in addition; EP No. 0771817A1 (US Patent. No. 17) describes the guides at the side edges of the slide and for the same purpose, the edge guides consist of a number of subdivided sectors close to the cylinders as well as between them. Furthermore it ; These individual sectors or pairs of © sectors can move individually and independently of the adjacent sectors on the tape towards or away from it in order to control the wear of the tape by friction and the lateral guide. BR No. 17197971 GB 7 describes a guide assembly mechanism for a rolling train fitted between at least two adjacent roller carriers along conveyor P0116. The aim of the mechanism assembly as well as the 0 strips used is to minimize the wear of the friction guide mechanisms and at the same time to reduce the wear of the guide strip edges. On the roller conveyors of the rolling mills, le scrolling trains, in particular strip-rolling mills, for example, for example, steel or aluminum rolling mills, it is necessary and basically that the strip is directed in a safe way and level 10, which is composed of various strip materials at various temperatures; Widths and thicknesses The more dass the tape to be directed the more a ; broader and/or thinner; The lower the contact forces required to ensure safe routing along the 0” roll and also to ensure that the strip edges do not distort (deform); and that the tape will not be punctured by US or even fully adjusted so that the tape edges or straight edge guides may be damaged. yen rn Practically; It is known that a number of different actuators adjust or compress the straight edge guides against the tape edges related to them. Mechanical actuators often include rack-and-pinion drive systems, gears, threaded rods, and sprocket arrangements. wheel chain © . Generally hydraulic external fluid. The fluid actuators are successively hydraulic, so 0 when an actuator of this type is used; In addition to the limited space requirements, rolling oils, ccooling liquids, cooling fluids, Jia, to sharp media, BES, the fact that it displays, etc., in addition to temperature, chipping roll scales, cutting roll scales, rolling oils. Generally, this leads to weariness. High guide assembly is generally harmful to guide mechanism guides 0 In addition to mechanical wear Increased wear of the actuators Excessive wear of the actuators which are straight edge guides Mechanical wear by friction; practically; There is a problem of inappropriate accessibility (DIS). In direct contact with the guiding tape for the purposes of maintenance and change of all factors or individual factors of these guiding mechanisms, which. It leads to low times for the rolling cylinder and so on, and therefore to production losses in an acceptable manner, 0 in any case; The person who is expert in the field is aware that changes in the operation procedure as a result of wear are only within strict limits, such as loss in another way of tape quality, and in Aldine by friction, they are seriously. General description of the invention In the strip-working plant, the guide assembly, therefore, the aim of the invention is to provide a guiding mechanism 0 that is included on the positionable routers, and it is better to parallelize it at both strip-working plant, so that the guides can guarantee “strip for longitudinal edges ven

safe and straight tape guiding operation by positioning of the guides; And also in order to say the vulnerability of the actuators to frictional wear completely by means of a significant decrease in the possible recession periods. It achieves the goal in an innovative manner by means of a guide assembly mechanism with characteristics according to 0 to protection element No. 1. Useful representations of the invention are known in the dependent claims. The invention, lil, is concerned with guiding guide assemblies of the previously described type as used, for example, in strip-rolling mills at the entrance side (1 to receive), the input and/or the output side of carriers roll stands for example; Die stickel machines for rolling steckel and turning (reversing) the roll holders in 0 cold rolling machines or at the inlet side and / or the production side of the roll holders that are arranged in tandem and especially against the direction of the upstream or in The direction of downstream il for coilers. The invention may be applied in order to have all types suitable for Jeg strip, in particular metal rolling mills or plastic deformation trains, from 0. It is preferable in particular to have a lead guide assembly mechanism. To a invention on a side against the direction of the upstream current or in the direction of the downstream current of at least one rolling stand in the complementary rolling machine or what is called the final rolling machine (finish rolling mill) providing guides ides that are positionable and preferably Parallel to each other in the guide assembly mechanism, according to the invention, so that it can be centered or Gals tape Ye operating in any operating device (Jes working device in particular between forming systems forming arrangements; Me on For example, roll stands.At least one guide will affect at least one operator in order to ensure a wide range of application for AEA machines.

Routing for various strip profiles or dimensions 0 in case only one routing position can be changed or pressed; The operator Load affects the position of the corresponding guide through the compressed guide and through the guide strip itself. anyway ; In the preferred case where the guides can be set directly at both longitudinal edges of the bar and each guide has its own Low actuator according to the invention; The 13g actuator must provide the method so that the variable pistons are connected in the cylinder with the straight edge guide 0. The cylinder in the piston successively forms a guide beam assembly and incorporates it into it. Thus and therefore + it is assumed that the guiding pillar is not only the function of the guiding itself but also the function of the cylinder of the piston attached 0 to the guiding. Because the piston joins the guide, any movement of the piston in the cylinder embedded in the guide beam affects the direct movement and the equal movement of the guide along the guide beam. Therefore, this position ensures the safe and non-delayed position of the router or guides relatively with the longitudinal edges of the tape to be operated. Because the cylinder is incorporated into the 0 55) direction of the operator only it has a minimal number of spaces (compartments) where sharp media may catch or collect; particle matter; etc. Furthermore it ; using the actuator arrangement (system) according to the invention; Occurrence of the so-called "Cua" drawer effects, foreign matter collected in the large hollow space or cavity that may lead to blockage of the arrangement, particularly in the case of a machine to reduce the reduced volume of the space or cavity. This allows friction of the individual components of the actuator and guide assembly to be reduced to a minimum. Veut
