Abstract

A leveling machine for steel sheet and strip includes changing cartridges between sets of leveler rolls including support rollers and adjustable crossheads. Each changing cartridge includes three cartridge portions which are connected to each other by means of two intermediate joints. The middle cartridge portion is supported on the corresponding crossheads by means of two spaced-apart rigid supports, so that only the outer cartridge portions can be limited in their pivoting positions by means of adjusting wedges or the like and, for compensating sagging of the crossheads, the leveler rolls must only be subjected to a prebending force in the regions away from the middle cartridge portion.
