  • the wedge element has a base surface running parallel to the transport direction and a wedge surface arranged at an angle to it, such that by displacing the wedge element parallel to the transport direction, a lateral distance of the module from the center of the belt run can be changed or can be set to a predetermined value .
  • strip travel is the direction in which material is actually moved through the roll stand.
  • This material can be endless strips of metal. However, this material can also be metal sheets that have only a limited length.
  • the invention is based on the essential finding that, due to the displaceability of the wedge element parallel to the direction of transport, it is possible to adjust the positioning of the module on the stand frame of a rolling stand with regard to a lateral distance from the center of the belt run.
  • a targeted position of the module relative to the strip run and thus to the "real" position of the rolling stock within the system or the roll stand, in which the module is at a predetermined lateral distance from the center of the strip run, is achieved occupies or has.
  • the module is attached or fastened to the stand frame by means of the device according to the invention, and the wedge element is clamped between the stand frame and the module.
  • the use of the present invention is particularly advantageous in the event that the stands of a roll stand or the associated spars of the stand frame of a roll stand do not ideally point vertically upward, but, for example, with their upper end slightly to the side (to the outside or are tilted inwards.
  • the stands are not aligned parallel to one another, but the module can nevertheless be attached to such a stand frame with the aid of the device according to the invention.
  • a module can also be attached to a stand frame in the event that one stand on the drive or operating side tilts outwards or inwards and the other stand (i.e. on the operating or drive side) tilts to the opposite side.
  • a tendency of the stands to tilt is compensated for by wedging the wedge elements on the upper and lower edges of the module in different positions between the module and the adjacent stand frame and fastening them there.
  • the base surface and the wedge surface of the wedge element form an angle between them.
  • the contact surface of the module is complementary to the wedge surface of the device.
  • this means that the contact area in the same way in is formed or oriented at an angle, namely in the present case at an angle with respect to the transport direction, which is identical to the angle between the base surface and the wedge surface of the wedge element.
  • the wedge element can be provided with at least one through hole which runs parallel to the orthogonal, which is directed towards the base of the wedge element.
  • two such through holes are also formed in the wedge element.
  • the aforementioned shifting of the wedge element parallel to the transport direction only takes place if the module is newly attached to the stand frame of a roll stand or if a position of the module on the stand frame - with loosened Screw connection - is to be changed in order to achieve a changed distance between the module and the center of the belt run.
  • the wedge element is firmly attached to the stand frame or is immovably received or clamped between the stand frame and the module when the module is attached to the stand frame, e.g. by means of screw connection.
  • the wedge element can be displaced parallel to the transport direction in the manner mentioned when the module is detached from the stand frame of a roll stand (for example in the form of a screw connection).
  • an end plate is arranged adjacent to the base surface or wedge surface, which has a lateral projection.
  • Such an end plate and its lateral projection make it easier to move the wedge element parallel to the transport direction.
  • suitable ones Assemble mounting means for example mobile hydraulic cylinders or the like) on the lateral projection of the end plate in order to achieve a displacement of the end plate parallel to the transport direction if this is to adjust a lateral position or a lateral distance of the module horizontally to the center of the roll stand is desired or required.
  • a feather key can also be provided for the device, which is arranged on an underside of the module.
  • a key serves the purpose of supporting the module in particular on a surface or on a surface located below the module.
  • a suitable dimension of the feather key in the vertical direction or its height thus also determines or influences a vertical positioning of the module relative to the stand frame of a roll stand to which the module is attached.
  • a stop plate is provided for the device, with which the module can be attached to the inlet or outlet side of a stand frame of a roll stand.
  • a stop plate can be provided or arranged on an end face of the module.
  • the module which can be attached or fastened to a stand frame of a roll stand by means of a device according to the present invention, is preferably an inlet side module and / or an outlet side module.
  • an inlet side module is attached to the inlet side of a stand frame of a roll stand.
  • an outlet side module is attached to the outlet side of a stand frame of a roll stand.
  • a module can be attached or fastened to a stand frame of a rolling stand with little effort and a short or shortened assembly time.
  • a lateral distance to the center of the belt run can be changed or set for the module in order to compensate for any existing misalignments of the roll stand and the associated stands.
  • the present invention is particularly suitable for use in single-stand systems or in multi-stand systems (for example tandem lines).
  • a module can be attached to a stand frame 1 of a roll stand W by means of an associated device 10.
