The invention relates to a method of manufacturing subjected to further processing profiles of elastic material, in particular sealing profiles for the construction industry, which ekstragiruyut and then vulcanizer salt melt at a temperature 170-330oWith and on which is printed the necessary data and, in addition, put facilitating Assembly coating and then dried it. In addition, the invention relates to an apparatus for the manufacture of lacquered for lubrication of profiles for the construction industry, containing an extruder, molten salt, as well as coating and printing area. Finally, the invention relates to a profile for mounting, in particular to a window profile for the construction industry with a rack profile and the sealing body, the surface of which is provided to facilitate installation of the floor.

Consisting of rubber, plastics or corresponding mixtures profiles required in various fields, for example, among others in the construction industry for Windows and there like for mounting the glass in the actual profile, the for example, from EP 0560214 profiles ekstragiruyut and then vulcanizer salt melt to then be subjected to further processing, in particular, printing and applying facilitating Assembly and further processing of the coating. As cover for such profiles to date has used a silicone emulsion, which should do the actual window profile, more flexible and generally more easy to handle. However, the disadvantage of this coating of silicone emulsions is that these emulsions have only a limited storage stability, that during the process of making almost impossible to change, so it is impossible to take into account the wishes of the customer or can be taken into account with correspondingly high costs, and that, above all, the use of silicone emulsion leads to contamination of production equipment and personnel when handling coated with silicone profiles. Not only the manufacturer is forced to deal with emerging contaminants, but also working then the dressers as silicone emulsion all contaminates. Even a housewife in the next few months will be required when carrying out cleaning to fight with the remnants of the silica manufacturing profiles, in particular, window profiles with a coating that allows for easy and clean handling and ensures long-term stability during storage. In addition, there should be created the profile.

The task is solved according to the invention by the fact that the profiles are manufactured from not repulsive lacquer material and after exiting the extruder and before entering the molten salt cover applied to not vulkanisierung surface varnish for lubrication.

Although such coating varnish for lubrication fundamentally known from the automotive industry, and there profiles first ekstragiruyut and vulcanizers and only then subjected to subsequent processing, i.e., instead of the silicone emulsion provided with a layer of varnish for lubrication. Then nail the lubrication needed to be cured by appropriate devices, which not only requires a more substantial investment, but also requires a lot of space and also time, since the curing of the lacquer must be done very carefully and with respect to the entire surface of the profile.

In contrast, in the method according to the invention lacquer for lubricant applied on the still uncured profile and then injected in saline replete on lacquer for lubrication as such by molten salt. Thus, after exiting molten salt have a profile that you can easily use in the future. Designed so the profile has significant advantages. It is necessary first of all to mention dry surface and low coefficient of friction. While clearly superior options stability during storage may easy and clean handling, while the effect of lubricant remains permanently stored, as opposed to covered in silicone emulsion profiles lacquer for lubrication remains stored on the surface of the profile. Is the clutch surface profile with varnish for lubrication, which is provided correspondingly long service life. Due to this fixation nail lubricant on the surface of the profile disappear necessary to present significant costs on the Windows clear, not only by the first cycle, but in the subsequent cleanup activities. In addition, the advantage is that there is no negative impact on the paint work applied to the profile of varnish for lubrication. Thus, in General, be made available to the method, which provides manufactured product significant benefits, CCA for lubrication, because he is undergoing this process in the salt melt. In addition, due to curing salt melt is ensured uniform curing varnish for lubrication over the entire surface of the profile, even when this surface is made due to the profile is not uniform, but has cavities and other irregularities.

In a suitable embodiment, the invention provides that the length of the path between the coating and the salt melt is chosen long enough to ensure the release of volatile components. This embodiment of the invention allows the use of lacquer, which is made on the basis of the compounds of polyurethane, silicone or Teflon, their derivatives, modifications, or mixtures of solvents. Due to the fact that volatile components are allocated in advance, i.e. before immersion in the molten salt, optimum curing in the salt melt. It was found that it is sufficient segment of the path length of 0.25 to 3 m, preferably 1 m to ensure the emission of volatile components.

Another expedient embodiment of the invention provides that the nail lubricant sprayed, nlac for lubrication can be applied using various technologies, the thickness of the layer should be 3 to 4 μm, in order to provide the necessary stability during storage, as well as the corresponding term of service after the installation of the profile. This technology allows the application to provide only a partial region of the profile varnish for lubrication or the entire surface, with the possibility to extend the profile through the bath with varnish for lubrication or dipping it in her.

If for technical reasons, do not provide sufficient curing varnish for lubrication using molten salt, according expedient variant of execution of the invention the profile after coating and before entering the molten salt and/or after exiting the salt melt can be processed by means of a device using hot air, infrared radiation or ultra-high frequency. More precisely we are talking about pre-or post-processing of the profile, in this case, as mentioned above, as a rule, sufficient curing salt melt, as a rule, it can be aborted in advance if this allows the vulcanization process. Among other things, unexpected way was that caused the layer of varnish does not influence negatively on the process in the 4 ám.

To identify the profile should provide different information. To do this, as you know, on the profile type instructions and data. This should draw attention to the fact that these identification characteristics were preserved, at least to installation. According to one variant of execution of the invention it is provided that the profile is printed before coating. This has the great advantage that then identification signs are located under a protective layer of lacquer for lubrication and can be easily detected. They cannot be inadvertently erased or removed in another way. This has obvious advantages for both the manufacturer and the consumer with quality problems.

Simple and customizable embodiment of the method lies in the fact that the profile is printed using an inkjet printing device, because in this way it is possible not only to fulfill the wishes of the customer relative to the profile and coverage, but also relative to the desired information.

In the automotive industry, where, as mentioned above, already known lacquered for lubrication profiles were found to have the disadvantage that the use of solvents, cotocollao to the invention, what use varnish for water-based lubricants. These solvent-free system can be freely processed and they may not result in changes to the profile, and is also provided with profile parts, respectively, of window systems.

As for ease of installation, and for adaptation to the respective applications is preferred if the coating, i.e., nail lubricant enriched with particles of paint. Using such colored varnish can somehow varnishing profiles, which, as mentioned above, brings advantages during installation and subsequent use. In accordance with this different region of the surface varnish for lubrication of various colors without prejudicing subsequent cleaning Windows or other works. Theoretically it is even possible to put then on the colored areas of lacquer for the lubrication of other lucky for grease or a similar system.

To implement the method is set, which contains the extruder, molten salt, coating and printing area. The uniform and reliable curing of the applied varnish for lubrication is ensured by the fact that the plot for the coating is located between the sustainability of salt bath to simultaneously achieved, that can also be used with solvent-free lacquers for grease, volatile components have come before entry into the salt melt. So then, can not happen the formation of bubbles and to experience other problems. This formation of bubbles is prevented naturally when using solvent-free system, however, even in this case, it is preferred availability distance to the salt bath, because it's a certain pre-curing varnish for lubrication at room temperature. A special advantage of this setup is that you can completely opt out of future large sections of curing, and that, furthermore, there is the possibility to combine the coating and the printing area, as will be explained below.

Applied to the profile on the printing area data and information remain also in the subsequent parts of the processing fully preserved, as after the production profile for a long time, if the printing area is located before the coating, as proposed according to the invention. On site printing produce the printing on the profile in venue time because the system used lacquer to provide lubrication recognition applied printed information.

A particularly simple and economical embodiment of the printing area provides that it is made in the form of managed personal computer ink jet printer. While this embodiment has the additional great advantage that you can simply fulfill the wishes of the customer, as using a personal computer can be applied also changing print. Thus, virtually every single printed information may differ from the subsequent and previous.

Providing particularly preferred and uniform coverage of the embodiment of the coating provides that it is made in the form of a spray ring, clamping a hand or immersion baths. The spray ring makes it possible to provide the coating even at high speed of flow profile. In addition, there is an opportunity to ask and to withstand almost any thickness of the coating, so that it is possible to produce profiles of high quality.

Above it was mentioned that the curing lerno around the perimeter of the profile. If for any reason you experience problems or quality must meet particularly stringent requirements, it is possible before and/or after the salt melt to place additional device for curing a device using hot air, infrared radiation or ultra-high frequency.

Manufactured using the method described production installation profile already described in detail above. Therefore, you can refer here on this description and further noted that to facilitate the installation of the floor provide profiles of various shapes, in particular, the profiles for the construction industry. When this coating consists of put on uncured profile varnish for lubrication, which is made with the possibility of curing salt melt at a temperature 170-330oC. Although these sprays lubricate fundamentally are known, they are not used as specified for the respective profiles as purposeful application was considered difficult or even impossible. In particular, it was found that the varnish for lubrication can be applied to already cured profile only by using special processing techniques, i.e., in particular, in relation to curing. Chorus the nail lubricant is applied on the uncured profile where he can "catch" is. In subsequent salt melt it then hardens without additional system and production costs, namely, the range is so reliable that already provided above properties and advantages.

Sufficient for installation and, furthermore, does not prevent vulcanization of the coating has a thickness of 2-5 μm, preferably 3-4 mm. In this case, as already mentioned, nail lubricant bonded to the surface of the profile so that despite the small thickness of the layer ensures long service life and constant facilitate the sliding floor.

For reasons of appearance, but also to facilitate installation, it may be preferable to perform coating colour. In particular, the respectively processed profiles can preferably be used, for example, in Windows, if a colored coating provides quasi integration with the corresponding profile. When this coating is applied partial set of geometric sections of the profile, in order, in particular, to optimize the installation.

Due to the specified path length between the coating and a salt melt, respectively, a salt bath, the bubbles escogida forming a coating varnish for lubrication performed without solvent. In addition, the use of such varnishes for lubrication is more environmentally friendly and does not require a separate device for ventilation and similar AIDS.

The invention is distinguished, in particular, the fact that when applying the method, the produced profile provides a lower coefficient of friction surface. The surface is always dry and, in particular, has always provided a good opportunity handling without danger of any contamination. It should be emphasized stability during long-term storage and permanent anti-friction effect, as the varnish for lubrication formed with a surface profile quasi whole and for a long time.

The same appearance coextruding or treestructurechanged profiles for different mixtures of starting materials is preferred from the point of view of use and sale. It is possible to carry out the process reliably attach and, in addition, you can apply varnish for partial lubrication on different geometric sections of the profile, namely, transparent performance, as well as in color, even when color nail lubrication is provided, which is not impeded by the remnants of silicone or other residues of the coating, and can be carried out easily and without problems. Even when holding on to the profile with a wet cloth or other cleaning agent there is no damage and, above all, on the profile this humidity has no effect, as it also sealed with varnish for lubrication. If the window is painted, and it is the first time or subsequent, you should not expect difficulties when applying the paint, because the coating does not leave any grease residue.

As already several times mentioned, nail lubrication firmly on the profile. In addition, the advantage is that applied by spraying, clamping a brush or by dipping, or other similarly lacquer for lubrication with subsequent salt melt is solidified as evenly that you can not arise neither bubbles nor unevenly cured parts, which is always uniformly valid anti-friction effect and reliable protection with this cover. In relation to sustainability should be emphasized that with this method you can also work with solvent-free lacquers for lubrication, which are preferred to protect the environment, and, in addition, due to the absence of the robnosti of the invention follow from the subsequent description of the relevant drawings, which depicts a preferred exemplary embodiment of the invention with all the necessary details and parts:

Fig.1 - the profile section;

Fig.2 is a schematic view of the production plant.

It is shown in Fig.1 profile is an elastic sealing profile 1 for sealing Windows and similar constipation, installation wedge or tooth 3 profile which is made with possibility of installation in the groove of the plastic profile. Made correspondingly curved sealing chamfer 9 is pressed to the frame or to the glass and seals, with seal thickening 8 at one end provided with a ledge. These parts of the sealing profile 1 consists of a thermoplastic plastic. Connect them with prefabricated constipation or window shortly after extrusion already from the manufacturer. If such training is also necessary to push the appropriate profile 1 not pictured here is the groove, which must be properly deform the tooth 3 of the body 2 of the profile. This deformation and indentation greatly facilitated by the fact that the tooth 3 in this region of the surface 5 of the sealing body 4 provided with a coating 6. This coating 6 is a lacquer 7 for lubrication of the sealing thickening 8 and the sealing chamfer 9 also covered with appropriate surface 6 in the form of a lacquer 7 for lubrication, so they not only keep the surface 5 dry, but, in particular, have a low coefficient of friction, which is important for further work with them. In addition, it eliminates abrasion rubber material and depressurization of the respective seal due to scratches etc.

Needless to say that the profile 1 or body 2 of the profile may also have a different shape, and the shape of the body 2 of the profile is defined by the shape of the extruder 12, conventionally shown in Fig.2. In this production system 10 rubber or other source product is placed in the hopper 11 and then fed into the extruder 12. Between the extruder 12 and the necessary vulcanization in a salt melt 16 is provided by area 13 processing, which covers a stretch of 14 print and section 15 of the coating.

Thus, in the shown in Fig.2 schematically industrial installation 10 profile 1 after exiting the extruder 12 and in front of the entrance in a salt bath 20 through controlled by the personal computer 21 of the ink jet printer 22 provide the necessary identification signs, such as letters and numbers. When this ink jet printer 22 and the personal computer 21 provides the opportunity very quickly, Korotko customer. After printing using an ink jet printer 22 profile 1 is carried out through the spray ring 24, which here represents the portion 15 of the coating. In the spray ring or by using a spray ring 24 sprayed lacquer for lubricant from the reservoir 26 to varnish and using the pump 25 to the profile 1, namely with a given layer thickness.

As a varnish for lubrication is used, for example, compounds of polyurethane, silicone or Teflon, their derivatives, modifications, or mixtures thereof, namely with the appropriate solvents. Due to the proper discharge zone 13 processing, respectively, due to its length, it is ensured that a significant portion of this solvent is already removed again before the profile 1 is dipped in a molten salt 16 salt bath 20.

In Fig. 2 shows that the profile 1 passes through the molten salt 16 and reaches the area 17 of the cutting, where the profile 1 is cut to the appropriate length. At the exit of the molten salt 16 Lac for lubrication already overiden, namely regardless of whether it contains a solvent or does not contain. Bubbles not, and can easily be cut to a predetermined length on the section 17 of the cutting, so that then the individual segments propia length on the shipping spool and then delivered to the customer.

In addition, in Fig.2 shows that it is possible to have several spray rings 24, 27 to each other, to either apply two coats one after the other on the profile, or to supply different areas of the profile of different colored coatings 6.

All these signs, as well as those that are present only in the drawings, it should be considered separately and in combination as essential to the invention.
