Abstract: The straightening machine (1) comprises upper straightening rollers (5.1, 5.2), lower straightening rollers, interchangeable caskets, which are removable from the straightening machine, and a device for blocking the pivotability in the driven out condition of the concerned interchangeable casket part. The upper- and lower straightening rollers are arranged in an upper and lower interchangeable casket and are drivable via coupling elements. The straightening machine is driven passively by a movement of materials to be arranged. The straightening machine (1) comprises upper straightening rollers (5.1, 5.2), lower straightening rollers, interchangeable caskets, which are removable from the straightening machine, and a device for blocking the pivotability in the driven out condition of the concerned interchangeable casket part. The upper- and lower straightening rollers are arranged in an upper and lower interchangeable casket and are drivable via coupling elements. One of the upper and lower interchangeable caskets is separably formed in such a manner that the relevant rollers are exchangeable through removal or without removal of the upper and/or lower interchangeable caskets. Transmission- and drive shaft arrangements are arranged for active propelling of the straightening rollers via the coupling elements. The straightening machine is driven passively by a movement of materials to be arranged. One of the interchangeable caskets has a bearing arrangement for connecting the rollers with the transmission and drive shaft arrangements, which are mechanically coupled via the coupling elements. The straightening rollers- and coupling arrangement are drivable together or separately from a work area (4) in the straightening machine. The upper and lower interchangeable caskets are arranged on upper and/or lower sliding plates (8) that are drivable from the work area in the straightening machine. One of the sliding plates is formed in multi-piece manner. The separation proceeds between the straightening roller bearing arrangement and the coupling elements. A holding device is formed in the form of an arrangement of clamping cylinders for influencing the sliding plate part on the upper interchangeable caskets to specify the sliding plate at a structure drivable from the work area of the straightening machine. A part of the holding plate with the concerned sliding plate or the concerned sliding plate part is drivable from the work area in the straightening machine. The upper and lower sliding plates are guidable together with the upper and lower interchangeable caskets. At the straightening machine, a coupling device is intended for coupling the interchangeable caskets parts of the upper and/or the lower interchangeable casket. One of the upper and lower straightening roller-bearing arrangements for enabling a straightening roller inflection is pivotable. An independent claim is included for an interchangeable casket arrangement for a straightening machine.
