- the required manufacturing steps usually include straightening to produce flat and low-stress (steel) strips or sheets.
- straightening the material is bent several times with or without train in leveling machines using straightening rollers to produce the desired straightening effect.
- the product is usually passed between a group of upper and lower straightening rollers and plastically deformed by appropriate adjustment of the upper and lower straightening rollers.
- it requires a bending radius, which is different depending on the strip thickness or sheet thickness and yield strength of the product or material to be straightened or can be and which is realized in each case by means of suitable roll diameter, roller pitches and roller immersion depths. In this case, the smaller the roll diameter is formed, the greater the possible plastic deformation of the product or material.
- Roll diameter given roll pitch, which is the center distance between two adjacent rolls, and given immersion depth and the given or desired plastic deformation in each case only a defined product spectrum or material spectrum can be directed, which depends on the respective product thickness and its yield strength.

- Straightening rollers and support rollers to be replaced by means of a removable cassette.
- each straightening roller segment comprises at least one layer of support rollers and at least one associated straightening roller.
- the invention thus proposes a modular straightening tool
- the respective modular straightening tool or the respective tool module consists of a modular segment, which in the manner of a replaceable
- each straightening roller segment has at least one layer of support rollers and at least one associated straightening roller.
- the respective straightening roller segments thus form modular segments which each form a tool module, the upper and / or lower bearing frame representing the tool carrier. This makes it possible, the upper and / or lower bearing frame with a variable number of modular
- Straightening roll segments or tool modules alternately and interchangeably equip, each consisting of straightening roller and back-up roller combinations with different diameters, pitches, roll materials and are each selected for optimal adaptation to the particular task to be performed, especially the material to be straightened. It is possible, only single modular straightening roller segments or all
- Sheet metal parameters and tool load history i. the straightening roller load history, done. Single straightening rolls of a leveler are used during the
- Another advantage of the invention is that now only smaller in terms of weight units have to be replaced in a straightening machine. This makes it possible to work with crane capacities that have a lower load capacity than those that would be necessary if any Straightening rolls comprehensive complete set of a straightening machine as a whole would have to be replaced. Likewise, the space required for a single modular straightening roller segment is less than for a complete set of straightening rollers. The low weight and smaller dimension of a modular straightening roll segment compared to a complete set
- Straightening rollers and / or support rollers also makes it possible to
- the service life / tool life of the tools can be standardized.
- the invention provides that the modularly matched straightening roller segments are formed individually or in groups interchangeable and arranged in the upper and / or lower bearing frame. This ensures that a complete, at least comprehensive flexibility is ensured with regard to the positioning of individual straightening roller segments.
- the leveler particularly flexible interchangeable with straightening rollers it is advantageous according to the invention, when both the entirety of the in the upper
- Bearing frame as well as the entirety of the arranged in the lower bearing frame straightening rollers and support rollers in several each modular
- Straightening roller and / or support roller diameter and / or with respect to the respective straightening roller and / or support roller number differently equipped with straightening rollers and / or support rollers types of modular straightening roller segments and / or change cassettes is divided.
- Straightening roll segments each form a change cassette and are each coordinated so that they form in their entirety a cassettes formed from mutually exchangeable change cassette system.
- the invention is therefore further characterized in that the individual modular straightening roller segments individually or in groups mutually exchangeable change cassettes one
- Such a change cassette system may comprise different sized types of modular straightening roller segments and / or change cassettes, which the invention also provides.
- the change cassette system differently with respect to the respective straightening roller and / or support roller diameter and / or with respect to the respective straightening and / or support roller number equipped with straightening rollers and / or support rollers types of modular straightening roller segments and / or change cassettes, whereby the invention continues distinguished.
- the invention finally also provides that they have means for detecting and / or storing material parameters of the material to be straightened and / or means for detecting and / or storing process parameters acting on each modular straightening roll segment during a straightening process and / or state parameters that adjust themselves after a straightening process on each modular straightening roll segment.
- the modularly matched straightening roller segments are each exchangeable, complex elements of the straightening machine, each of which is a closed functional unit and insofar a
