, with a speed that matches the speed of transportation of the canvas, so that you can perform, for example, rectilinear limited incision.

Finally, according to another characteristic of the invention, provided that the displacements and/or output power of the laser beam is controlled by computer setup, input data which is taken from the production control system. A similar relationship of the production control system with control markings or cuts has the advantage, namely in accordance with the wishes of the customer in a simple and reliable way to produce a marketable product.

Extracted from the annealing furnace canvas made of mineral wool with a certain thickness and a certain is uzumasa density served in the exemplary embodiment of the invention to marcinowice-cutter. Marcinowice-cutting device comprises a CO2-variable laser power up to 1500 watts and a wavelength of 1-12 μm, mostly 9-12 µm. The laser beam is put on the canvas of mineral wool mirror. Alternatively, it may be provided that produces a laser beam of the laser is mounted above the conveyor device, which is transported canvas made of mineral wool, dvuhgrosovij the RAM drive, so that the generated laser beam may be induced on the surfaces of mineral wool at a certain angle, which differs from the vertical.

Next, the laser beam can be deflected as desired using electron yustiruemym optical devices such as lenses, lens systems, optical lattice actions or mirrors, and thereby to move on the surface are marked. Due to these optical auxiliary devices, as well as varying distances from them to the surface are marked by changes of the angle and the intensity of the laser beam to change the width and the intensity of labeling.

At the location of the laser on dvuhgrosovij carrier laser beam at the first stage set, with the possibility of its falling at right angles on the surfaces of mineral wool. Dvuhlistovymi the carrier associated with the computer, by means of which control the movements dvuhgrosovij sled. Data to control the movement dvuhgrosovij slide the computer receives from the block coordinate the implementation of the orders to which the introduced species and the number of manufactured plates of mineral wool.

Leaf mineral wool enters the area marcinowice-cutter, and marcinowice-cutting device is in the maximum position in the direction of the incoming fabric made of mineral wool. Immediately upon reaching marcinowice-cutter it starts to perform marking on the surface of mineral wool. This marcinowice-the cutter moves in the conveying direction of the sheet. Once marking is completely fulfilled, marcinowice-cutting device moves in said cutting zone in order to shorten the pre-marked leaf mineral wool on the length of the plate. Then mark the next piece of cloth made of mineral wool and after the cut off marks.

The moving speed of the laser is chosen so that it is considerably higher than the speed of transportation. In addition, the laser power is set automatically depending on markings or cutting process. During the marking process is set, for example, 250 mW, and the cutting process is carried out at a power of 1500 watts.

The brand is ovcu do so, what laser with low energy radiation in the form of a label or image is transferred onto the insulating material. Thus by means of the energy of laser radiation in a narrow range of binder in the insulation material made of mineral wool fades, so at the end of the process you can read the inscription on the canvas of mineral wool. Then the laser energy increases, so that the surface is perpendicular to the cut off certain paths, which can be a also straight cuts. There is also the option to set the laser energy so that the laser cut fabric made of mineral wool not completely, but only to a certain size.

Cloth edges of the mineral wool may be due to the tilting of the laser partially or fully beveled or can take an arbitrary form.
