¢ compressible and f; As a result; have limited technical capabilities with regard to, for example, the control of the compressive reducing forces; lighter streaks; 1 for hotter; 1 to widest; and/or} for insomnia. General description of the invention for this; The object of the invention is to provide a guide device in an assembly of shape-modifying materials which 0 includes an extension parallel to each other; Edge guides which are ALE for placement on both longitudinal sides of the material and which are well suited for the reliable adjustment of the pressures applied to the deformable edges of the material which are noticeably reduced compared to the maximum pressure applied and thus allow to adapt the possibility of use for routers with light cross-sections; of equal breadth and/or particularly thin aL eg; thinner strips; while at the same time preventing the tape from being damaged” in particular; In the region of the edge region is faulty. This goal is achieved; According to the invention » with a router with element (©) features. Other embodiments of the invention are defined in the subsidiary claims. The invention investigates guide devices of the aforementioned type which are used in strip rolling mills; For example ; at the inlet and/or outlet side of 10 allll mill stands such as cSteckel rolling mill opposite cold rolling mill stands or at the inlet and/or outlet side of tandem rolling mill stands and; In particular” in front of or behind the coilers 1 of an invention usable for the deformation of every conceivable material; But especially in metal rolling mills or plastic deformation trains, it is particularly useful; however; When arranging the inventor's router at the entrance side

° or the outlet side of at least one rolling mill holder of a final rolling mill locomotive of the so-called finish rolling mill or in front of the coiling installation.

According to the invention; in the guide device; two are arranged; Edge routing tools 8 m. They extend parallel to each other on each of the longitudinal sides of the material

© with which the centering and/or alignment of the ALE material is performed to modify the shape in the shape modification installation and in particular; Among the shape modification combinations quot; For example “rolling mill stands” to ensure wide utilization possibilities of guide devices for different materials; preferably strip dimensions; One edge guide is exposed on

The minimum pressure applied directly by at least one positioning device. in

0 case when only one edge guiding tool is subjected to pressure applied by the corresponding locating device; the positioning device; through exposure to pressure ¢

Edge guide and through the same replaceable material places the corresponding edge guide. in the useful case; however; When the edge guide tools on both longitudinal sides are directly subjected to pressure; Each edge pointer has a positioning device

its own 0.

In order to ensure that at least one locator is usable; through the edge guide tool; Precisely defined pressures of the deformable material over a wider range

of adjustable pressures, which include those that fall significantly below the maximum pressure force; includes at least one locating device according to the invention; At least two devices

0 to apply pressure; Sequentially replaceable one after the other which also cooperate with each other

: some which is the ALE of the application; if necessary two different maximum pressures. by appropriate selection of pressure-applying devices replaceable in sequence one after the other; For example; Using a relatively large pressure applicator and a relatively small pressure© applicator; Base pressure may preferably be applied with the first pressure applicator; Precise adjustment of the total pressure applied by the modulated or adjustable material edge guide tool (JEN) can additionally be made with the second pressure-applying device. In the case of pressure-applying devices it includes two of at least piston-cylinder units; in a particularly useful embodiment » the relatively small cylinder 0 mounted on or in the piston arm of a relatively large cylinder; preferably integrated into the piston rod Thus, an efficient and reliable serial replacement of piston-cylinder units is made available which clad ensures that the pressure applied by a small piston-cylinder unit is reliably added to the pressure applied by a large piston-cylinder unit. A relatively small piston-cylinder unit is usefully applicable to up to 1 max (Toor ©9672 of maximum pressure sang) of a relatively large piston-cylinder unit. In a useful embodiment also of the invention; The connection of mechanical pressure-applying devices 5 is preferably influenced by at least one rack-pinion arrangement. This preferred embodiment guarantees; by particularly simple means; Reliable positioning of each edge guide tool parallel to its counterpart inside the router and, if necessary, strictly perpendicular to the longitudinal sides of the shapeable material even when different pressure-applying devices are used.

And, as already discussed above, the invented router is not limited to a certain number of pressure-applying devices per edge router. Conversely, it is advantageous that when a single pressure-applying device is connected with at least two" of sequentially replaceable piston-cylinder units one after the other with only one edge guiding tool©. Thus, the costs of the apparatus to achieve the object of the invention are limited to a minimum. In this

the condition; Pressure is applied to each of the longitudinal sides of the material” such as strip edges ¢ when the material is compressed against an edge guide device arranged on the corresponding longitudinal side of the shapeable material; With the edge guide tool provided by the .pressure-applying device

Ye It is advantageous when the edge routing tools within the routing device are located in a manner that is not dependent on each other because it is then possible to reliably perform the operation on both sides of the shapeable material. Especial; In the case of rolling the so-called joint blank continuously with the change of thickness over the width of the tape – with the application of smaller pressure to the relatively thin side of the tape compared to the application of pressure to the side of the thick elon tape, it is possible to prevent damage to the edges of the tape (cstrip edges).

strip with simultaneous reliable routing of the VO strip with control or regulating in each case; It is useful that when organizing units at least one locating device is connected to the inventor router. In the event that different devices are available for applying pressure; It is particularly useful when they are organized or controlled independently of each other. in a particularly useful way; Be the maximum flexibility to implement the process in the installation of modifying the shape with diversity
