Description

PROCESS FOR LAMINATING FINISHED PROFILES FROM INITIAL PROFILES THROUGH A DESIGN OF ROLLER STRUCTURE WORKING IN REVERSE FIELD OF THE INVENTION The invention relates to a process for laminating finished profiles from initial profiles by designing structures that work reversibly in a roller line, of which one is a compact roller group, composed of a universal input structure, a second universal output structure, and an intermediate pressing structure that lies between these two; and the other is an initial roll group composed of a vertical and a horizontal roller structure and / or universal structures. The rolling of profiles of wall plug and square profiles, and of any other similar profile, until now, was carried out in a rolling mill train, which worked continuously and where the large number of sizes they were required for the initial lamination of these profiles, and the large number of the increasing length of the base of the roll sizes required large roll structures. These large structures and the rollers, as well as the manipulative facilities necessary to introduce the material to be laminated, within the different calibers, were inconvenient, and they occupied a large space, as well as their efficiency was relatively low. The large amount of material to be rolled had very long rolling times, when rollers were used that work in reverse, and therefore, did not allow to work with this type of facilities in sequences of work frequency with installation of pressure molding . For this reason, in this type of commercial activity a large space is required between the pressure molding installation and the roller installation. In addition, when rolling continuously, especially square profiles and steel profiles in the shape of "U", requires six or more roller structures with their respective propellers, this because of the large number of calibers. Apart from this, the great inconvenience mentioned above, represented high costs, to have on hand a large number of rollers to be changed and worked. Furthermore, in this type of initial and final continuous rolling, the difference in temperature along the material to be rolled can not be avoided. The so-called temperature arcs between the start and the end of the length of the material to be rolled, are produced by the relatively slow speed of introduction of the material to be rolled within the first structure of the rolling roller mill. This type of temperature arcs must be equalized as well as regular, in order to comply with the requirements established by the tempering installations on the material to be laminated. Previously, it had already been proposed to combine a small number of wall plug profiles and square profiles of different types with "H" beams in the facilities mentioned at the beginning, in which only beams had been laminated to date. form of "H". But since in a commercial activity the production of beams in the form of "H" is carried out in a pressure molding installation, that is, without a reverse structure, the mixtures with wall and square plug profiles are only they could carry out with additional facilities and the transformation of others.

OBJECTIVES OF THE INVENTION The objective of the invention is to carry out a lamination of wall plug profiles, square profiles and similar profiles, with the help of roll structure installations, constructed in accordance with the design of the roller structure, and at the same time use as primary products either rectangular blocks molded by pressure or initial profiles that were previously molded as close to the primary product. With this, the maximum reduction in the calibers required during the rolling steps must be achieved, in order to achieve an efficient formation within the production times of the commercial activities with pressure molding facilities and roller trains.

BRIEF DESCRIPTION OF THE INVENTION The objective is solved in the following way: one or more of the structures of the initial roller group and / or one or more of the structures of the compact roller group are equipped with optional calibers that can be inserted or Remove from the roller line, or slide the material to be rolled diagonally on the rolling line, and calibers placed side by side, respectively, can be used to transform the initial profiles already formed, to a rectangular shape or whose measurements are as close as possible to the final measurement in the roller structures of the initial roller group, through a series of form-reducing lamination channels and / or through transformer channels, or if necessary, and to form it reversibly using optional calibers or not; and then, in the compact roller group, if necessary, in several transformer and reducer channels in the universal input structure. If required, it will continue to form in the intermediate pressing structure, using or not the optional calibers, which are located side by side respectively, of the roller structures. And then, in the universal outlet structure or in the intermediate pressing structure, if still needed, also with the intervention of the optional calibers of the roller structures, which are located side by side respectively, they are finished form the profiles. With this process the group of initial rollers can work with or without the free exit of the material to be laminated between both groups of rollers or it can also work with a roller line placed diagonally to the roller line of the compact roller group. The initial roller group can, in this case, be composed of one or more roller structures. Horizontal, vertical or universal roller structures can be used, as well as the combination of different types of roller structures. By using universal roll structures, these can be developed as combinations of structures that optionally work as double structures. In carrying out the process according to the invention, with an initial roller group and a compact roller group, which have a universal structure or a double vertical structure and a double horizontal structure, and its intermediate pressing structure that presents two or more optional calibers, the initial profile, which was reduced by pressing on the initial roller group, can be finished in a reducing way in the universal input structure and in the optional calibers of the intermediate pressing structure in a channel reversible and in the universal output structure. With a group of compact roller and an initial roller group, which have a double vertical structure or a universal structure and a double horizontal structure, and its intermediate pressing structure has one or more optional calibers, there is also the possibility of proceeding in such a way that the initial profile is reduced by pressing in the initial roller group and can be finished rolling with the profiled rollers presenting the double horizontal structure, in a channel or several reversible channels transforming the profile; and in the following reversible channels, between the universal input structure and the optional calibers of the intermediate pressing structure, the profile can be reduced and transformed into the optional calibers; and it also ends by transformation in the universal structure of output. With a group of compact rollers and a group of initial rollers, which have a double vertical structure or a universal structure and a double horizontal structure, which are composed of an input and output roller structure, each with intermittent double rollers, with two or more calibers and, that they are provided with a diagonal sliding installation for the material to be laminated and with an intermediate pressing structure with or without optional gauges, in accordance with the invention it is possible to proceed in such a way that the profile already formed and the profile pressed in the double vertical structure or in the universal structure of the initial roller group, it is finished by forming the profile in one or several reversible channels in the optional calibers of the double horizontal structure, and then reversibly enged in both gauges placed next to each other of the input roller and output roller structures of the compact roller group, or if necessary with the incorporation of the intermediate pressing structure. When using an initial roller group and a compact roller group with a double vertical structure or a universal structure and a double horizontal structure, presenting a structure in input and output row with pairs of double rollers with two or more calibers, and that they are provided with a diagonal sliding installation for the material to be laminated and an intermediate pressing structure with or without optional gauges between the two row structures, the process will be carried out in this way: the profile already formed or the profile initial with a rectangular cross section can be finished by forming profile, in the universal structure equipped with horizontal rollers profiled from the initial group of rollers, through channels between both roller structures, and then reversibly in the sizes of the structures in row, including or not a channel in the profile rollers that presents the structure of pressing intermediate. With the present process described and the designs of the structures, only low performance can be achieved. Also the transport to the profile formed by rolling in the structures in a row, can cause technical problems. In general, only wall-plug and U-shaped profiles can be produced, but not the "Z" -shaped profiles that are now so popular in the market. The aforementioned disadvantages are eliminated, as well as the lamination of wall plug profiles and the lamination of both "U" -shaped cross-section profiles, and "Z" -shaped cross sections in all sizes; as well as the good performance of the design of the roller structure according to the invention can be provided. The initial roller group has an output roller conveyor in a roller line and a diagonal conveyor installation, and, in a second roller line, a parallel input roller conveyor, for the group of compact row structures. And the horizontal structure of the initial roller group and / or the intermediate pressing structure of the group of compact row structures, each have two optional calibers, and the universal output structure of the group of compact row structures has one or more structures double horizontal with rollers of calibers, and to the laminar, with this design of structures, the adaptation of the width and of the form of the initial profile with cross-section in the form of "H", is carried out at the same time the reduction of the transversal cut , in the group of transversal roller, and the subsequent reduction of the cross section and the formation of the profile terminals, for the formation of the lock, is carried out in the group of compact row structures, and the final formation of the The profile lock is made in the gauges of the double horizontal structure. The previously described process with an initial roller group and a compact roller group having a double vertical structure and a double horizontal structure, and wherein its intermediate pressing structure has two optional calibers, in which the initial profile is finished forming by reduction in the initial roller group and after each profile transformation in the universal input structure in the optional calibers of the intermediate pressing structure, in a continuous reversible channel, in the universal output structure, is appropriate for the lamination of profiles of force piles, of initial profiles molded by pressure with a cross-section in the shape of "I", in such a way that, when equipping the horizontal structure of the initial roller group and the intermediate pressing structure of the roller group compact, with optional gauges, the initial profile is pressed into the vertical structure of the initial roller group, already co ntinuación is reduced and transformed into the optional calibers of the double horizontal structure of this initial roller group, and is still reduced in the optional calibers of the intermediate pressing structure, and to finish it ends up forming in the universal output structure . The previously described process, in which the initial roller group uses a double vertical structure and a double horizontal structure, and the compact roller group is composed of a row structure of input and output, and each with a pair of double rollers having two or more calibers and provided with a diagonal sliding installation for the material to be laminated and an intermediate pressing structure with or without optional calibers between the row structures, is carried out in such a way that the profile already formed or the initial profile with a square cross section, is formed by transformation of the profile into horizontal profiled rollers that has the double horizontal structure of the initial roller group, and then it ends up forming reversibly in the sizes of both structures in row, including or not a channel in the intermediate press structure having profiled rollers. This process is appropriate for laminating caterpillar structures. In this case, initial profiles are pressed with a rectangular cross section or with an "I" shaped cross section or also with a slightly thickened base in the initial structure of the initial roller group; then the profiles are formed in the horizontal structure of this group and then they are finished rolling in two or three series of channels and reversible channels, with or without connection with the optional calibers of the intermediate pressing structure in the structure group in compact row. The invention is explained in more detail with the help of the drawings which show the examples of use.

Figure 22 shows the design of a roller structure seen from above in a schematic presentation. Figure 23 shows a plane of the channels for the design of the roller structure of Figure 22.

DETAILED DESCRIPTION OF THE INVENTION As can be seen in Figure 1, the initial profile VP adapts as best as possible to the finished profile, is pressed horizontally in a first channel in the vertical double VDG structure and then vertically in the double horizontal structure. The profile leaves the roller groups composed of the mentioned structures and enters through a channel 3 into the universal structure EUG of the compact roller group. This channel is followed by a channel 4 through the first optional gauge WKI of the intermediate pressing structure and another reversible reduction channel 5 in the same optional KI gauges. The next channel R6 passes with reversible direction by the universal input structure and then again as channel 7 by this structure, in both cases under a continuous reduction of the strength of the profile and then, like channel 8, it goes through the following Optional gauge WKII of the intermediate press structure. This is followed by a reversible channel R9 through the same optional gauge with a continuation in the reduction of the profile, which is renewed in the reversible direction in an RIO channel and passes through the universal input structure EUG and reversibly joins a channel 11. in the same structure. The initial profile that leaves the structure, which almost reaches its final form, ends up forming channels 12 and 13, which are one above the other, through the third optional gauge WKIII of the intermediate press structure SZG and of the universal structure of exit AUG. The channel plane of Figure 2 differs from Figure 1 because the initial profile VP is horizontally reversible pressed in three channels 1, R2 and 3 in the vertical double VDG structure of the initial roller group and then, as shown in Figure 1, it is pressed vertically in the double horizontal structure and then transformed in the same manner as in the plane of the channel of Figure 1. In a manner similar to that described, in the plane of the channels of Figure 3 , the initial profile VP with a rectangular cross-section, is pressed horizontally in the universal structure UG of the initial roller group in a channel, and then it is still pressed in the double horizontal structure in three or more reversible channels 2, R3, 4. Then, a reductive and transforming formation of the profile follows in the compact roller group in each of the continuous channels 5 and 6, reversible R7 and R8 and 9, 10 in the universal input structure EUG and in the first caliber of the optional calibers KI and WKII of the intermediate press structure SZG. And it finishes forming with the channel 13 in the universal structure of exit AUG.

In the channel plane according to Figure 4, the initial profile VP is pressed horizontally in the first channel 1 in the vertical double structure VDG of the initial roller group and then formed by transformation in a second channel 2 in the horizontal double structure HDG . In two following channels 3, 4 in the universal input structure and in the universal output structure, in a reversible channel R5 in the same structure and the channels that follow R6 and R7, it is strongly transformed in the first WKI caliber of the SZG intermediate pressing structure and then again, in the universal input structure EUG the final profile formation is carried out, in two channels 8 and 9 through the universal input structure EUG and the second optional gauge WKII of the intermediate pressing structure. The plane of the channels according to Figure 5 corresponds to the first three channels of Figure 4. After channel 3 in the universal input structure EUG follows a reversible channel R4 by the same structure and a following channel 5 also by the same structure. The universal structure of the AUG output is not used in this case. Then follows the channel 6 that passes through the optional gauge WKI of the intermediate press structure SZG and to this is joined a following reversible channel R7, which again passes through the universal structure of entry EUG and also a subsequent channel passes through this same structure, by channel 8, and by two channels 9, and passes through the second optional gauge WKII of the intermediate press structure SZG and now passes through the universal outlet structure AUG where the profile ends up forming. In the plane of the channels according to Figure 6, the initial profile VP, with a rectangular cross section, is pressed into a channel in the double vertical structure and is formed by reduction and transformation into three following reversible channels 2, R3 and 4 with Profile rolls of the double HDG horizontal structure. The shape achieved is further reduced and transformed into the compact roller group by two channels placed one above the other 5, 6 in the universal input structure EUG and in the first optional gauge WKI of the intermediate press structure, and the same happens in the following reversible channels R7, 8 and 9 which also pass through the universal input structure EUG and the first caliber KI of the intermediate press structure SZG. A reversible next RIO channel and a following channel 11 again pass through the universal input structure EUG. These channels are followed in the same direction by a channel 12 passing through the second optional gauge WKII of the intermediate press structure SZG, and the finished channel 13 passes through the universal output structure AUG.

The plane of the channels according to Figure 7 differs from those of Figure 6 in general because the initial profile VP shows a cross section similar to the cross section of the final profile and suffers an initial transformation in the first channel 1 of the vertical double structure , which then, in the double horizontal structure, which in this case has two optional calibers KI and WKII, passes through the first optional gauge WKI as two reversible channels, and then pass two channels 3 and 4 through the second optional gauge WKII of the double horizontal structure. The formation that follows is carried out in the same way on channels 5 to 13 as in the sequence of channels of Figure 6. The channel plan according to Figure 8 corresponds to that of Figure 7 with the measurements, only that here the initial profile VP is formed in a channel of the universal structure UG of the initial roller group, in the manner as required for the second channel in the optional gauge WKI of the double horizontal structure HDG. The following channels R3 to 13 correspond to those of Figure 7. In the channel plane of Figure 9, a first channel 1 is pressed horizontally to the initial profile PV with a rectangular cross section in the vertical double structure, and in a second channel 2 in the double horizontal structure it is transformed with profiled rollers, in such a way that it can then be finished forming in the compact roll group in the row structure ETG and ATG in each of the channels 3 and 4 which are one above the other and reversible in R5, R6, and in the opposite direction in the following channels 7, 8 in the same calibers. In the channel plane of Figure 10, the initial profile PV, whose cross section is similar to that of the finished profile to be rolled, and therefore does not require an initial pressing in the initial roller group, and in the calibers formed by the profiled rollers and in three reversible channels 1, R2 and 3, it is reduced and formed in such a way that, after the following reducing channels 4, 5 pass through the structure in ETG input row, and that the structure in the ATG output row in two reversible channels R6 and R7, which are one above the other, pass through the same line of gauges, where the 5 gauge is stopped, a pulse function is achieved and it is transported to the cylindrical roller by 4. If necessary, the gauge 4 must be opened a little. Then on channels 8 and 9, through the other gauge line of both structures, the cylinder is finished. The plane of the channels according to Figure 11 differs from that of Figure 10 because between the ETG and ATG row structures of the compact roller group, an intermediate SZG pressing structure is placed, so that the initial profile already formed that it leaves the initial roll group, is finished forming in three channels 1, R2 and 3 and then in channels 4, 5 and 6, and passes through the lines of calibers of the structures, and in the reversible channels R7, R8 and R9 passes through the same line of gauges, and then the finished profile is produced in channels 10, 11, 12. In this roll structure design, a three-structure row-type reverse train is used, and all three structures have the same structure. same length in the bases, for example, of 1500 millimeters, that is to say, not only the universal structures ETG and ATG can be used for combinations and can work as double structures with the same length in the bases, but also the structure of the press The intermediate can be transformed into a double structure with the same length in the bases. Then, the sequence of channels is in the group in row 4, 5 and 6, it is returned to the same line of the caliber, where for channel 6 it rises slightly to the caliber, the same with channel R7. The channels R8 and R9 really only represent empty channels. In channels 4 and 5 the calibers remain unchanged, and therefore they are very large, so the cylinder roller must be driven to pass through them. In the channel plane of Figure 12, initially an initial profile VP with a rectangular cross section is formed in the universal structure UG and in the horizontal double structure HDG of the initial roller group, and both are equipped with profiled rolls, in a series of channels and reversible channels 1, 2, R3, R4, 5, 6, R7, R8, and 9, 10 and then finish forming in channels 11, 12 in both row structures ETG and ATG of the compact roller group in two reversible channels R13 and R14 placed one above the other, and in the channels that follow them 15 and 16. Just back, the 12 gauge rises slightly, and the R13 channel acquires the impulse functions to pass to the cylinder in the channel R14 for the caliber 11 that has not changed. It may be necessary to open the 11 gauge a bit when passing the cylinder through the R14 gauge. The plane of the channels according to Figure 13 corresponds to that of Figure 12 with the difference that, after the formation of the initial profile VP with a rectangular cross section in the initial roll group in the universal structure UG and in the structure horizontal double HDGF with channels 1, 2, R3, R4, 5 and 6 after two channels placed one above the other 7 and 8 with the reversible channels R9, RIO in a sequence of subsequent channels 11 through the input row structure ETG, 12, the Final formation is carried out through the intermediate pressing structure SZG which is activated and has rollers calibrated with channel 13 in the row structure. In this special case, the intermediate press structure SZG has a small length at the base, that is, it is not a structure that can be transformed as the universal structure, which in this case works as a double structure with, for example , 1500 mm, and the intermediate pressing structure with 1000 mm. This means that the intermediate pressing structure SZG for channels 7, 8, R9 and 10 is brought to the roller line by a sliding and has to be opened sufficiently so that the profile can pass without any problems. For channel 12 the intermediate pressing structure is again slid to the line of gauges 11, 12, 13. The channel plane according to Figure 14 corresponds to that of Figure 13 with the measurements; here an initial profile VP is used whose cross section is similar to the cross section of a finished profile. The formation of this initial profile VP is carried out in the universal structure UG and in the horizontal double structure HDG of the initial roller group with the same sequence of channels 1, 2, R3, R4, 5, 6 as in the plane of channels of Figure 13. Unlike this channel plane, the row structure of the ETG input and the row structure of the ATG output arrive directly through the sequence of channels 7, 8, and then continue in the same calibers of this structure one step from R9 or RIO. Next, the formation corresponds to the channels 11, 12, 13, again as in Figure 13. The plane of the channels of Figure 15 corresponds to the principle of Figure 13, but differs by the formation of the initial profile VP in the universal structure UG and in the double horizontal structure HDG of the initial roller group, since in this case a profile transformation is carried out in a channel 1 and in a reversible channel R2 in the horizontal double structure HDG, which the formation that follows joins the series of channels 3, 4 with the reversible channels R5, R6 and the channels pass through the universal structure UG and the horizontal double structure HDG 7, 8. The formation in the compact roller group corresponds to the channels 9, 10, the reversible empty channels Rll and R12 through the line gauge of the ATG output row structure, and the row structure ETG with the sequence of channels 13, 14, 15, and the structure of intermediate pressing of Figure 13 as in Figure 14. When using an intermediate pressing structure SZG according to the planes of channels 13, 14 and 15, the intermediate pressing structure SZG has to slide diagonally in such a way as to impede the passage by the calibres of the material to be calibrated, since the roller lines of the row structure are very close to the sequence of channels in the row structure, and a formation is not carried out in the intermediate pressing structure. In the plane of the channels according to Figure 16, the initial profile VP, which has a cross section similar to the cross section of a finished profile, is formed as a shape transformation in the universal structure UG of the initial roller group in a channel 1, and then it continues to be transformed into a first WKI gauge of the horizontal double structure HDG in a channel 2 and is reduced in the next channel R3 and the reversible channel R4 in the optional gauge WKII. In the compact roll group the formation according to Figure 12 is carried out, which after the empty channels 5, 6, passes through the line gauge of the ATG output row structure in the reversible channel R7 , R8, and goes through this line of calibers and the sequence of channels 9, 10 through the other line of calibers until reaching the final formation. The plane of the channels according to Figure 17 corresponds to that of Figure 16 with the measurements; in the channel 1 of the initial roller group is not carried out in the universal structure but in the double vertical structure with the corresponding profiled rollers. The plane of the channels according to Figure 18, which in terms of the initial profile VP that is used, whose cross section is similar to the cross section of the finished profile, corresponds to the universal structure UG with profiled rollers and the double horizontal structure HDG with two gauges WKI and WKII, to the development of the initial roller group of Figure 16, and also corresponds to the compact roller group, and it ends up forming in the channels that are on top of each other and the reversible channels 1, 2, R3 , R4, 5 between the universal structure and the caliber KI of the HDG horizontal structure, and after a channel 6 passes through the other gauge WKII of the horizontal double structure HDG with the channels one on top of the other 7, 8, and the reversible empty channels R9, RIO pass through a line of gauges of both row structures ETG and ATG of the compact roller group in a next step with channels 11 and 12 corresponding to that shown in Figure 16. In the plane of the channels according to Figure 19, the initial transformation is carried out in the initial channel 1 in the first optional caliber KI of the horizontal double structure HDG unlike in Figure 18. This channel is attached to a channel reversible R2 through the same caliber, to which two subsequent channels 3 and 4 are again reversibly connected through the UG universal structure and the same optional WKI caliber, and this is followed, reversibly, by two R5 channels and R6 by the same caliber. In the channels that are joined 7 by the universal structure UG and 8 by the optional second gauge WKII of the double horizontal structure HDG, the initial profile VP is already formed in such a way that, then, in the way that was already described , the first gauge of the ETG input row structure and the ATG output row structure of the compact roller group and then with the empty reversible channels Rll, R12 passes through the gauge line and with the following channels 13 , 14 on the other line of gauges, equal to how it ends up being formed in Figure 18. In the channel plane for laminating Z-shaped wall plug profiles, according to Figures 20 and 21, the initial roller group presents, behind the double vertical structure VDG, a horizontal structure HDG with two calibers Kl, K2, as for example, the optional calibers, and behind it a universal structure UG with profiled rollers. The compact roller group is composed of an ETG input row structure, an ATG output row structure and an intermediate SZG pressing structure placed between these two. These structures are equipped with profiled rollers. In both structures in row ATG and ETG double rollers can be used. The initial profile VP, which has a rectangular cross section, or can also have a rectangular cross section similar to the rectangular cross section of the finished profile, is pressed into channel 1 of the vertical double VDG structure, and then reduced in a sequence of channels one on top of the other 2, 3 on the first caliber Kl or the optional caliber of the double horizontal HDG structure and on the following channels 6, 7; R8, R9; 10, 11; R12, R13, and then shape changes in the second gauge K2 or the optional gauge of the double horizontal structure HDG in a next channel 14 and then it is finished forming in the following three channels 15, 16, 17 in a structure in input row ETG, in the intermediate press structure SZG and in the structure in output row ATG. In this plane of channels with the universal structure, the horizontal pressing structure, the universal finished structure, and the reversible train in a row, represent a universal roller train, and the structures can work without any type of transformation. As can be seen in Figure 22, behind a heating furnace WO, which can also be a post-heating furnace joined with the pressure molding facility, which heats the molded profiles to the rolling temperature, is provided with a roller corridor RG1, which leads to the group of the initial structures, which are composed at the entrance by a double vertical structure VDG and at the exit by a horizontal structure double HDG. To this group of initial roller structures, a roll aisle RG2 is placed on the same roller line WL1. A QT diagonal transportation system leads to a roller corridor RG3 that runs diagonally, which, on a second roller line WL2, reaches the group of the compact row structure, which is composed of a universal structure of EUG input, an intermediate press structure SZG, and a universal outlet structure AUG, and provided with a roller corridor RG4, which, on the same roller line RG2, leads to the horizontal structures HDG1, HDG2 and HDG3, which are placed one behind the other and equipped with calibrated rollers. As can be seen from Figure 23, the initial profile VP is pressing on a first channel 1 in the vertical double VDG structure and is formed in a following channel 2 in the optional gauge WKI of the horizontal double structure HDG, and then it is reduced in a reversible channel R3 and in a following channel 4 in the optional gauge WKII. After this, three channels 5, 6 and 7 pass through the universal input structure EUG, the intermediate press structure SZG, and the universal input structure AUG of the compact row structure group, to which a series is connected. of reversible channels R8, R9 and RIO in the opposite direction and in the sequence of the structures; This is followed by a renewed step with the following channels 11, 12 and 13 through the aforementioned structure line. The shape of the wall plug profile that was achieved by the sequence of row-reducing channels is finished in the following channels 14 and 15 in the gauges of the double horizontal structures HDGI and HDGII to form the terminals of the locks. In the channel plane according to Figure 24, the initial profile VP is also pressed in a first channel 1 in the vertical double structure VDG and then formed in a following channel 2 in the double horizontal structure HDG of the initial roller group in the Optional WKI caliber. This shape is reduced in a reversible channel R3 and in a subsequent channel 4 by the optional gauge WKII and then further reduced by passing in a sequence of channels 5, 6 and 7 through the universal input structure EUG, the structure of intermediate press SZG, and the universal output structure AUG of the compact row structure group, and by a sequence of channels following R8, R9 and RIO and a next channel 11 passes through the universal input structure ETG. The initial formation is then carried out on a channel 12 by the second optional caliber of the intermediate press structure SZG. The terminals of the lock of the wall plug profile that was laminated in this way, is finished rolling in a sequence of channels 13., 14, 15 in the double horizontal structures HDGI, HDGII and HDGIII.
